Frequently Asked Questions

Frequently Asked Questions

The auditory system is the sensory system for the sense of hearing. Hearing has a double role :

  • Communication, through speech and exchange ;
  • Vigilance and alertness, by constantly listening to our sound environment. The ear is never at rest and begins to age from birth.

Hearing requires the existence of sounds. A sound is a wave that propagates in the air in pressure variations. Sound is defined by 3 characteristics :

  • Amplitude : determines whether the sound is weak or loud. The amplitude is expressed in decibels (dB). On an ENT audiogram, the amplitude is located on the ordinate axis ;
  • Frequency : determines whether the sound is low or high. The frequency is expressed in Hertz (Hz). On an ENT audiogram, the frequency is located on the abscissa axis ;
  • Time : expressed in seconds (s).

The hearing is exerted by the auditory system, through 2 channels :

  • The ear, which captures, analyzes and transforms the sounds into nerve impulses ;
  • The central nervous system, which interprets the sounds.

The ear is an anatomical amplifier. Its complex structure houses the auditory receptor which transforms electrical signals into nerve impulses.

• In the outer ear : the pinna, thanks to its folds and shape, captures and amplifies the sound waves which are then guided to the eardrum by the ear canal. The ear canal is an air-filled cavity that communicates with the outside world ;

• In the middle ear : the eardrum reacts to the pressure variations of the sound wave and transmits them to the ossicles (hammer, anvil, stirrup). The role of the ossicles is to mechanically amplify the vibrations of the eardrum membrane and transmit them to the cochlea (snail-shaped hearing organ).

• In the inner ear : the 15,000 or so hair cells at the base of the cochlea detect the vibrations and generate the nerve impulses that are sent to the brain via the auditory nerve.

• At the level of the nervous system, the auditory stimulus activates several brain areas, in both hemispheres : thus, a word heard activates the part of the brain that hears it and the part where it is understood. Auditory capacity only accounts for 10% of comprehension ! Cognition influences the way we hear. Indeed, most of the information processing is done by :

  • Central information processing ;
  • The subject's cognitive abilities (memory) ;
  • Life experiences (such as socio-economic status).

Presbycusis is the most common hearing loss in France and in the world. In France, presbycusis affects nearly 6 million people. Usually described as "the age-related hearing loss" because 85% of the over 65s are concerned, it is no longer the preserve of the elderly. While the average age of onset has been reduced by a decade - from 70 to 62 - many studies have shown that a quarter of those under 30 suffer from a hearing loss of more than 20dB and that one out of five teenagers suffers from permanent tinnitus.

Presbycusis is the decline in hearing related to the natural aging of the auditory system. It affects everyone, from the age of 60 onwards and concerns 90% of current hearing problems.

Progressive, presbycusis manifests itself over time, which is why it can be difficult for the subject to realize it by himself : 42% of presbycusis sufferers consult an ENT under pressure from their relatives. Presbycusis is also bilateral and symmetrical, meaning that the hearing damage is the same in both ears, except in special cases that may lead to a more pronounced damage on the right or left side. Finally, presbycusis focuses on the high frequencies (2000Hz to 8000Hz), for 2 main reasons :

  • In terms of species evolution, the high frequencies were built up in a very short time and are therefore fragile ;
  • Anatomically, the high frequencies are located in a small area at the base of the cochlea (a snail-like organ of hearing) and are therefore in the front line of sound and/or pressure attacks.

Indispensable for the proper understanding of words, the high frequencies carry the voices of women and children, transmitting the energy of the whistling or fricative consonants (f, s, t). Thus, men are the first to be bothered by presbycusis and often have those around them repeat themselves. In general, presbycusis leads to confusion between words as well as a poor understanding of sibilant or fricative consonants. The people concerned have difficulty understanding conversations in a noisy environment or with ambient hubbub (restaurant, professional or family meeting, open space) ; difficulties in following exchanges on television, radio, theatre or cinema. Although these people do not complain of hearing problems, they do stress that they have difficulty in "understanding in a noisy environment" and/or "that the youth no longer articulate". At the end of the day, they experience increased fatigue because of the effort required to understand and not to have someone repeat themselves - especially at work, where self-image and productivity are paramount. In the workplace, presbycusis is one of the primary factors affecting employee well-being.

