Cutting edge, state-of-the-art technology allows Apherma to deliver quality, advanced
digital hearing instruments that offers superior sound quality. Apherma's digital hearing
instruments outperform other digital hearing devices thanks to our high performance AD
(analog to digital) and DSP (digital signal processing) chips. These processing chips
implement complex sound processing algorithms to solve many of the common problems associated
with hearing impairment.
Apherma's patent-pending wide dynamic range compression technology solves the distortion problems associated with multi-channel digital hearing devices. It is no longer necessary to compromise precision of frequency shaping against unwanted distortion. Apherma's patent-pending directional processing can track and suppress the dominant noise source, detect and compensate changes between directional microphones, and automatically turn itself off when directional listening is not necessary. |
