Why do hearing aids have channels?
Hearing aids use channels for better sound processing. One of the
main benefits of breaking up the frequency range into channels is
that it enables hearing aids to differentiate between speech and
noise. Different amounts of gain (amplification) can be applied to
each channel. This is important because you do not necessarily want
the same amount of amplification at all frequencies. Usually, noise
is more of a low-frequency type sound, while speech is more of a
high-frequency sound. If a hearing aid only had one channel for
instance, the same amount of amplification would be applied to all
frequencies in that one channel.
However, the benefits of multiple channels extend beyond the amount of amplification. Hearing aids can also apply different features to varying degrees in different channels. In fact, the operation of most signal processing features (e.g. expansion, compression, noise reduction, feedback cancellation, and multi-channel directionality) is channel-specific. So, if a hearing aid only had one channel, the same features would also be applied to all frequencies in that one channel. Hearing aid channels contribute towards more specific processing and amplification of sounds received by a hearing aid.
