Digital Hearing Aid

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 digital ear machine 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 hearing aid, “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. We can see 2 Channels, 4 Channels, 6 Channels, 8 Channels and even 32 Channels digital hearing aid sound amplifier on the market, more channels will more accurate.

Analog Hearing Aid

For many years, analog hearing aids were the only kind you could get. Today, analog devices are still available and offer a number of benefits for users.

Analog hearing aids work in a similar way to a microphone hooked up to a speaker. The hearing aid picks up outside sound, amplifies it, and outputs the same sound at a louder volume. Unlike digital hearing aids, analog hearing aids amplify all sound equally. They aren’t able to separate foreground and background noise or isolate certain types of sound.

That said, many analog hearing aids are still programmable, and even offer multiple listening modes for different environments. Some people also think analog hearing aids sound “warmer” because the sound isn’t digitally processed.