The audiogram of presbycusis shows a decrease in hearing in the high frequencies, while the mid and low frequencies are relatively well preserved. While the intensity of the hearing loss varies from person to person, the audiometric curve remains similar, indicating the possibility of a preset hearing aid. When the hearing loss reaches 30dB, the discomfort is obvious. From this threshold, the doctor will indicate a hearing aid, which can be bilateral (on both ears) or unilateral (on only one ear).

• ENT audiogram of presbycusis hearing loss in an 83 year old patient. Since the hearing loss is greater than 30dB on both the right and left sides, the recommendation is for a bilateral hearing aid. This can be a BTE hearing aid or an ITE hearing aid, depending on the individual's preference.

• ENT audiogram of a presbycusis hearing loss in a 69 year old patient. Since the hearing loss is greater than 30dB on both the right and left ears, a bilateral hearing aid is recommended. This can be a BTE hearing aid or an ITE hearing aid, depending on the individual's preference, both types being perfectly suitable.

• ENT audiogram of presbycusis in an 84 year old patient. Since the hearing loss is less than 30dB on the left (max. 25dB on the 8000Hz frequency), the recommendation is for a right-sided unilateral hearing aid. Both types of hearing aids - BTE and ITE - are suitable and the choice is left to the patient.

• ENT audiogram of presbycusis hearing loss in a 67 year old patient. With a hearing loss of 30dB max. on the left, the recommendation may be for a bilateral or a right unilateral fitting, depending on how the patient feels. Both types of hearing aids - BTE and ITE - are well suited to compensate for presbycusis.

• ENT audiogram of presbycusis in a 78 year old patient. With a hearing loss of more than 30dB on both the right and left sides, the indication for a bilateral hearing aid is given. A BTE hearing aid is suitable, as is an ITE hearing aid.

• ENT audiogram of presbycusis in a 55 year old patient. With a hearing loss of more than 30dB on both the right and left ears, a bilateral hearing aid is indicated. Both types of hearing aids - BTE and ITE - are perfectly suitable, the choice must be left to the subject.

In general, a presbycusis hearing loss is summarized as follows by professionals :

The audiogram of a presbycusis is therefore typical, showing the possibility of a hearing aid specially designed to compensate for the damaged frequencies, thanks to a specific pre-configuration. This is what the digital CIC Orison hearing aid allows.

Unlike the eye, which rests as soon as the eyelid closes, the ear functions day and night and begins to age from birth. Hearing is exercised by the ear and the central nervous system : we are born with a contingent of 15,000 hair cells that ensure the transformation of sound vibration into a nervous message, which the brain interprets. These cells are sensitive to sound and pressure attacks. When they are destroyed, they do not grow back : the hearing loss is then irrevocable. To prevent presbycusis, it is therefore necessary to understand the different types of aggression and to protect oneself from them.

• Noise aggression

We live in a world where noise pollution is widespread, whether it is caused by us (headphones, DIY at home, disco) or not (work on the public highway, road traffic, airport) : 7 million French people live in areas of excessive noise and 2 million are exposed to noise risks in their professional environment. Noise is an integral part of our daily lives and our ears are therefore put to a severe test at all times.

Among young people, the use of the MP3 format is strongly correlated with the resurgence of early hearing loss, sound-trauma. This format, designed to lighten the weight of files, uses drastic modifications of the sound signal, the main one consisting in carrying out a dynamic compression, i.e. raising the sounds of weak level and lowering those of strong level. The sound thus levelled has no more contrast, with a double consequence :

  • The increase of the volume, to find the illusion of sound relief ;
  • The increase in the number of music files stored in our pocket, in other words, the availability of an overabundance of music that pushes us to prolong the listening time, at high volume, with headphones.

