Why can't I hear clearly with a hearing aid?

Hearing impaired patients can basically adapt to hearing AIDS after the initial adaptation period and several debugging. At this time, you may feel that the hearing aid is very good, the hearing is clear and comfortable. But one day, I suddenly found that hearing AIDS were of little use. Usually there are two possibilities in this situation. The first is that there is something wrong with the hearing aid, and the second is that your hearing has changed.

Today we will talk about the first possibility, that is, the possibility of hearing aid problems.

If you suddenly feel that the sound of the hearing aid is getting smaller or there is no sound, we should consider three possibilities:

1. Hearing aid battery problem

2. The hearing aid is damp.

3. The sound hole or microphone is blocked.

First of all, we suggest you check the battery to see if it is fully charged. You can try changing a battery. If it is a battery problem, it can be solved by replacing it with a new battery. However, some of the patients we contact will do this. After replacing a battery, they found that the hearing aid was still not back to normal. At this time, they changed a new battery and continued to try, so they changed four or five batteries in a row. This is incorrect, and it is a waste of batteries. As long as the protective patch is removed, the zinc-air battery will continue to discharge even if it is not used, and it will be dead once it is discharged.

I can teach you a little trick here. If you choose two hearing AIDS of the same model, you can remove the battery of the hearing aid that works normally and replace it with the hearing aid that has problems. At this point, if the hearing aid returns to normal, it means that it is a battery problem, and we can replace it with a new one. If the hearing aid still does not return to normal at this time, it means that it is not our battery problem. This is both economical and simple. In addition, there is now a hearing aid electroscope, which can quickly detect the battery charge. This little thing is still very convenient and can be bought in the fitting center.

If the hearing aid does not return to normal, it is likely that the hearing aid is wet, especially for patients living in a humid environment in summer. When the components inside the hearing aid get wet, some problems will occur in the hearing aid, such as the sound becomes smaller or there is no sound. If the hearing aid is wet, we need to dry it in a special electronic drying oven for 3-6 hours, and then check whether the hearing aid can return to normal. Never bake with fire or blow with a hair dryer. Use a special electronic drying oven. These are available in the fitting center. If you can't do it yourself, you can take them to the fitting center for drying and maintenance.
