If possible, contact your hearing aid more carefully and try to prevent strikes on him, or strong pressure. When replacing the batteries in your hearing aid, do it on a table or in a room with carpet on the floor.
After removing your hearing aid you should turn it off and remove the battery from the device. Then put the hearing aid in the case. Keep hearing aids in a safe place, away from children and animals, for preventing any damage.
Try not to heat your hearing aid and try not to drop it into the water. If you go to the pool or shower – do not forget to take off your hearing aid. You should remove your hearing aid before using a hair dryer or hair spray. Washing hearing aids is strictly prohibited. Don’t wipe them with alcohol, thinner etc.!
How to clean hearing aid:
As mentioned above, do not use water or other liquids for cleaning hearing aids, no matter what model of hearing aid you use. Take a soft, dry cloth and wipe your device using this tissue. When cleaning the hole out a hearing aid, microphone and vent holes, use special tools – brush and a special tool for cleaning, that you were supposed to be delivered with your device.
Accumulation of earwax-it is one of the most common problems in hearing aids. Even minimal accumulation of earwax in the ear canal can damage your device. Therefore, hearing aids, which are placed in the ear canal, as you know, should be cleaned more often than BTE Model hearing aids.
After removing your hearing aid from the ear, always pay attention on the accumulation of dirt on it, or earwax. You have to get used to clean a hearing aid as natural and familiar, as you brush your teeth in the morning
Mic hearing
If you brush intracanal hearing aids, use the short end, which is adapted to remove ear wax, to remove earwax that has accumulated near the entrance to the microphone on the battery compartment of your hearing aid. Open the battery compartment on your hearing aid and remove the battery. Expand the hearing aid so that the open battery compartment should be on the bottom. Pass the short end of the tool for removing ear wax from the microphone hole on the battery compartment from the inside outwards. You should clean the microphone input on a daily basis, after using a hearing aid.
Important: Do not insert foreign objects into the microphone. On some entotic devices Mic is protected by the lid. In this case, for cleaning your microphone use some special brush.
Protect your hearing aids, and they will serve you for a long time!

Modern technologies provide us with lots of advantages.

Hearing problems of various natures are fairly common diseases, unfortunately. But modern medicine can help to many hard of hearing people by offering them the latest models of hearing aids. These devices can improve the hearing impaired as a result of congenital defects or because of various acquired diseases. Nowadays there are a lot of different types of hearing aids on the market, and each device has its own peculiarities. Selection of model of hearing aid must take place with the mandatory consultation of ENT doctor or a specialist audiologist who will perform the necessary tests on the state of the patient’s hearing.

Despite the fact that manufacturers of modern hearing aids are trying to produce the most comfortable and invisible device models, getting used to it may take some time. First of all, wearing a hearing aid should not lead to complexes and embarrassment. There is no reason to shy of device that can establish normal communication with other people. Like and any device designed for continuous wearing, the unit takes some time for getting used to, which is individually in each case. Experts believe that the average period of adaptation to the apparatus is up to 10 days, but if after two weeks or more the patient continues to feel discomfort using the device, probably he must to chose other hearing aid. In the period of adaptation it is important always to use the device: it will not only speed up the habit, but will quickly re-establish communication skills, and auditory function.

Any hearing aid is a device designed to restore lost function of hearing. For its fully performing functions, the patient should want to use it consistently. A period of adaptation to the device will be longer or shorter, depending on what parts of the auditory analyzer patient affected by. It’s harder to correct disturbance in the central. It can be corrected by different auxiliary devices. In addition, habituation occurs more rapidly in young and active patients, as well as those who started to use the device almost immediately after the detection of hearing impairment.

After device selection the doctor sets it, focusing on patient’s perception of individual sounds. Most modern devices allow you to fine-tuning of the frequency-amplitude characteristics of a hearing aid. In some cases, some remedial sessions may require, during which the specialist will make necessary adjustments in accordance with the subjective feelings of a patient with an interval of 10-15 days after the use of the device.

Using a hearing aid, the patient must pay attention to a number of characteristics of auditory perception. First, the intelligibility of speech in different conditions – indoor, outdoor, in the silence, the perception of his own voice, surrounding sounds. The device should not cause extraneous sounds while wearing – whistle or noise. Often the first few days using a hearing aid become a real test for the patient who can not cope with the flow of auditory information, quickly gets tired and feels the need to remove the device.

