There are two types of hearing aids on the market today, one is analog hearing aids, the other is digital hearing aids, and older box hearing aids have basically been eliminated, so we will not discuss them.
In fact, the current hearing aids are basically digital hearing aids, and the rest are less than10%Simulated hearing aids will also be in the future10The whole reason for the elimination in the year and the elimination of the hearing aid is because the hearing aids are not effective. So let me take you here to find out why the analog hearing aids are not as good as the digital hearing aids.
The reason why the analog hearing aids are not easy to use is because such hearing aids can only linearly amplify the sound. The simple point is to amplify all the sounds of the outside world including those noises, so this leads to a phenomenon, which is whispered. Clear, loud and arguing, this is also the reason why some hearing loss patients are still noisy after wearing a hearing aid.
The analog hearing aids have been worn for a long time. In terms of audiology, it will further damage our hearing, resulting in a lower hearing loss. At the same time, because these hearing aids can only amplify the sound, there is no recognition for speech. Help, so you can’t hear it clearly, you can’t hear it, you won’t understand it because the sound is changing. It’s going to be popular here. Not all of them can’t be heard because the sound is too light. In many cases, it’s hard to hear.
The front also said that the analog hearing aid is linearly amplified. The digital hearing aid is a non-linear amplification. From the above, the digital hearing aid is equipped with many functions that the analog hearing aid does not have. The core of the digital hearing aid is a chip, and its processing speed is extremely high. It’s fast, and it changes automatically with the surrounding environment. If you are in a noisy environment, the digital hearing aid will activate the noise reduction function to increase the speech by amplifying the volume of other people’s speech. resolution.
Because of the noise reduction function, the analog hearing aid can never be compared with the digital hearing aid in terms of comfort alone. Secondly, the digital hearing aid can also relieve the hearing loss. Although the normal hearing loss can not be prevented, However, it can prevent hearing loss caused by noise, and it can also protect the residual hearing.
