Noise reduction doesn’t really reduce noise; it reduces amplification in the frequencies where there is noise and no speech. If there is a fan running in the background, the hearing aid will not amplify it as much as it will speech, when the hearing aid finds both speech and noise at a frequency, you still get both. More advanced the hearing aids manage noise better, it breaks the frequencies up into smaller pieces.

There are two types of memories available on a hearing aid, manual and automatic, many hearing aids have a push button that allows you to have different settings for different situations such as quiet places, noisy places, and music or telephone. The hearing aid beeps when you push the button to let you know which memory you are using, advanced hearing aids can have memories that are automatic so instead of pushing a button, the hearing aid does it for you.

Feedback or that annoying whistling sound is the number one complaint people have about hearing aids. Most hearing aid wearers experience feedback when they put their hand over their ear, or use the phone, feedback Cancellation will take down the amount of feedback that you hear.

Bands are what we use to adjust the volume in a hearing aid, more bands means more control when we program the hearing aid to your hearing loss.

Channels are used to adjust the part of the hearing aid that keeps the sound from getting too loud. It can also refer to the hearing aid noise reduction system, more channels is definitely better.