You should not do it, because only constant wearing of the device will help you to get used to it and to restore lost auditory function.

Current technologies provide us with many advantages. Among them there are not only things for our comfort but also different appliances such as hearing aids which assist people to overcome phisical limitations. Those who suffer from deafness and require such kind of devices, are welcomed to visit this hearing aid prices site – this is the right spot offering much details about hearing aids and how to buy them.

Hearing aids are an accessory that helps people with hearing impairments to lead a full life. Such an apparatus is worn either behind the ear or in ear canal. Modern hearing aids are so microscopic that almost imperceptible. They consist of a speaker, microphone, microchip-amplifier, power is carried by a small battery. One of the most important properties of hearing aids – the highest quality of playback of different sounds. If the hearing aid has bad sound, it is the first sign that the machine defective. In quality performed hearing aid chip reduces background noise clearly distinguish speech, regulate the amplification of sound in the unit.
All modern hearing aids are classified (by way of sound processing) on:

1. Digital – based on the processor that provides all the algorithms of incoming sound. Such hearing aids are controlled automatically, and tinctures are modified depending on the desired program. The newest digital hearing aids separate speech from all background noises, that results in easier understanding and perception of speech, it sounds soft, you can hear many different sounds. Contact acoustic communication occurs in some models. There are more function in digital hearing aids, and they can compensate almost all hearing problems.

2. Programming – the basis of such hearing aids is that they configure on PC with specialized programs in accordance with the hearing person and non-numerical method of amplification. There is no mechanical control in such hearing aids, that result in a stability of their work. A peculiarity of these devices – this is automatic equalization for strong or weak signals, the presence of multiple channels of sound settings, ease of use.

The design of hearing aids is divided into: in-the, BTE, intracanal. There are pocket-type hearing aids, but usually they are produced customized. Physician surdologist will recommend you what type of hearing aid is for you.
How to choose a hearing aid?

First, the doctor should consult you and using a survey will determine how much your hearing is lost and what kind of device will fit you. Basic properties of hearing aids: audio processing, the number of frequency channels, the ability to clarify the thresholds of hearing, flexibility of configuration, the ability to understand a whisper, quiet speech, the perception of your own voice, comfort during phone calls, suppression of the internal noise of hearing aid, the ability to perceive loud speech, the intelligibility of speech in noise.

The company, selling hearing aids, must be licensed to trade in medical equipment market. All hearing aids are tested and adjusted, they are warranted, and issued with instructions in Russian. Materials for the ear cushions must be certified. Usually, companies that sell specialized equipment such as hearing aids exercise their warranty and post-warranty repairs, consult users. Price of hearing system is directly depend on novelty of this or that technological model of a hearing aid, difficulty to find a hearing aid, etc.

However, already approved models of hearing aids produced by traditional techniques are affordable. If hearing is lost in both ears, the best way can be binaural prosthesis with two hearing aids, in result the sound will be close to natural. Hearing aids that were made qualitatively work up to six years, but they require proper care. Hearing aids should be cleaned, carried out with preventive maintenance. In addition, any hearing aid should be used to.

Modern technologies provide us with lots of advantages. Among them there are not only things for our convenience but also various appliances such as hearing aids which help people to get over phisical limitations. Those who suffer from deafness and are in need of such kind of devices, are welcomed to go to this affordable hearing aids site – this is the right place offering much details about hearing aids and how to purchase them.

But the technologies do not only provide us with appliances and tools, they also are the means for looking for those devices. Say, if you need oticon hearing aids, it is smart to use the Web network.

Hearing aids assistance is a very complicated process and needs not only efforts both psychological and financial but also patience. You should be persistent in your steps forward your hearing loss recovery and always be sure in success. Motivation is a very important thing and you should be motivated and see your aim and your aim is your good hearing and doesn’t matter how you will get, thanks to your personal hearing or to hearing aids assistance.

If necessary – if there are suspicions about presence of infringements in the field of a middle ear – impedansometry is conducted, this allows to estimate mobility of an eardrum and to exclude liquid presence in the average ear.