• Pressure aggression

Other types of aggression can have an early impact on our hearing health. This is the case with pressure stresses, which can be combined with noise stresses and which can be found in certain sports or leisure activities such as diving, free diving, combat sports, hunting, shooting and motorcycling, for example.

• Other factors affecting good hearing

Some drugs also have an ototoxic effect, especially in cases of renal failure. This is the case of aminoglycosides above a certain threshold, aspirin, non-steroidal anti-inflammatory drugs, cisplatin and certain anti-malarial drugs. Finally, other factors can cause hearing loss and many of them are modern ailments : diabetes, obesity, poor dietary habits, smoking.

• Preventing age-related hearing loss or presbycusis

In order to maintain good hearing for as long as possible, it is therefore essential to protect your ears throughout your life. It is recommended that you always carry noise protection with you, to be worn at the slightest excessive stress. During festivals, concerts or other places of high noise exposure, you should also add moments of auditory rest (30 minutes to 1 hour in dedicated spaces).

For music lovers, favour High Definition formats, so that it is not necessary to increase the volume. Finally, the use of headphones should be limited to 30 minutes continuously.

For scuba divers, banish the Valsalva manoeuvre, whose repeated blows increase hearing loss in the 6000Hz frequency range, and favour soft compensation methods (Frenzel or Voluntary Tubal Béance), which are a-traumatic for hearing. The latter are taught by federal instructors but it is common for an experienced diver to naturally switch to Frenzel over the years.

For hobbies such as hunting and shooting, hearing protection is recommended and, in most cases, provided. For motorcyclists, many specific protections can be purchased in specialized shops.

Finally, in general, it is recommended to adopt a healthy diet. For all the cells in the body, as well as for those of the hearing, a diet rich in antioxidants prevents ageing. Red wine, red fruit, small blue fish, flaxseed, hemp seed, turmeric and black pepper, curry, cumin, Mediterranean diet and spirulina are good examples of foods that can help prevent the effects of time and keep you in shape for as long as possible.

The auditory stimulus activates several brain areas in both hemispheres : the part of the brain that hears it and the part where it is understood. The decrease in auditory acuity leads to an impoverishment of the auditory stimulus transmitted to the nervous system and, as a result, to insufficient cortical stimulation, with a triple consequence :

  • A decrease in the volume of the primary auditory cortex ;
  • A decrease in neural activity in the areas concerned ;
  • A decrease in neural activity in other subcortical areas.

To compensate, the brain activates collateral circuits :

  • Increase in the subject's cognitive processes (concentration to hear) ;
  • Increase in mental resources ;
  • Increased fatigue ;
  • Decreased attention available for other activities.

At the microscopic level, picture A shows normal cortical layers in an individual with normal hearing.

Picture B shows the detail of a normal neuron in a person with good hearing. The neuron is composed of branches and dendrites, creating a tree structure (B1), which are key elements in the exchange of information between neurons and in the plasticity of the nervous system.

Photo C shows that after hearing damage or with the natural aging of the auditory system (presbycusis), neurons reduce the dendritic tree and a large number of spines are lost (C1).

Thus, in a vicious circle, hearing loss leads to functional changes in the brain, which reinforces the deterioration of hearing and increase the risk of cognitive decline. Some facts about unaidable hearing loss and the risk of dementia :

  • People with unaidable hearing loss are 24% more likely to suffer a decline in cognitive skills such as concentration, memory and / or planning ability ;
  • Hearing loss is linked to a 3 times greater risk of dementia ;
  • 3 out of 4 people with dementia also have hearing loss ;
  • The more fragile the hearing, the more it is linked to greater levels of cognitive impairment ;
  • Mild, moderate and severe hearing loss are associated with a 2, 3 and 5 times greater risk of cognitive decline respectively than in people with no hearing impairment ;
  • Bilateral hearing loss is associated with a 43% increased risk of dementia.

