Hearing Aid Bands and Channels 

Hearing Aid Channels - Hearing Aid Bands - What is the difference between bands and channels

The ability to understand speech is the prime function of a hearing aid. Human speech centers on frequencies between 250 Hz to 6000 Hz. By amplifying the speech frequencies and filtering out the non- speech frequencies which contain noise, speech is more understandable. Hearing Aids do this by working with bands and channels. First, let's look at bands. Bands are just like stereo equalizers. They are used to control volume at different frequencies. This allows us to adjust more volume in a specific area of your hearing loss without affecting other areas where you might need less volume.