Possessing all completeness of the information, a hearing aids expert starts hearing aid selection. First of all, being based on the data of audiograms (voice-frequency and speech), he offers the patient a choice of some models of the hearing aids, capable to compensate the given loss of hearing. The patient after pretuning chooses the most suitable variant, being guided thus by the following criteria: how good legibility of speech is provided by the given hearing aid, whether naturally it sounds, whether own voice is deformed, how attractive it is outwardly (the size and device type – entotic, parotid) and, certainly, how much it costs.

Besides, special programs of selection and the options of hearing aids helping to hearing aids expert are widely applied, on the basis of the data audiogram of the patient, correctly chosen and optimum to adjust a hearing aid. One of such programs is CONNEXX, developed by Siemens.

Anamnesis gathering, diagnostics and selection of the hearing aid demands considerable expenses of time and efforts, both from the side of the expert, and from the patient. The first reception at a hearing aids expert, including device selection, can last till two hours.

When the patient has chosen the model of the hearing aid most suitable to him, the expert conducts a preliminary adjustment of the device directly on an ear of the patient.

Besides, the expert can offer to the patient various accessories and additional accessories to hearing aids: • children’s accessories – a special children’s small horn, and also multi-colored cases for some models of hearing aids; • other accessories – for example, audioboots, and also conditioning agents behind hearing aids and intraear liners (special cleansing sprays, napkins, bags for a pulling of a moisture from hearing aids).

The detailed maintenance instruction necessarily should be applied to the device. The hearing aid and the materials used for manufacturing of intraear loose leaves should be certificated. It is desirable, that guarantee and after guarantee repair was made in the same centre where the patient gets a hearing aid. In an ideal it there should be an authorized official distributor of the known manufacturer of hearing aids.

Current technologies bring many benefits. Among them there are not only things for our convenience but also various devices such as digital hearing aids which help people to get over phisical limitations. Those who suffer from deafness and require such kind of devices, are invited to visit this hearing aid prices site – it is the right spot offering much details about hearing aids and how to purchase them.

In this article it will be a question of a hearing aids assistance process.
So, the doctor- otorhinolaryngologist or surdologist has diagnosed relative deafness and has directed the patient to the hearing aids expert. Only small percent of a proof hearing disorder can be improved by means of operation and medical products. In overwhelming majority of cases (about 90 % from total suffering from relative deafness, and according to the data of WHO – the World Organization of Public health services) hearing drop can be compensated by hearing aids assistance. As hearing drop inevitably limits possibility of the person to communicate, gradually leads to his social isolation, losses in interpersonal and professional relations, it is possible to define hearing aids assistance as restoration of communicative ability of the person, suffering from a hearing disorder, by means of the hearing aids which are correctly selected and have been adjusted by the expert according to individual features of hearing loss.

Hearing aids assistance is carried out in specialized establishments – the hearing aids centers and includes:
• gathering of the anamnesis (disease record)
• check up (otoscopia, audiometry, if necessary additional methods)
• hearing aid selection
• hearing aid adjustment (primary and the subsequent thin)
• otoplastics (manufacturing of the individual intraear loose leaf)
• adaptation to the hearing aid
• a quality estimation of hearing aids
• accustoming (habilitation) and rehabilitation (trainings with surdologists for children)

The expert who is engaged in hearing aids assistance, is called hearing aids expert. As hearing aids assistance as a specialty, is on a joint of many disciplines – medicine, acoustics, chemistry, microelectronics, psychology, an expert in this sphere should possess knowledge from all these areas.
The first reception in the center begins with conversation of a hearing aids specialist with the patient, the purpose of such a conversation is disease record, or anamnesis gathering – that is data on the transferred diseases, a heredity, and also the information on a way of life of the patient (professional work, habits, hobbies). Gathering of fuller information on the case record of the patient is the major condition of his further successful prosthetics and rehabilitation.
Further the expert spends otoscopia that is a visual inspection of external acoustical pass by means of an otoscope about presence of foreign things in it, and also for finding-out of features of its structure, a condition of an eardrum, possible presence of postoperative cavities, inflammations.

In an ideal before prosthetics speech audiometry should be also spent: definition of the percentage of words which the patient can distinguish at various loudness of their reproduction. Speech audiometry, spent before prosthetics is important for the subsequent estimation of quality of prosthetics. Comparison of results of speech audiometry before prosthetics allows to estimate its quality objectively (in %). Actually, it is a unique objective method of hearing aids efficiency. In some countries, for example, in Germany, speech audiometry is an obligatory method of check up.