Today, worldwide :

  • 360 million people over the age of 65 have a hearing loss, representing 33% of the world's population ;
  • 47 million people over 65 suffer from dementia, i.e. 10% of the world's population.

What about the future ? In 2050, 720 million people worldwide will suffer from hearing loss and 131 million from dementia. Hearing aids are a public health issue.

France has 6 million people with hearing loss, i.e. 10% of its population. When talking about hearing disorders, it is essential to distinguish between presbycusis and hearing handicap. Presbycusis concerns 88% of the hearing impaired population, while hearing handicap affects 12% of this population, i.e. a little more than 700,000 French people who practice sign language and lip reading. Among people with a hearing handicap, there are :

  • People with severe deafness (any hearing loss between 80dB and 90dB). They represent 9% of people with hearing disabilities ;
  • People with profound hearing loss (any hearing loss above 90dB). They represent about 3% of people with hearing loss.

The percentage of people who are fitted with hearing aids varies according to the severity of the hearing loss and the possibility - or not - of fitting a hearing aid. For example :

  • Profound deafness cannot be fitted with a hearing aid : the individuals practice sign language ;
  • Severe deafness can be fitted with a hearing aid and 90% of the individuals concerned are fitted with a hearing aid, after a long and regulated care pathway. Without this hearing aid, they would not have been able to acquire language or socialize. Many of them also practice sign language or even lip reading. For these people, hearing aids are essential ;
  • Mild to moderate hearing loss, presbycusis, can be fitted. However, only 25% of those affected wear a hearing aid, i.e. 1 out of 4 people. Presbycusisers are directly concerned by the risks link to not wearing a hearing aid, because they are the only ones who refuse to wear one, considering their hearing problem to be a simple inconvenience and not wanting a heavy, visible or expensive solution to compensate for this discomfort.

For people with a hearing handicap, the care pathway to hearing aids is long and regulated. The first step is to identify the disability : deafness is not the main reason to think about when a child is isolated, speaks little, or does not understand. Many doctors are consulted. One of them realizes that the problem is auditory and refers the parents to an ENT specialist, who will confirm the handicap. If the problem can be corrected, the patient is then referred to a hearing aid specialist.

"My deafness started at birth, I grew up in a hearing environment but I couldn't hear properly I was treated in psych while I was hearing impaired. I lost my left ear when I was 4 years old and with my mother I used a very personal code to communicate. It was only at the age of 28 that a psychiatrist had doubts about certain behaviours I was having, which could be the consequence of a deafness and/or a neurological disease. I was not able to buy my hearing aids until I was 45 years old. It was at that age that the neurological disease was discovered: mitochondrial myopathy type SKK."

The second step is to fit the hearing handicap with a hearing aid (BTE) and to adjust the hearing aid. The adjustments and their follow-up, in time, for this type of deafness, are essential : it is about individuals who will learn to hear, with hearing aids. All sounds are different and the job of a acoustician is to make them as pleasant as possible for the person fitted with the hearing aid. This is a long and delicate job, which guarantees a good quality of life for the hearing handicap person.

"With my hearing aids, what I hear is metallic and distorted, unpleasant. Without a hearing aid, I can hear some of what I heard before my hearing problems, but I miss the extreme frequencies."

--

"I never really heard music without a hearing aid. I know the sounds are different, but I can't make a personal comparison."

--

"Listening to music with my hearing aids is horrible, impossible to bear. I used to love music, I was in a choir. I am unable to recognize a tune, or a song and the musical sound has come a torment."

--

"I am profoundly deaf with tinnitus and vertigo, as a result of shell and grenade explosions suffered on January 18, 1959 and a skull injury on November 9, 1960. My perception of music is totally different from what it was before this date. Very painful existence since these disabling injuries which are heavy to bear."

The care pathway and the offer of hearing aids for prebyacousics are, today, the same as those offered to people with handicap :

  • A long and regulated pathway ;
  • A BTE hearing aid in 80% of cases ;
  • A 4-year follow-up service, which is rarely used by the concerned people.

