What's the difference between a digital hearing aid and a simulator?

First of all, there is a difference in price: digital hearing AIDS are relatively expensive, and analog hearing AIDS are cheaper.

Secondly, the simulator uses linear amplification technology to amplify all sounds, which is quiet and loud, just like putting a loudspeaker on the ear, which often makes the wearer feel too noisy. Long-term use may also cause secondary hearing damage, and the more you wear it, the more deaf you become.

Professional hearing AIDS are mostly digital machines, which use nonlinear amplification technology to reduce noise in sound compression. The hearing of human ear is divided into high frequency, medium frequency and low frequency. Some people have serious high-frequency hearing loss, while others have serious low-frequency hearing loss. According to different hearing loss, we should not blindly amplify all the sounds, but should carry out targeted debugging according to different frequency bands of hearing loss. The sound channels in digital hearing AIDS can compensate the hearing loss in different frequency bands, realize natural and clear sound, and make users comfortable to wear.

It should be noted that hearing AIDS are not "commodities" that can be purchased at will.

Due to the weak public awareness of hearing AIDS, coupled with the proliferation of cheap analog hearing AIDS that do not require fitting, most people think that hearing AIDS can be worn at will when they come back. In fact, hearing AIDS are not "commodities" that can be purchased at will, but second-class medical devices that need to be matched according to my hearing situation.
