As a cost-effective hearing compensation electronic device, hearing aids are gradually entering the life of hearing-impaired patients. While giving the hearing loss patients a convenient life, they have also been questioned. So, what factors affect the fitting effect of hearing aids?
First, the degree and nature of hearing loss:Generally, people with mild and moderate hearing loss can communicate in close distance. The hearing aid compensation effect is very effective. The moderate hearing loss can hear loud, but the hearing is poor in the noise environment, and the hearing aid is better. Severe hearing. The effect of wearing a hearing aid on a loss patient varies from person to person; those with very severe hearing loss are generally less effective in wearing a hearing aid. The hearing curve is flat, slowly rising or falling, and the wearing effect is good; while the high-frequency steep drop type, irregular type, and the rare low-frequency steep drop type effect are generally poor. The hair cells of patients with conductive sputum are not damaged, but the hearing dynamic range is up-shifted, and the compensation effect of hearing aids is very good. However, patients with sensorineural hearing loss, due to cochlear or posterior cochlear lesions, cause sensorineural disturbance, residual hearing loss, the effect may be Poor; the effect of mixed sputum is between the above two; central and non-organic hearing loss hearing aids are almost ineffective.
Second, speech resolving power:Hearing impaired patients tend to lose more time, the lower the speech recognition rate, the lower the listening effect. The lower the help from the hearing aid, the worse the listening experience will be. ≥90%, the effect is good; 70-90%, there is a substantial improvement; 50-70%, there is a slight improvement; ≤50% is not satisfactory.
Third, whether the binaural fitting:Most hearing-impaired patients have binaural hearing loss. Binaural hearing has many advantages over a single ear, such as binaural sound source localization, binaural loudness superimposition, binaural noise reduction, and binaural avoidance of hearing deprivation.
Fourth, the needs of different listening environments:Hearing impaired patients have different listening effects in different environments when using hearing aids. Listening in a quiet environment is often better than listening in a noisy environment, and the speech recognition rate is much higher. Listening to a single ear in a quiet environment is similar to that of a pair of ears, but listening in a noisy environment can be very poor.
5. Knowledge of hearing aids for hearing-impaired patients:Hearing impairment is a hidden obstacle. If it is not easy to be discovered by people, most people think that wearing a hearing aid is equivalent to making their obstacles open and affecting their own image. Others will look at themselves with different eyes. Therefore, some patients prefer to influence their social skills and are not willing to use hearing aids that are helpful to him. In the long run, they often influence the ability to understand language because of less and less interaction, causing serious communication obstacles and psychological problems.
6. Expectations of excessive hearing-impaired patients:Some hearing-impaired patients have unreasonable demands on the expectations of hearing aid wearing, or the actual situation of their own hearing. Essentially, a hearing aid is just an electronic device, and a high-end hearing aid is no substitute for its own ear function. Explicitly explaining the benefits and limitations of hearing aids to the hearing impaired can help guide the hearing impaired to establish reasonable expectations.
