I accidentally came across an interesting and useful test on the Internet - online hearing test.

It’s sad, but it’s a fact - we are all not getting any younger, but quite the opposite. As we age, our hearing deteriorates—for some, more, and for others, just a little. For some, this sad process happens quickly, but for most people it is very slow and completely unnoticeable.

This is why periodic hearing testing is imperative. You can (and should) go to the doctor every year, but which of us, feeling healthy, goes to him?

I really hope it’s simple and quick test the hearing test, which is located at the end of the article, will make you worry about your health before it’s too late.

This test consists of five stages. The first is just an introduction, at which you need to click on the “Continue” button, and the last (fifth stage) is the verdict itself.

The second stage of the online hearing test is calibration. You need to use the slider to set what will be on the right, the sound level you can barely hear...

During the test itself, you will no longer be able to change it.

The third stage is again practically useless - short instructions for people with very low level intelligence. It tells you that when you hear a sound, you need to press the “I hear” button, and when you don’t hear it, you need to press “No”...

And finally, the fourth stage - the test itself or an online hearing test...

...after completing it you will be shown the result...

I also changed the size of the window, which caused the font to be slightly distorted - I apologize wildly, but otherwise the test simply would not have fit on the page.

It seems like he told and explained everything - proceed to the online hearing test...

Online hearing test

This test must be taken in complete silence, or even better - in good headphones.

Get started...

That's all online hearing testing is all about. I really hope that your test result is the same as mine. Until new useful ones computer programs and advice.

Hearing testing is carried out by 2 main groups of methods: objective and subjective. Objective methods are based on the occurrence unconditioned reflexes. Subjective methods include acoustic and audiometric methods.

Hearing assessment methods

Objective methods of hearing research do not require the direct active participation of the patient and are more often used in pediatric practice (in newborns and children under 3 years of age).

All newborn children undergo audio screening - the study of hearing by recording otoacoustic emissions.

An objective hearing test is used:

• For diagnosis in disabled people, patients in a comatose state;
• To solve controversial issues examination and rehabilitation.

The acoustic method includes examination of hearing using spoken and whispered speech, and examination with tuning forks. The audiometric method is a hearing test using an audiometer. In the practice of an otorhinolaryngologist, both of these methods are used.

Indications for ear examination

Rumor in mandatory checked during medical examinations of workers employed in noisy industries. The test is carried out first by the acoustic method, and then by the audiometric method.

Hearing is required to be checked by the driver's commission.

In pediatric practice, if there are no hearing complaints, the doctor checks the child’s hearing when registering for kindergarten and school. If a patient (adult or child) complains of ear pain, congestion, or hearing loss, an otolaryngologist will conduct a hearing test before and after prescribing treatment.

Diagnosis of eardrums

Let’s imagine a situation: a person came to see an ENT doctor complaining of hearing loss. The doctor collected anamnesis, identified complaints, and performed an examination.

If there are no foreign objects or wax plugs, which often cause hearing loss, the doctor begins to check the hearing analyzer.

Acoustic testing method

1. Spoken speech test. The doctor or nurse asks the patient to stand in a certain place in the office, cover one ear with a hand or cotton earplugs, turn toward the wall, or close his eyes. Why turn away or close your eyes? Many people, without knowing it, can “read” lips.

   For the study to be reliable, this “auxiliary” maneuver must be excluded. When the patient is ready, the doctor comes close and speaks numbers or words in a loud and clear voice. Words and numbers containing both voiced and voiceless consonants are used: cup of tea/cat/mouse and house/girl/frog.

   In children, phrases that are understandable to children are more often used, and in the study of adults, numbers are used. The doctor gradually steps back from the patient, continuing to speak until the distance between the doctor and the patient is 6 meters.

   Then the same procedure is repeated with the other ear. 6 meters is the minimum distance at which a healthy ear can hear spoken and whispered speech.

2. Whisper speech test. After preparing the patient (the same as when testing spoken language), the doctor or nurse pronounces phrases and numbers in a loud, clear whisper, gradually moving away from the person being tested until the distance between them reaches 6 meters.

   If the person being tested has hearing colloquial speech 6:6 and in whispered speech 6:6 - he is absolutely healthy in hearing and can be hired for any job, even in noisy production. If the hearing is impaired, and at least one ear can hear at a distance of less than 3 meters, such a patient cannot be allowed to work in noisy production and at heights.

