I believe that when you get started with hearing aids, you will notice a parameter – channel, 48, 32, 24… What do the different channel numbers mean?
First of all, the number of channels is indeed one of the important indicators to measure the performance of hearing aids。
As shown in the figure below, each dot has a color, representing a channel, and the denser the dots, the more natural the color transition. So the more channels there are, the finer the adjustable sound, and the clearer and more comfortable the sound you hear.

Benefits of multi-channel hearing aids.
With multi-channel technology, audiologists can independently adjust the amplification parameters of each channel, including gain, compression, and MPO for maximum loudest output, to meet the unique needs of each person with hearing loss. More channels means that debugging can be more refined, and sound compensation is more accurate, which means that the hearing aid sound can be adjusted more clearly and more comfortably. As the number of channels increases, the audiologist can minimize the loss of speech clarity while reducing noise. If the hearing aid has only one channel, then reducing the noise will also affect the amplification of speech sound, resulting in decreased speech clarity. In addition, multichannel technology includes directivity, speech enhancement and noise suppression, which allows the hearing aid to distinguish between noise and speech in the channel, and to separate the speech signal from the noise.
The number of channels is like the pixels of the camera, the pixels are very high, the photos taken are not necessarily good, but also consider the other functions of the camera. Therefore, in addition to the number of channels, when we buy hearing aids, we should also see whether it has noise management, wind suppression, Bluetooth direct connection and other functions. These functions work together to give you a great listening experience.
