Accoustically transparent occlusion reduction system and method

Jorge Patricio Mejia (Inventor), Harvey Albert Dillon (Inventor), Michael John Amiel Fisher (Inventor)

Research output: Patent


A system and method that reduces the perceptual effect resulting from ear occlusion include an electro-acoustic feedback network that produces phase canceling sounds in the ear, where a receiver and a microphone are located. A control mechanism controls the response of the feedback network to minimize distortion in the ear while maintaining a desired frequency response for external signals. Devices producing the external signal include hearing aids, personal sound devices, in ear monitors, communications headsets and hearing protectors. The integration of the above with these devices improves a user's perception of their own voice.
