21. Sonnovation
Sonnovation's line of digital hearing aids includes technology such as the ability to "move" high frequency sounds like voiceless speech sounds to low frequency regions (because most people hear better in the low frequencies), and FM compatibility. Features include the ability to reduce noise by as much as 20 db, dual directional microphones, and multiple channels for optimizing gain and output when listening to speech. One model is a combination BTE /FM that can automatically switch to FM mode.