The only difference is the coverage : excellent for people with hearing handicap but very poor for presbycusis.

As a result, people with presbycusis either reject the care pathway or accept it to a certain extent : the pathway to hearing aids has many dropouts at different stages.

People with hearing handicap - just over 700,000 in France - practice sign language and lip reading. Their hearing loss is such that without hearing aids, they would not be able to socialize. Their disability must first be detected and then requires - when possible - a complex hearing solution (which can go as far as a cochlear implant), with numerous adjustments and settings, on atypical audiometric curves. The importance of these hearing losses (greater than 80dB) and the uniqueness of these audiometric curves make :

  • Pre-fitted hearing aids impossible for these individuals, custom fitting is a necessity ;
  • Follow-up over time and adjustment of hearing aid settings essential. Learning or relearning to hear requires regular adjustment according to the user's feelings and the technical possibilities of the hearing aid.

Orison is a hearing aid whose pre-configuration has been exclusively designed to compensate for presbycusis, which is a classic hearing loss, on specific frequencies. Orison compensates for mild to moderate hearing discomfort, below 80dB, i.e. all hearing discomfort that is not a hearing handicap. In fact, a person with a hearing handicap would not notice any difference by wearing Orison, whereas a person with presbycusis would find it immediately comfortable.

• With an ENT audiogram

If you have an audiogram from an ENT doctor, make sure that your left and right audiometric curves are in the green space below. To do this, simply plot the x-axis and y-axis of your audiometric curve on the graph below. The green space is the boundary of all hearing losses compensated by the Orison ITE hearing aid.

• Without an ENT audiogram

If you don't have an audiogram, try it. Orison is available over-the-counter and is 20-days money-back guarantee.

SERINITI has implemented the "Satisfied or 20-days money-back guarantee" for all purchases of hearing aids made on the website www.www.seriniti.fr or by mail order, directly from SERINITI. Therefore, if - for any reason - the digital CIC Orison hearing aid does not suit you, you have 20 days to return it, in its original box, with all accessories and components, in accordance with our General Terms of Sale. Upon receipt, your order will be sent to the Technical Department to check its perfect functioning and will be refunded within 3 to 5 days. Full details of the "20-days money-back guarantee" are available in our Terms and Conditions.

No. The digital CIC Orison hearing aid  is an over-the-counter hearing aid, so you do not need a medical prescription and you are not required to consult an ENT doctor before purchasing Orison. However, we recommend that you consult a doctor if any of the following situations apply to you :

  • Your hearing discomfort has come on suddenly ;
  • Your hearing discomfort occurs intermittently ;
  • Your hearing loss affects only one ear ;
  • Your hearing loss is accompanied by severe headaches or even dizziness.

Simply because the morphology of the ear canal requires it, for greater comfort in use. Each hearing aid respects the shape of the ear canal for which it is intended. The international codes in this area are as follows :

  • Red = Right, for the right ear,
  • Blue for the left ear.

No. You can opt for a unilateral hearing equipment. There are several things to consider when answering this question :

  • The hearing loss,
  • The user's needs,
  • The type of hearing aid.

On the other hand, it is important to keep in mind that the role of a hearing aid is to amplify the sound stimulus diminished by the hearing loss, so that it remains strong enough to stimulate the central nervous system. This stimulation can come from the right or the left ear, it does not matter. Hearing aids, whether unilateral or bilateral, are more about the user's comfort.

• Hearing loss

Presbycusis is bilateral and symmetrical, which means that it affects both ears in the same way (see "What is presbycusis ?"). Thus, bilateral hearing aids are naturally recommended. Generally speaking, it is considered that hearing aids are recommended from a hearing loss of 30dB. As the body is never symmetrical in reality, it is not uncommon for one ear to have a hearing loss of 30dB or more and the other ear not. In this case, a unilateral fitting (on one ear only) is sufficient and should be done on the ear with the greatest hearing loss (equal to or greater than 30dB). If you do not have an ENT audiogram, the ear concerned is generally the one that you do not "stretch" when you are spoken to, unconsciously relying on the other.

