This Small Business Technology Transfer (STTR)Phase I project seeks to develop a commercially viable, self-calibrating, piezoelectric micro-electro-mechanical systems (MEMS) microphone. The acoustical specifications of these microphones (measured by noise floor, linearity, sensitivity) will meet or… More

Improving the acoustical environment is critical in aeronautics. Airports and aeronautical systems manufacturers are facing ever-increasing demands to reduce noise levels. Aeronautical applications require the use of large arrays of high quality microphones with a large dynamic range. These arrays… More

DESCRIPTION (provided by applicant): Roughly 30 million Americans suffer from hearing loss and would benefit from some form of hearing augmentation. However, the hearing aid (HA) adoption rate is low, less than 25 percent [Marke, (2010)] and those who do a dopt wait more than 10 years before doing… More

This Small Business Technology Transfer (STTR) Phase II project will develop a microphone for the test and measurement (T & M) market that utilizes piezoelectric microelectromechanical systems (MEMS) technology. During Phase I of this project, feasibility was demonstrated by building and testing… More

Improving the acoustical environment is critical in aeronautics. Airports and aeronautical systems manufacturers are facing ever-increasing demands to reduce noise levels. Aeronautical applications require the use of high quality microphones with a large dynamic range, sometimes in large arrays. … More
