VitaSound Neuro-Compensator Applies Brain Science To A Unique And Potentially Revolutionary New Sound Processing System For Hearing Aids

VitaSound Audio, Inc., a young hearing-aid company in Canada, has come up with an entirely new approach to sound-processing software for hearing aids that could fundamentally change the way we think about compensating for damaged hearing. I got a demo of VitaSound’s Neuro-Compensator technology several months ago and have been struggling ever since to come up with appropriate words to describe it. “Unique,” “new,” “unprecedented” and “potentially revolutionary” are the best I can do for starters.

The Neuro-Compensator sound processing system is based on nearly two decades of research at McMaster University in Hamilton, Ontario, into how the human brain comprehends the signals processed by the auditory system, from the middle ear through the auditory nerve. The researchers mapped the signals produced by hundreds of auditory inputs processed by people with healthy hearing, coming up with a hugely complex model of “normal” hearing response to sounds ranging from human speech to music to pure tones to rush-hour traffic to cocktail-party noise. Then they developed the Neuro-Compensator software to compare the norm to that of a person with damaged hearing, and to produce a hearing-aid amplification program that not only amplifies the frequencies where hearing has been lost, but also filters out sounds that a healthy auditory processing system would normally suppress. The benefit is better comprehension because the system constantly adjusts amplification at multiple frequencies in response to different sounds to match the auditory profile of a normal, healthy auditory system responding to various listening environments.