Modern technologies bring many advantages. Among them there are not only things for our comfort but also various appliances such as hearing aids which assist people to overcome phisical limitations. Those who suffer from deafness and require such kind of devices, are invited to go to this hearing aid prices site – this is the right place offering much info about hearing aids and how to order them.

How does the brain distinguish sounds? The acoustical nerve consists of thousand the thinnest nervous tissues. Each tissue begins from a certain site of a snail and transfers certain sound frequency. Low-frequency sounds – for example, car or train noise, are transferred on the tissues which are starting with a top of a snail, and high-frequency – for example, a twitter of birds, – on the tissues connected with its basis. Thus, various sounds cause electric excitation of various tissues as a part of an acoustical nerve. The brain is capable to perceive and interpret these distinctions.

But to distinguish sounds – there is not the final aim. It is necessary to understand their sense. The structure of an internal ear in itself promotes allocation of significant sounds from useless noise. The brain uses the memory and experience for “judgment” of the sound heard directly in the course of perception. So the child of an infant age, using small experience, is able to distinguish voices of mother and father and to distinguish them from each other, yet without understanding the pronounced words.
Methods of diagnostics of a hearing disorder:

• Audiometry is the simplest and accessible research with the help of which the size of hearing loss is estimated. It is used voice-frequency and speech audiometry. At voice-frequency audiometry each frequency is investigated separately by means of sounds of various loudness. Usually the person is capable to perceive sounds frequency from 20 to 20000 Hz. For understanding of speech it is enough to hear sounds in a range from 200 to 6000 Hz. Speech audiometry allows to define percent of words which the person can distinguish, at various loudness of their reproduction.

• Impedansometry (timpanometry) allows to define infringements on the average ear. This method estimates mobility of an eardrum and excludes a liquid presence on the average ear.
• Otoacoustical emission allows to estimate a condition of hair cells, that is diagnoses the function of a snail of an internal ear.

• Registration of the caused electric potentials of a brain allows to define presence of defeats of an acoustical nerve or a brain. The method consists in measurement of electric activity of a brain in reply to sound signals.
The last three methods are objective and can be used for preliminary treatment of a hearing disorder even at newborn children.

Types of loss of hearing. Hearing drop in medical language is called as relative deafness. The relative deafness caused by obstacles in a way of amplification of sounds, is called conductive. It occurs:

• at a level of an external ear (a sulfuric plug, developmental anomalies of an external ear);

• at middle ear level (bores and eardrum damages; damage of acoustical stones; otosclerosis, breaking mobility of acoustical stones).
Such relative deafness is usually corrected by a surgical way. In rare instances additional appointment of very simple hearing aid is necessary – it should simply amplify sounds.

Modern technologies bring many advantages. Among them there are not only things for our convenience but also different appliances such as hearing aids which help people to overcome phisical limitations. Those who suffer from deafness and need such kind of devices, are welcomed to go to this affordable hearing aids site – this is the right spot offering much details about hearing aids and how to buy them.

According to the statistics, now every sixth person in the world has problems with hearing. The modern level of development of medicine and techniques allows to assist successfully to overwhelming majority of people with the hearing loss. Hearing aids are necessary for people even with a big loss of hearing: for orientation in space (it is important for everyone to hear coming nearer transport to react to a call), for dialogue with hearing (for example, in public places and establishments) and hard of hearing (not everybody knows sign speech), for an employment.

Hearing aids assistance is a unique way of high-grade social rehabilitation and integration. Especially important timely, that is earlier, adequate hearing assistance of deaf and hard of hearing children. Only having provided a child with correctly adjusted qualitative hearing aids, having given the chance to hear himself and associates, it is possible to teach him speech, to provide his occurrence in the world of sounds, the world of human dialogue, to give it high-grade education, that is to provide his future.

The patient should understand accurately: time is required for getting used to the hearing aid. Devices cannot give immediate improvement. It not points which simply enough to put on, and the person starts to see at once well. Hearing aids are more similar to skis. To buy a good pair of skis is only the beginning. Everyone knows, how long and how persistently it is necessary to train to learn to ski. The same thing is with hearing aids. The best hearing aid cannot be bought, it is necessary to work daily over it. Only in the presence of sufficient practice surrounding sounds will start to sound naturally, and the brain will get used to background noise and will cease to notice them.

