How important? Which brands have them?
Thank you!
It’s a Bernafon processing ideology. It suggests that other manufacturers’ breaking down the signal into several channels and processing them differently introduces quantization and temporal errors. Bernafon keep the signal sampled and amplified as cleanly as possible, they claim to have better results for the preservation of high frequency sounds. The downside is that the aids can sound Chirpy and may feedback a little more than similar products using different processing strategies.
So, Bernafon only.