   When testing children, especially preschoolers, it is advisable to pronounce phrases that are familiar to them: names of animals, names fairy-tale heroes. You can not say a word, but ask your child a question that requires an answer, for example: “do you like candy?” etc. (joking check).

3. Tuning fork tests. Testing with tuning forks is not usually used for preventive examinations, and when dealing with complaints of unilateral or bilateral hearing loss. A tuning fork is a musical instrument that produces a clear sound of a certain frequency.

   In medicine, tuning forks with a sound frequency of 128 (C128) and 2048 (C2048) per second are mainly used. 3 tuning fork tests are used: Weber, Rinne, Schwabach.

Audiometric test method

Testing on the device is carried out using an audiometer. The device generates a sound signal of varying intensity (from 0 to 120 dB) at different frequencies (from 125 Hz to 8000 kHz).

First, air conduction is checked, then bone conduction. The hearing threshold is considered to be the perception of a signal with an intensity of 10 dB at a frequency of 125 Hz.

How is audiometry performed? First, air conductivity is checked - the person being tested is put on headphones and a sound signal of the same intensity at different frequencies is sent to each ear separately, then the intensity increases.

As soon as the patient hears a sound, even the quietest one, he presses the button. The signal is recorded by the audiometer operator and transferred to the audiometric form. Air conduction is recorded for each ear separately.

Then bone conductivity is measured - mastoid(behind the ear) a special bone microphone is installed, the principle of signal transmission is the same as when measuring air conductivity. Bone conduction is usually lower than air conduction, and there is a small interval between them on the audiogram.

In children's practice, audiometers are sometimes used that produce not just a sound signal, but a word specific for each frequency, constantly increasing the intensity of the sound.

Why does hearing decrease in diseases?

Hearing loss with various diseases can be reversible and irreversible. Reversible changes are most often associated with inflammation of the cells of the outer, middle or inner ear, inflammation and narrowing of the auditory tube.

Irreversible changes are associated with the death of cells of the receptor apparatus or the auditory zone of the cerebral cortex.

The causes of hearing impairment can be divided into 2 large groups:

• Violation of sound transmission;
• Impaired sound perception.

Violation of sound conduction is associated with diseases of the sound-conducting apparatus:

• External auditory canal ( otitis externa, sulfur plug, foreign bodies of the auditory canal);
• Middle ear (acute and chronic otitis media, exudative otitis media, tubootitis, myringitis);
• Inner ear (labyrinthitis).

In these diseases, hearing is reduced due to the fact that sound does not travel properly through the ear canal, is not perceived by the eardrum, and is not amplified by the circuit. auditory ossicles etc. Hearing changes due to sound conduction disorders are often reversible and disappear after proper treatment.

Sound perception impairment is more complex pathology, By various reasons the functioning of the receptor apparatus of the inner ear and/or the auditory zone of the cerebral cortex suffers.

Such changes are caused by:

1. Trauma: traumatic brain injury, pyramidal fracture temporal bone, barotrauma;
2. Infectious disease, especially in children: influenza, measles, rubella, tick-borne encephalitis;
3. Taking ototoxic drugs: gentamicin, other aminoglycosides;
4. Dysmetabolic disorders: microangiopathy in diabetes mellitus;
5. Age-related changes: as a result of atherosclerotic damage to the vessels of the head and neck, the blood supply to the inner ear suffers and senile hearing loss develops.

Hearing loss due to impaired sound perception is sometimes curable, but requires longer and more persistent treatment with specific drugs:

• Neuro- and angioprotectors;
• Preparations that improve tissue trophism;
• Histamine receptor blockers.

How to test your hearing for the effectiveness of treatment

Improving hearing as a criterion for recovery can be taken into account in the treatment of diseases of the sound-conducting apparatus (otitis media/myringitis, etc.).

The course of treatment is usually 7-10-14 days, rarely more. And in case of recovery, the patient himself notes an improvement in hearing.

If the sound-receiving apparatus is damaged, reliable criterion The effectiveness of treatment is considered to be an improvement in hearing (according to the results of acumetry and audiometry) with repeated studies after 3 months of taking the prescribed medications.

Possible consequences of hearing loss

A disease associated with hearing impairment is medically called hearing loss. It may vary in severity and cause. Hearing loss is temporary or permanent. It may be curable or progressive. Depending on the severity of the hearing loss and when it occurs, the impact on the patient's life will vary.

