Digital hearing aid is a hearing device that receives sound and digitizes it (breaks sound waves up into very small, discrete units) prior to amplification. And it built-in intelligence that allows them to discern between soft, but desirable sounds and louder, but unwanted noise. Such devices can amplify the former while neutralizing the latter for better performance in a variety of environments. They can divide into two categories, one is the programmable hearing aid and another one is the non-programmable hearing aid. 

For digital ear machine, "Channels" and "Bands" which are also some of the most misunderstood by users. A band is what is used to control volume in different frequencies and channels break up the frequency range into individual channels. In short, more bands and channels provide you with a more granular sound quality.