Though to start to use hearing aids it is recommended in slow rate, the patient should realize the purpose facing it accurately: to learn to use a hearing aid daily and within the whole day. By the end of the second week the person should put on the device right after awakenings and remove it when going to bed. While the hearing aid does not become a part of a habitual way of life of the owner thanks to constant use, the patient’s brain will not receive sufficient stimulation to learn to interpret real sounds of world around. Hearing aid use only during this period when the person carries out the social functions is a big error. In this case sounding of the device remains unusual therefore the patient can at all refuse to use it.

Firms-manufacturers already apply this knowledge for a creation of programs of adjustment of the acoustical systems. At primary prosthetics the principle of step approach to optimum strengthening, depending on degree of hearing loss and adaptation of the patient is used. Purposeful use of knowledge of adaptation allows the computer program to calculate the strengthening of the most suitable at present that raises spontaneous acceptance of hearing aids.

Current technologies bring many benefits. Among them there are not only things for our comfort but also different devices such as hearing aids which assist people to overcome phisical limitations.

Very seldom hard of hearing person who for the first time has received hearing aid, can take at once all advantages of the strengthened hearing. Process of hearing aids assistance develops in several stages: initial adjustment, adaptation and specifying adjustment. And, most of all it is required to time for adaptation which includes variety of factors. And simple accustoming to the foreign matter which has lodged in acoustical pass is only an iceberg top.

Much more problems are connected with so-called «confusion of hearing». It is caused by a stream of sounds of environment which have suddenly rushed in consciousness of the person after he did not hear them for a number of years. In this initial stage all patients show similar complaints: an unnatural timbre of sounding (with “a metal” shade), unusual sounding of human voices (especially own) and presence of background noise. The true reason of this phenomenon has been found out more recently. It appears, that in process of development in the person high-frequency of sensoneural hearing losses (which according to the statistics makes up to 90 % of all cases of relative deafness) the acoustical centers in a cerebral cortex, responsible for processing of quiet high-frequency sounds, cease to be exposed to sound stimulation.

But the central nervous system of the person possesses such remarkable property, as plasticity, that is, ability to change eventually in reply to change of the arriving touch information. Thanks to plasticity of a brain the person recovers after a stroke when the intact sites of a brain incur functions of the damaged. Speaking differently, the human brain is not only improbably powerful alarm processor, but also eventually itself will reprogram optimum to process the received information. Considering that sensoneural relative deafness progresses slowly and that in most cases the person does not hasten to come to the surdologists, even having found out signs of loss of hearing, this process usually proceeds for a number of years.

Taking into account this circumstance «the confusion of hearing» at primary prosthetics becomes quite explainable. When hard of hearing person thanks to a hearing aid receives necessary strengthening earlier not audible surrounding sounds become heard and get to a brain. However those acoustical centers which were used earlier for decoding of sound signals of high frequency and low intensity, during relative deafness have been translated on processing of other sound stimulus. That is, a brain starts to perceive sound signals practically at once, but in the beginning it is not in forces to process them. Some period of time therefore is required for the return reorganization to be carried out.

Experimental data testifies that from several weeks to several months are required for the adaptation process. All depends on how long there was no sound stimulation and in what scales. During carrying out speech audiometry it was revealed that within the first 3-6 weeks the understanding of speech remains at former level, and then starts to improve, and sometimes within the whole year. Adaptation process can be accelerated thanks to intensive training. Besides, the more hi-tech the hearing aid is, the more precisely it is adjusted on conformity of hearing loss and the more adequately it corrects, the shorter is accustoming time. At last, adaptation in a huge degree depends on motivation of the person.

Current technologies provide us with lots of benefits. Among them there are not only things for our convenience but also various appliances such as hearing aids which help people to get over phisical limitations. Those who suffer from deafness and are in need of such kind of devices, are welcomed to go to this hearing aid prices site – this is the right place offering much details about hearing aids and how to buy them.

What can have more negative affect on the small child than the constant loneliness? For the child it is a real torture when he loses hearing. For an all-around development of the child it is necessary for him to hear and perceive sounds, speech. Children who have lost hearing in full or in part, have no necessary dialogue, training and, as a result, development. It is inconvenient for them to communicate well with surrounding peers.