It is most difficult to determine hearing loss in a child. More often it manifests itself in the fact that there is no reaction to loud sounds. The child does not lose hearing completely, but he or she may not be able to hear part of the sound spectrum. This situation leads to slow development of speech. The child speaks poorly and has a small vocabulary, does not respond to requests from adults.

If hearing loss is not treated for a long time, then destructive processes occur in the cerebral cortex. Gradually, the area responsible for hearing begins to decrease in size and completely atrophies. It is no longer possible to restore brain function to its original state.

IN school age this leads to problems during training. Children with moderate and severe hearing loss are forced to study in schools. They are less adapted to independent life. Light form hearing loss often characterizes patients as inattentive, distracted individuals. It is often said about them that they only hear what they want. Every day is stressful for them; they have to listen to every word in order to get the full amount of information.

The most pronounced consequences are moderate and severe hearing loss, which cannot be treated or progress to running form. With moderate severity of the disease, a person tries to take a defensive position, he participates less in public life, begins to gradually isolate. In conversations, the patient either dominates or tries to avoid it.

The more severe your hearing loss becomes, the more difficult it is to hide it from others. In the absence of treatment, the patient limits social contacts and avoids public events. Distrust and hostility towards the world around us leads to paranoia and isolation. Sometimes aggression and anger towards loved ones manifests itself.

In cases of severe hearing loss and the absence of treatment for the disease, among the consequences are: complete destruction social life, alcoholism, drug addiction, as an attempt to escape from the surrounding reality. Ultimately, the patient faces a transition to the “deaf” world. If hearing problems are detected, it is necessary to promptly diagnose and begin treatment.

How much does a hearing test cost?

Diagnosis of hearing loss can be carried out in a city clinic according to the medical pole or in paid center. In the first case, the procedure will be free, but it may not meet the requirements of a particular situation.

In a paid center it is possible to conduct more than wide range research.

1. An examination by an ENT doctor is the first stage in identifying hearing problems. The doctor examines the auricle and examines the eardrum for damage. Conducts speech research. The cost of an appointment with a doctor, depending on the medical center, ranges from 1000 to 1500 rubles.
2. Study with tuning forks. This examination is necessary to detect air and bone conduction. A set of tuning forks with different tones is used for the study. The method is more subjective and depends entirely on the professionalism of the doctor. Its cost is about 500 rubles.
3. To determine the volume that a person hears, it is necessary to conduct speech audiometry. The study is carried out in a soundproof room. All results are recorded on tape. The cost is about 1000 rubles.
4. In serious cases where brain dysfunction is possible, an MRI is necessary. The cost of the examination is about 2000 rubles.
5. Electrocochleography is required to diagnose cochlear and auditory nerve activity. The cost is from 1200 rubles.

Price paid services Diagnosis of hearing loss will be different in different medical centers. Lowest prices in government institutions providing paid services.

Where can you quickly and accurately check your hearing?

The very first hearing test is carried out on a newborn. postpartum department. If the first test was successful, but parents have doubts about the baby’s hearing, it is necessary to contact an ENT doctor in city ​​clinic. The doctor will conduct an examination and carry out the necessary studies.

If there are suspicions of serious abnormalities, he can issue a referral to specialized research institutes. There are 2 centers in Moscow.

1. NCC of Otorhinolaryngology. Located on Volokolamsk highway. The center turns out to be all kinds medical care for ENT diseases. The structure of the complex includes laboratories, research centers, clinic. We employ specialists of a wide range of profiles. At the NCC you can get advice, carry out full examination, implement surgery.
2. Research Institute of Pediatrics. Science Center Children's Health RAMS is a broad-spectrum structure. It includes a clinic, a hospital, and a scientific department. The main task of the research institute is to provide medical care in all main areas.

All studies related to hearing loss can be carried out in paid diagnostic centers. There are these in every city. Main role It is not the name of the clinic that matters, but the training and professionalism of the doctor who will perform the procedure.

What does a hearing test tell you?

Hearing testing may be required at different ages.

Timely implementation diagnostic studies gives its results.

