Technologies used:

The Sontro Hearing Aids use directional microphones and advanced signal processing to manage noise coming from different directions. This feature, called Adaptive Directionality, allows wearers to follow conversations easily with their hearing aids. These new OTC hearing aids process sound using a technology called WDRC (Wide Dynamic Range Compression) to help expand the hearing range across 16 frequency channels. This type of sound compression technology makes soft sounds louder and loud sounds more comfortable, giving users easy listening and great sound quality. These devices also monitor the environment and automatically select the most appropriate sound mode to help wearers hear their best in a variety different listening situations.