• The needs of the user

The unilateral hearing aid is also sufficient if the hearing discomfort is incipient (we speak of primo-presbycusis), punctual (in front of the television, in a restaurant, with friends) and you only plan to use Orison at these moments, to begin with. On the other hand, if you firmly reject hearing aids, we recommend that you opt for a unilateral hearing aid, even if you only wear it once in a while, the ideal being to gradually get used to the amplification of a hearing aid.

• The type of hearing aid

The possibility of a unilateral hearing aid is real with an ITE hearing aid (such as Orison), less with a BTE hearing aid. Indeed, an in-the-ear hearing aid, by its position, uses the natural capacities of the ear, anatomical amplifier. Thus, thanks to the use of the pinna and the proximity of the tympanic membrane, Orison reproduces amplified sounds without delay : this means that there is no difference between the ear fitted and the one that is not, which allows a consequent hearing comfort, even with a unilateral fitting.

• You have an audiogram performed by an ENT doctor

The audiogram shows the hearing loss in each ear. This hearing loss is expressed by a point which relates (abscissa, ordinate) frequency and amplitude. The set of points forms the audiometric curve. On an audiogram, the right ear is on the left and the left ear is on the right, as the ears appear to the doctor who is running the audiogram. Choose to fit the ear in which your audiogram shows a hearing loss of 30dB or more (see "What is presbycusis?").

• You do not have an ENT audiogram

As Orison is available over the counter, it is quite possible that you do not have an ENT audiogram. If so, try it. Orison is "Money Back Guarantee" for 20 days. If you choose a one-sided fitting, focus on :

  • The ear that you do not "stretch" when you are spoken to, i.e. the one on which, unconsciously, you do not bet ;
  • If you have tinnitus in one ear, fit an instrument in that ear. If you have tinnitus in one ear, get that ear fitted. It is considered that hearing aids, by amplifying voices, tend to mask tinnitus naturally.

No. This is a question we are regularly asked and it never ceases to surprise us. It is a sign of misinformation about hearing disorders. The aging of the auditory system is linked to the destruction of the hair cells of the ear. Unlike the eye, which rests for about a third of our lives (as soon as the eyelid closes), the ear is never at rest and begins to age from birth. Noise, repeated sound aggression, the practice of certain sports that can cause sound and/or pressure trauma, the taking of certain medications, a poor lifestyle (diet, smoking) are the main causes of the aging of the ear and the appearance of hearing loss. To preserve your hearing, it is essential to protect yourself from noise and to adopt a healthy diet (see "How to prevent presbycusis ?") A hearing aid is not intended to prevent the ageing of the ear, but to provide listening comfort when discomfort is present.

  • Can hearing loss be prevented ?

In hearing aids for presbycusis, the user has the choice between an ITE hearing aid (slipped into the ear canal) and a BTE hearing aid (placed on the ear). To help the user make an informed choice, we have written  comprehensive articles on the subject, available in "Further informations area".

  • Hearing aids... an ancient history !
  • Hearing aid: In-the-canal VS Behind-the-Ear, what should I choose ?

There are no contraindications to wearing an in-the-ear (ITE / CIC) hearing aid like Orison. There may, however, be some impossibilities :

  • If the ear canal is very small, Orison will perform its role perfectly, however it may "protrude" significantly from the ear and be visible. Thus, although the listening comfort will be there, the result will be unaesthetic : we prefer to orient people with very small ear canals on devices of the BTE type ;
  • If the ear canal is very large, no earmold size (S, M or L) or type (CONE or TULIPE) will ensure occlusion of the ear canal. Thus, even if the device will be perfectly invisible in the ear, it will whistle permanently because the eartip will not play its role. We advise people with particularly large ear canals to use custom-made intra-ductal devices (moulding of the ear canal) by a hearing care professional.

The number of people affected (very small ear canals or very large ear canals) is relatively small : since 2016, we have only seen about ten individuals in either situation.