1. In case of acute hearing loss, diagnosis is carried out in a hospital setting. There's an emergency there too complex treatment. More often it is antihistamines, antibiotics, ear drops. Treatment is aimed at restoring hearing and eliminating the inflammatory focus.
2. At frequent illnesses in children, especially if they are associated with the growth of adenoids, diagnosis is necessary to identify hearing impairment. The appearance of hearing loss is a direct indicator for surgical intervention.
3. Diagnosis of hearing loss caused by infectious diseases, allows you to completely eliminate the source of infection and provide adequate treatment. Timely assistance prevents the progression of the disease. Hearing is restored completely.
4. In case of abnormalities in the development of hearing organs, timely diagnosis allows timely action to be taken. In some situations, surgical intervention or installation of hearing aids is possible. Such an adjustment will allow the child to hear the entire spectrum of sounds, therefore, his speech and all parts of the brain will develop harmoniously.

Without diagnosis, hearing loss will gradually progress, which will lead to irreparable consequences in the patient’s life.

The topic of audio is worth talking about human hearing in a little more detail. How subjective is our perception? Is it possible to have your hearing tested? Today you will learn the easiest way to find out whether your hearing fully corresponds to the table values.

It is known that the average person is able to perceive acoustic waves with the organs of hearing in the range from 16 to 20,000 Hz (depending on the source - 16,000 Hz). This range is called the audible range.

»
This test is enough to give you a rough estimate, but if you can't hear sounds above 15 kHz, you should see a doctor.

Please note that there is an audibility problem low frequencies, most likely related to .

Most often, the inscription on the box in the style of “Reproducible range: 1–25,000 Hz” is not even marketing, but an outright lie on the part of the manufacturer.

Unfortunately, companies are not required to certify all audio systems, so it is almost impossible to prove that this is a lie. Speakers or headphones may reproduce boundary frequencies... The question is how and at what volume.

Spectrum issues above 15 kHz are a fairly common age-related phenomenon that users are likely to encounter. But 20 kHz (the same ones that audiophiles fight so hard for) is usually heard only by children under 8–10 years old.

It is enough to listen to all files sequentially. For a more detailed study, you can play samples, starting with the minimum volume, gradually increasing it. This will allow you to get a more correct result if your hearing is already slightly damaged (remember that in order to perceive some frequencies it is necessary to exceed a certain threshold value, which, as it were, opens and helps the hearing aid to hear it).

And you hear everything frequency range who is capable?

The human hearing organ has a complex and at the same time unique structure. So, the ears are responsible for many important functions in the structure of man. First of all, the human hearing organ is necessary for the receptivity of sounds, their processing and conversion into decibels, and then sending them to the brain. In addition, the ear is responsible for human balance.

In case of dysfunction of any department, a person experiences ear pain and headaches, loss of hearing acuity, a feeling of congestion, and others. unpleasant symptoms, which can knock a person out of his usual way of life for a long time. In order to test the sensitivity of sounds, there are hearing testing programs.

Not all people can notice immediate hearing loss. In most cases, sound sensitivity occurs gradually. At this time, a person loses the ability to hear the lowest sounds. To determine the sensitivity of your hearing, you can take a hearing test online or contact a medical center.

However, a person pays attention to minor changes in the ear organ only after a hearing test. But truly human begins to worry only when he notices that the range of audibility has noticeably changed. Usually at this time a person cannot understand a whisper from an arm’s length distance or feels a problem understanding speech on TV or on the radio.

Cause hearing impairment lies in dysfunction middle region organ of hearing. The middle region is located after the outer part of the ear organ and in front of the inner ear. The middle region does not have a complex, but exceptional structure, and thanks to its work, a person perceives both the highest and low-frequency sounds.

Besides this, this part distinguishes and enhances signals, intonations and various noises.

In general, the following elements are responsible for the operation and transmission of sounds:

1. Outdoor area. It includes auricle and external auditory canal. It is separated from the middle region of the hearing organ by the eardrum.
2. Middle ear. After the eardrum there is the middle ear, the Eustachian tube and the auditory ossicles.
3. Interior has one of the most unusual structures in the human body. The second name of the described area is a labyrinth. The main task of the labyrinth is to maintain human balance.

IN anatomy ear includes the following elements:

• curl;
• antihelix;
• antitragus;
• earlobe.

Due to their complex and unique structure, they rarely enter the hearing organ. various bacteria and infections, and external factors cannot affect human health.

Therefore, almost all ear diseases occur during periods of weak immune system or as a result of the penetration of viruses through the nasopharynx.

The structure of the middle part of the hearing organ

As we have already found out, the reason for decreased hearing acuity and other inflammations lies in a disease of the middle part of the ear. Before identifying the reasons, let’s understand the structure of this element.