Children start to feel complexes and to feel defective very sharply. However loss of acoustical abilities is not a desperate situations and it is not necessary to be reconciled with the given disease! People having problems with hearing have a magnificent possibility to cope with the given illness and to return to the commonplaces and to return on the workplace. Though there is no possibility to correct completely hearing, but it is possibility to compensate by means of modern technical devices and to return possibility to hear and distinguish sounds.

Thanks to the development of scientific and technical progress in use the tiny devices today are invented and introduced, capable to return hope to hard of hearing people to hear and to lead a healthy way of life in a circle of the colleagues and close people. Presently various types of these small products are made many. They differ in the sizes, in a set of functions, various color execution and a device principle.

This is an erroneous opinion that the acoustical device is a bulky thing which is noticeable on an ear. It is not so at all! The latest kinds of hearing aids are so tiny and various that you hardly probable can learn that your interlocutor has problems with hearing. The hearing aid of new generation can be accepted easily for an ornament, so this device is indistinguishable from usual ornaments. Acoustical devices can be of different types: some are worn directly in the ear channel, others fasten on the outer side of an ear. Despite presence of different types of acoustical adaptations all of them are similar by the design of the device.

Into the scheme of the ear device there included: a microphone, a dynamic and the amplifier-microchip. For today of technology in the field of acoustical adaptations have reached considerable heights that modern devices differ by a tremendous quality of a sound reproduction, in the insignificant sizes and are issued for all groups of patients. So, for example, for persons of advanced age for whom a small motility of fingers is peculiar, in view of age, special models which allow to operate loudness level freely are issued.

Therefore, we parents, are able to free our children from complexes and let them lead a normal life, wwithout any difference from his schoolmates or friends.

Modern technologies provide us with many advantages. Among them there are not only things for our comfort but also various appliances such as digital hearing aids which assist people to get over phisical limitations. Those who suffer from deafness and need such kind of devices, are welcomed to go to this hearing aid prices site – this is the right spot offering much details about hearing aids and how to order them.

Hearing drop in medical language is called relative deafness. The relative deafness caused by obstacles in a way of amplifying sounds, is called conductive. It arises:
- At level of an external ear (a sulfuric plug, developmental anomalies of an external ear);
- At middle ear level (bores and eardrum damages; damage of acoustical stones; otosclerosis, breaking mobility of acoustical stones).
Such relative deafness is usually corrected by a surgical way. In rare instances additional appointment of a very simple hearing aid is necessary – it should simply amplify sounds.
The relative deafness connected with infringement of transformation of mechanical fluctuations in electric impulses, is called sensoneural. For the given type of relative deafness it is characteristic not only drop of sound perception, but also its distortions. Thus
- The painful threshold decreases; sounds intensity hardly become louder than an audibility threshold intolerable whereas for normally hearing people the painful threshold makes nearby 100 db;
- The perception of speech against noise is a loss. The reasons of sensoneural relative deafness are:
- neuritis (surrounding deprive, an epidemic parotitis etc.);
- A pressure of liquids of an internal ear (illness of Menera);
- Age drop of hearing;
- A pathology of an acoustical nerve.
Sensoneural relative deafness cannot be cured a surgical way. Electronic schemes of appointed hearing aids should be more difficult to correct specific features of hearing of the concrete patient, characteristic for the given kind of relative deafness.

The mixed relative deafness represents a combination of two aforementioned types of a hearing disorder that is a combination of conductive relative deafness with defeat of an internal ear. Principal causes of this kind of a hearing disorder:
- Infection of snails at a chronic inflammation of an ear;
- Stratification of age factors on not operated otosclerosis.
Such patient should be appointed the same hearing aids, as at sensoneural relative deafness.

Seldom full deafness is met as a result of bilateral destruction of cells of a snail perceiving a sound, and sometimes and an acoustical nerve. In such cases electric stimulation of an acoustical nerve or the acoustical centers of a brain is necessary for hearing restoration. Very difficult devices are cochlear or stem cells implants are thus used. By operation in skull bones insert the thinnest wire – an electrode, and submit electric impulses at once on an acoustical nerve. The given method of correction demands long and difficult rehabilitation.

Hearing drop in overwhelming majority is up to 90 % of cases can be compensated by means of a hearing aid. Hearing aid is the only help for people who suffer from an unpleasant deasese – hearing loss. Thanks to the human progress and inventions hearing aids appeared with the aim to ease the human life and to liberate him from complexes and hindrances for comfortable living.