Yes, because of its in-the-canal (ITE / CIC) position, the digital instant-fit CIC Orison uses the ear. Composed of the pinna, which captures and spatializes sounds thanks to its funnel shape and folds, and the ear canal, which guides them to the eardrum, the ear is the most efficient natural amplifier. Slipped into the ear canal, the Orison hearing aid uses the ear, allowing it to :

  • Locate sounds in space ;
  • To reproduce sounds in a natural way ;
  • To reproduce sounds without delay ;
  • To benefit from a spatial field of 180° for a unilateral fitting and 360° for a bilateral fitting.

A pre-adjusted hearing aid is commonly referred to as a "sound amplifier" or "listening assistant" while a hearing aid adjusted by the hearing care professional to the patient's audiometric curve is commonly referred to as a "hearing aid", "hearing prosthesis". What do these two types of hearing aids really have in common and what are the differences ?

• Common point : their nature

Pre-adjusted or custom-made, a hearing aid is, by its very nature, a sound amplifier ! Indeed, as we mentioned earlier, when the hair cells of the ear are destroyed, they do not grow back and the only solution available to the hearing impaired person is a hearing aid. To date, hearing aids do not incorporate any artificial intelligence and do not regrow the destroyed hair cells: whatever its price, a hearing aid is an imperfect acoustic solution, which amplifies sounds on different frequencies.

• Common point : their name

The French National Agency for Health and Medicines (ANSM) specifies that terms such as "listening assistant","sound amplifier", " hearing device", " hearing aid", "hearing prosthesis", "hearing assistant" or "external hearing aid" do not describe the purpose of the product and do not interfere with its regulatory status. Pre-adjusted or not, sold online or at a hearing care professional, a "sound amplifier" is therefore a "hearing aid", a "hearing aid", a " hearing aid " or even a "hearing device".

• Common point : their pre-configuration

All hearing aids, whether pre-set or not, have a certain number of frequency channels pre-configured by the manufacturer, on which the intrinsic automatisms of the hearing aid are based. In the case of a hearing aid such as Orison, the pre-configuration has been carried out by doctors in order to compensate for the frequencies that are affected by the natural aging of the ear (presbycusis). In the case of a hearing aid marketed by a hearing care professional, certain frequency channels (3, 6, 9 or more) are left free to the seller, in order to adjust the settings on the patient's audiogram.

• Common point : technical characteristics and electronic components

Number of frequency channels, HD digital processor, intelligent sound signal processing, ambient noise reduction : the Orison hearing aid has similar technical features to much more expensive hearing aids. It also has the CE standard, a guarantee of quality in a market where the offer starts at less than 10€ and goes up to more than 5000€.

• Difference : who they are for

Pre-configured hearing aids such as Orison are aimed exclusively at people with presbycusis, i.e. people who, over time, experience daily, occasional or continuous hearing loss, particularly in noisy environments or in front of the television. These people need a hearing aid that is easy to use, with fine tuning to the affected frequencies, as well as a significant reduction in ambient noise, in order to regain immediate listening comfort. A person with a hearing handicap (who speaks sign language and/or lip-reading) will not feel any difference by wearing Orison : he or she needs a much more consistent amplification, on an atypical audiogram, as well as regular follow-up over time, allowing him or her to adapt to the hearing aid but also to adjust it to his or her feelings. Thus, if the pre-adjusted hearing aid is aimed at individuals experiencing a simple hearing discomfort, the custom hearing aid is aimed more at those who could not socialize without a hearing aid (90% of them are fitted).

• Difference : the price

In September 2015, UFC Que Choisir published a study entitled "Audioprothèses, un marché verrouillé au détriment des malentendants" (Hearing aids, a locked market to the detriment of the hearing impaired), in which it is pointed out that the follow-up service, over 4 or 5 years, represents 40% of the total cost of traditional hearing aids. While this service is essential for a person with a hearing impairment, it is not for a person with presbycusis : the same study emphasizes that few presbycusis users make use of their follow-up service, for various reasons (they do not wear their hearing aid, they do not feel the need for follow-up, the hearing aid specialist has closed down, the user has passed away, etc.). A pre-adjusted hearing aid such as the Orison is sold without a follow-up service, relying on the user being perfectly autonomous.

