1. Hearing aids are actually a super-small loudspeaker, and have no therapeutic effect on the disease that caused the hearing loss. In the selection of hearing aids must go through the otolaryngologist formal examination and treatment, after treatment of irreversible hearing loss of most of the people can be equipped with hearing aids, regardless of the type of hearing loss is sensorineural deafness, mixed deafness, or conductive deafness. But some diseases, such as auditory neuropathy, progressive hearing loss of the auditory neuroma, some of the brain center disease caused by auditory abnormalities, etc., the use of hearing aids will be very poor or ineffective.
2, according to the WHO standard hearing loss degree is divided into: mild 26-40 dB; moderate: 41-60 dB; severe: 61-80 dB; extremely severe: more than 80 dB. Simply put, once the hearing loss affects the ability of speech communication (such as answering the phone, face-to-face communication in noisy environments and other difficulties), hearing aids should be fitted as soon as possible. For special people, such as occupational requirements, often participate in important negotiations, major social activities, etc., mild hearing loss can be optional hearing aids. At the same time, it should be understood that, for severe sensorineural deafness, hearing aids can not be fully compensated for, must rely on lip reading, expression, association and other ways to help, and for very severe sensorineural deafness hearing aids can only provide partial help, this time, cochlear implantation is more effective, such as cochlear implants can also be equipped with hearing aids, but at this time, the main purpose is to maintain an acoustic environment, avoid or delay the hearing and speech in the hearing. However, the purpose of hearing aids is to maintain a sound environment and to avoid or delay the deterioration of the auditory and speech centers. The first thing you need to do is to get a hearing aid, and then you'll be able to get a hearing aid to help you.
3, according to the International Organization for Standardization (ISO) survey, in the noise level of 85 decibels and 90 decibels in the environment for 30 years, the possibility of deafness were 8% and 18%. Therefore, hearing aids that indiscriminately amplify noise and speech can be detrimental to hearing under certain circumstances. Therefore, a good hearing aid should be able to: automatically adapt to the environment, effectively reduce noise, targeted to improve the recognition of speech frequencies, to protect the residual hearing; natural reproduction of sound, optimize the patient's perception of their own voice, to improve the naturalness of the sound, authenticity and comfort; automatic elimination of the feedback sound (whistling); hearing aid parameters can be adjusted according to the wearer's hearing changes; the function of hearing aids with the upgrade of the optional software. The parameters of the hearing aid can be adjusted as the wearer's hearing changes; the functions of the hearing aid can be enhanced with the upgrading of the hearing aid fitting software.
4, hearing aids are not a simple commodity, can not be purchased and used at will, must be strictly fitted to wear. The fitting staff should be professionally trained, and the fitting process also requires hearing tests, hearing aid audition, and effect evaluation, etc. If the fitting is not done properly, the result will be a loss of the hearing aid. If the fitting is not done properly, the consequences can be very serious. Hearing aids are not a "one-shot deal", after the initial selection is completed, the dispenser will make regular visits (7 days, 30 days, 180 days, etc.), and there is wear unsatisfactory place can be booked at any time to debug again.
Hearing aid debugging program includes: hearing aid gain adjustment, output adjustment and adjustment of various functions. For the first time for patients with hearing aids, hearing experts or fitters will be more conservative in the initial adjustment of the loudness and the selection of various functions, the patient wearing the first 1-2 months is the adaptation period, with the patient's own adaptation to the progress of the different need for different adjustments, generally 1-2 times fine-tuning, for the hearing of patients with complexity of the patient will need to be more debugging until the adjustment of the appropriate so far.
5, wear hearing aids for a period of time if you feel the effect of decline or even ineffective, to distinguish between different situations to deal with. If you are wearing a hearing aid at the beginning, you need to contact and communicate with your hearing specialist or fitter to determine whether it is a normal adaptation process or a failure to grasp the wearer. Because the hearing aid wear early hearing experts or fitter of the hearing aid gain adjustment will be more conservative, the patient to adapt to a period of time is required to adjust a variety of debugging program. However, if accompanied by other conditions, such as a sudden decline and exclude hearing aid problems, or tinnitus, vertigo, headache, etc., should seek the help of otolaryngologists in a timely manner, except for the aggravation of pre-existing diseases or new diseases.
6, hearing aids are recommended to be used for life, but the daily wearing time varies from person to person. For people with mild hearing loss, they can choose to wear them when they need them, and for those with moderate loss or more, they should wear them frequently in their daily life. For pre-language deaf children, in addition to sleep, bathing, rainy days, outdoor work and other circumstances is to wear, in order to ensure that the hearing compensation and speech learning.
Hello! If the sound of the hearing aid is light or there is no sound in the process of use, please check yourself according to the following steps: 1, is the battery charged? Replace the battery with a new one; 2. The sound hole of the ear mold and the cerumen baffle may be blocked, use a special small brush to clean it; 3. Is the program button in mute? Move the program button several times; 4. Is the volume switch turned off? Move the volume switch left and right. 5, ear back machine no sound, need to look at the white tube whether there are water beads if so, take down and clean it. If the above steps still can not be resolved, please go to the center store to deal with

But from the technology of hearing aids, can be divided into digital and analog machines. In terms of brand, there are Rishengda, Phonak, Stantec and other brands. In terms of price, there are a few hundred, more than 1,000, more than 2,000, and even tens of thousands.
As a person who has not been in contact with this industry, there is only the difference between the appearance and the brand, and many people think that the brand is the same, the appearance is almost the same, why there will be so much difference in price, then this is the chip technology of the hearing aid! Analog machines do not have a chip, just an amplifier, while digital machines use a good or bad chip will determine the price of hearing aids. The more adjustable channels, the better the chip, the more features, the better the noise reduction technology, the higher the price!
1. Daily cleaning is indispensable. After use, use a dry, soft cloth to clean the earwax and sweat off the surface of the hearing aid. Use a small brush to brush away the earwax and other tiny particles that accumulate around the sound hole of the hearing aid, the volume adjustment knob and the battery compartment.2.