Everyone knows that the middle ear is located behind the eardrum and is located near the temporal part. In the depths temporal region the following are located parts of the middle ear:

1. The mastoid process is located in the temporal bone. It connects the tympanic and temporal parts.
2. Between the temporal region and the external auditory canal is tympanic cavity.
3. This area connects to the nasopharynx using eustachian tube. Its functions include pressure regulation.

These three elements have numerous functions and additional structures.

So, the main area of ​​the middle ear is tympanic cavity. Its structure includes the following components:

1. TO eardrum the hammer is adjacent. He transmits the received sound waves further to the auditory ossicles.
2. The second component of the ossicles is the anvil. It is located after the malleus, but before the stirrup. The main function of this bone is to transmit sound vibrations further in direction.
3. The stapes covers the auditory ossicles. Its function is to transmit sound vibrations to inner ear, and then to the brain. Interestingly, this area is considered the lightest bone not only in the ears, but in the entire body. Its size is about four millimeters and its weight is 2.5 mg.

All of the above elements convert sound waves or noise and transmit the processed sounds further to the internal part.

If one bone is damaged, dysfunction of the entire section occurs, and as a result, loss of hearing acuity.

Besides this, The tasks of the auditory ossicles include:

1. Maintaining eardrum function.
2. Adjusts and reduces very high sounds.
3. Adaptation of the ear to perception different sounds in height and strength.

You should visit an ear doctor twice a year. This way you can avoid many types of inflammation.

There are special sounds for hearing testing. When examined by an ENT doctor, do not forget to undergo a hearing acuity test.

Hearing impairment is one of the main signs indicating pathological processes occurring in the ear. It is important to note the appearance of this symptom in time and contact an otolaryngologist for advice, because many diseases require qualified and timely treatment, and delay in therapy can lead to hearing loss. What hearing testing methods are there? Is it possible to diagnose it yourself?

Classifications of pathology and its causes

The general term “hearing loss” is classified by specialists into several groups.

According to the prognosis, hearing loss may be:

1. reversible, that is, temporary. The most common cause of such hearing loss is inflammatory processes in the ear or auditory tube;
2. irreversible. Such hearing impairments occur due to the loss of receptors during inner ear, irreparable damage auditory nerves or pathologies of the cerebral cortex, which is responsible for receiving sound information.

Hearing loss can also be divided into 2 groups, based on the cause that caused this disorder.

Sound conduction disorder

Pathologies of this group are localized in the parts of the hearing organ - the outer, middle and inner ear. Sound vibrations from external environment do not reach the brain due to the fact that in one of the areas of the hearing organ a certain disease or condition does not allow them to pass along the chain:

1. in the outer ear such diseases and conditions may include otitis media, foreign body in the ear canal, cerumen plug;
2. in the middle ear, sharp, exudative and chronic otitis, myringitis and tubootitis;
3. In the inner ear, labyrinthitis can lead to disruption of sound transmission.

In case of sound conduction disorders, hearing loss is usually reversible, and with timely and qualified therapy, the functionality of the ear returns quite quickly.

Impaired sound perception

This group of diseases is considered quite dangerous and serious, most often such pathological processes are irreversible. Impaired sound perception is diagnosed if, during the course of research, a specialist determines that the sound-conducting functionality of the ear is not impaired, but by all indications it is clear that the work of the receptor apparatus is not performed properly.

The following can lead to disturbances in sound perception:

1. traumatic brain injury;
2. barotrauma;
3. temporal bone fracture;
4. infections (flu, measles, encephalitis, rubella);
5. taking ototoxic medications (gentamicin, aminoglycosides);
6. metabolic disorders in diabetes mellitus;
7. atherosclerosis of the vessels of the head and neck.

Why do you need to monitor your hearing acuity?

Regular hearing tests, especially after hearing loss inflammatory diseases, are extremely important for timely diagnosis pathological disorders.

Detecting hearing loss in optimal timing allows:

• extinguish inflammatory processes in time before they spread to neighboring areas of the hearing organ or tissue;
• stop the irreversible processes of hearing loss and take measures to adapt the patient to the outside world.

If you ignore this clear symptom, as hearing impairment, patients may be at risk total loss ear functionality.

Modern techniques

All hearing testing methods that are available to otolaryngologists can be divided into two large groups: objective and subjective.

