Low-Noise Directional Hearing Aid Microphone
Using Optical Sensing and Electronic Feedback
The primary aim of this project is to develop technology for the creation of directional microphones for hearing aids that have essential inaudible thermal and electronic noise. This effort will extend results obtained under our BRP through optimized microphone diaphragm designs, low-noise optical sensing, and the incorporation of active electronic damping to produce directional microphones having barely audible noise floors. Apr 2008 - Mar 2011.

Sensing and Processing for Directional
Hearing Aids
The aim of this effort is to develop revolutionary technology for hearing aids that will lead to a marked improvement in the ability of the hearing impaired to understand speech in noisy environments. Our focus is on improving the technology of acoustic sensing and processing of signals so as to minimize the influence of unwanted sounds. This effort has three closely interrelated areas of technology development: novel directional microphones, novel optical readout, and novel signal processing. Sep 2003 - Aug 2008
