Before the user takes the machine home and adapts to wear, the fitting examiner will tell him to wear it in a quiet environment for a period of time. Many users don’t think so. Sometimes when they feel that they can’t hear clearly, they directly turn up the volume, but rarely turn it back. Once you get to a noisy place, you will feel a special noise.

In general, the first time you wear the machine, the sound will be a little bit smaller, but not so that the user can’t listen at all. Because the first fitting place is in the fitting center, the environment is somewhat different from the actual living environment, which is relatively quiet. In addition to this reason, the sound quality is the most important thing for the match maker. If the sound is too loud blindly, it will appear very noisy, with a lot of noise, and it will be hard to hear. Can’t you turn up the volume?
The ability of human ear to deal with sound is better than that of hearing aid, but if human ear loses its ability to deal with sound, it needs the help of hearing aid, but it doesn’t mean that hearing aid can completely replace human ear. The higher the volume of the hearing aid is, the more frequency it will receive, but if it is not processed, it will become noise.
We often say that the digital programming machine is to use the computer program to control and process the sound of various frequency bands. But the hearing aid processing capacity of each model is different, which is the fundamental difference between high-end and low-end machines.
Many old friends, due to the deterioration of their body functions and the decline of their speech discrimination ability year by year, so the sound quality is particularly important. The voice is smaller, the information processed is less, and the old people can hear more clearly. After a period of adaptation, you can adjust it again and try to listen to more sounds.