• Difference : the adjustment

While a pre-configured hearing aid has a setting specifically designed to compensate for presbycusis and is therefore suitable for millions of individuals in France and around the world, a custom hearing aid is, by definition, adjusted to the audiometric curve of the hearing impaired person fitted and can therefore only be suitable for that person.

• Difference : the distribution network

Available without a medical prescription, a pre-adjusted hearing aid such as Orison can be sold anywhere (internet, pharmacists, opticians, department stores, electronics stores, paramedical stores, etc.). A custom-made hearing aid, on the other hand, can only be delivered with a medical prescription in order to be covered by Social Security and can only be sold and adjusted by a hearing aid specialist.

  • An American study overturns preconceived ideas about hearing aids for presbycusis

The production cost of a hearing aid is relatively low. As a general rule, the cost of raw materials and components is around 50€ per unit ; the final production cost is between 80€ and 250€, depending on the device's features. Throughout the resale chain (manufacturer, wholesaler, hearing care professional, final consumer), the price is subject to increases. For a mid-range custom hearing aid sold at 1,550€ per ear to the final consumer (a device that accounted for 80% of hearing aid sales in 2015), the final price is 5 times more expensive than the production cost.

Price differences between a custom-made hearing aid and a pre-set hearing aid such as Orison :

Composition of the selling price of a custom-made hearing aidComposition of the selling price of a pre-fitted hearing aid
Before buying
  • Medical consultation
The traditional hearing aid must be prescribed by a doctor, and the patient must visit a doctor (ENT or general practitioner). The rate of the consultation is variable (sector 1 or sector 2). For each medical consultation, the social security pays 23€ (France reference).
At the time of purchase
  • Price of the hearing aid + adjustments of the device + follow-up over 4 to 5 years

The additional follow-up services are estimated at 8 hours of labour over 5 years for a bilateral hearing aid. They represent 40% of the total cost of the hearing aid and are mandatory to qualify for social security coverage.

No, Orison is not rechargeable. There are 4 reasons for this :

  • Rechargeable technology takes up space. So far, it is mainly available on BTE and ITE hearing aids. We want Orison to remain small and discreet ;
  • Rechargeable technology is not up to speed in terms of autonomy. The hearing aid needs to be recharged every night, whereas a Rayovac Proline battery gives your Orison hearing aid up to 6 days of life ;
  • Rechargeable technology decreases with use and can lose 10% to 20% of its capacity in the first year of use ;
  • Rechargeable technology has a cost : we do not want to increase the price of Orison.

Not all hearing aids are the same : don't let the user think that the outer shell of the hearing aid... is the hearing aid ! The quality of a hearing aid is linked to :

  • The on-board electronic components and in particular the microphone (which picks up sound) and the processor (which processes it). Orison's on-board components are European. You will find similar components on much more expensive hearing aids. Orison is also CE certified ;
  • The quality of the pre-setting of the device. Orison's amplification has been developed by doctors and engineers. To this end, over 150,000 audiometric curves were initially synthesized into 7 separate amplification programs. These programs were then tested for more than half a year so that only one was selected and then refined over the next half year and before going into production. Since 2016, Orison has thus undergone three major evolutions of its amplification, allowing it today to enjoy the success it does.

Regarding the external shell of the Orison hearing aid, it is - like all external shells of hearing aids, whether they are sold at 10€ or over 2,000€ - produced in Hong Kong, in biomedical plastic. There are only two manufacturers of hearing aid shells in the region, which explains the similarity between many hearing aids, even though their selling price or technical characteristics differ widely.

No. As Orison is an in-the-ear hearing aid, it is positioned in the ear canal. So it won't get in the way, whether you wear short hair, glasses or a COVID mask.
