Because the auditory nerve is not stimulated after hearing loss, the longer the time will lead to the slow response of the brain and the decline of speech resolution, the earlier the intervention, the sooner the treatment effect will be better.The wearing effect of hearing aids is related to hearing and their own speech discrimination ability. To be precise, as long as the hearing is impaired, wear hearing aids as soon as possible to avoid the deterioration of speech resolution resulting in poor hearing aids.
If the hearing loss is too long, even young people will not wear it as well as those who have a short hearing loss. This is because the brain has not heard sounds for a long time, and the brain function is degraded, which causes the brain’s perception ability to deteriorate, which is often Said the resolution is poor, if the hearing loss has been diagnosed, wear it Hearing aid , Even if you get older, the wearing effect can be maintained.However, it cannot be ruled out that some of the elderly’s own diseases, such as high blood pressure, diabetes, and cardiovascular and cerebrovascular diseases, will cause hearing loss again. Hearing aid , Suddenly one day the effect is very poor.Therefore, if hearing problems are found, they must be treated and intervened early. The elderly must pay attention to preventing senile diseases.
The so-called speech resolution refers to the patient’s recognition percentage of words (usually tested with Yangyang words) when the sound is amplified to the most comfortable size for the patient (you can hear the words and understand and repeat them).Before wearing the hearing aid, the optician will do a series of hearing tests for the patient, including pure tone hearing threshold, comfort threshold, discomfort threshold, speech recognition rate, etc. These factors will affect the wearing effect of hearing aids. The worse the pure tone hearing threshold, the worse the effect. The lower the comfort threshold, the harder it is to debug the hearing aid. Of course, the speech recognition rate we are going to talk about today also largely determines the effect of the patient wearing the hearing aid.With the same degree of hearing loss and the same dynamic range of speech, the higher the speech recognition rate, the better the effect of wearing hearing aids.
The function of hearing aids is only to amplify the sound to the range that the patient can hear, but hearing aids cannot improve the patient’s own speech resolution, so why do others bring hearing aids with good results, and you are not good?This is really incomparable. It is definitely not just a hearing aid problem, nor is it just a problem with the level of the optician. You need to look at your own resolution level first.