Objective methods

Such methods are considered the most reliable, since their action is based on recording the occurrence of unconditioned reflexes during diagnosis.

Most often, objective methods are used in relation to children under three years of age. One of them is audiometry of newborns, which is carried out for every baby born within the walls of the maternity hospital. The study is carried out using special equipment that records the acoustic emission of each baby's ear.

Audiometry is used to study hearing acuity in disabled and comatose patients, as well as to provide an impartial picture in controversial cases.

Subjective methods

These methods of hearing testing are used by otolaryngologists when diagnosing the functionality of the ears in children over 3 years of age who can speak, as well as in adults during medical examinations, commissions, and when patients have complaints about a decrease in the acuity of sound perception.

Subjective methods are based on whispered speech and tuning fork tests, when the patient must either reproduce a quietly spoken phrase or confirm that he hears a sound. Such methods are actively used by otolaryngologists because of their simplicity, but at the same time, they do not provide such an accurate picture of the quality of sound perception of patients as objective audiometry.

Acoustic techniques

Acumetric techniques are used by otolaryngologists during medical examinations and commissions. This hearing diagnostic allows you to quickly assess whether the patient has problems with the perception of sounds.

Spoken speech test

The patient is asked to face away from the testing provider and cover one ear. The otolaryngologist comes close to him and loudly pronounces phrases containing voiced and voiceless consonants, and the test person repeats what he heard. Gradually the specialist steps back; ideally, the final distance between the inspector and the person being checked should be 6 meters.

Whisper speech test

Acumetry in whispered speech is carried out in the same way as in the case of spoken speech: the patient stands with his back to the doctor and closes one ear. The specialist begins to whisper phrases to the person being tested, gradually moving back until he reaches a minimum distance of 6 meters.

Tuning fork tests

Such hearing diagnostics are used if the patient has problems in sound perception during standard tests of spoken and whispered speech. Using this musical instrument The otolaryngologist will check which sounds the patient hears worst.

Audiometry

If standard tests show that the patient has hearing problems, audiometry is indicated. A special device checks the air and bone conduction of sounds in each ear and records all data in the audiogram field.

Hearing test at home

Unfortunately, not all of us undergo medical examinations and special commissions; many of us do not visit the otolaryngologist’s office for years. Meanwhile, we are constantly surrounded by noise, which can negatively affect the state of our hearing organs and even cause progressive irreversible hearing loss.

In order not to forever lose the ability to hear well, it is important to regularly visit an otolaryngologist and contact him for a hearing test and consultation at the slightest suspicion of deterioration in sound perception.

You can also pre-test your hearing at home. Experts have developed several simple techniques, which help determine whether a person has impaired functionality of his ears.

This type of hearing test is carried out in spacious rooms, protected as much as possible from extraneous noise. Two people must participate in the diagnosis - the subject who needs to test his hearing acuity, and the examiner.

1. At a distance of 2-3 meters from the subject, several phrases are whispered, which he must repeat.
2. Testing is carried out using whispered and spoken speech at a distance of 6 meters.

How to test your hearing at home alone? If you don't have a helper, listen to the sounds around you:

• you must recognize vibrations of different frequencies - from the low hum of appliances, to the high ticking of a clock and the singing of birds outside the window;
• you should not have problems with perception during telephone conversations;
• you should not constantly ask your interlocutors;
• your loved ones should not complain that you turn on the TV too loud;
• Don’t you think that most of your interlocutors speak indistinctly, unintelligibly and somehow quietly?

If any of the statements do not suit you, contact an otolaryngologist.

Hearing Test Apps

Another group of techniques for self-check hearing - special applications designed for mobile devices. With their help, hearing diagnostics is quick and easy.

1. uHear and Hörtest. These applications test each ear of the test subject in turn for the perception of different frequencies of sounds. The vibrations are transmitted through headphones, and the “patient”, having heard them, must press a button.
2. Mimi Hearing Test. Developed by the company that produces hearing aids. Testing is ideal for those who are looking for ways to test their hearing on their own. It takes place according to the standard scenario - through headphones sound vibrations are fed into the ear of the person being tested, and he must press the “Right”/”Left” buttons on the smartphone screen when he hears them. At the end of the diagnosis, the program displays your age as a result, which it determined based on the state of sound perception of your ears. If the numbers are incorrect, contact an otolaryngologist.
