Inventor of sound-related technology

as a graduate student developed computer tools for studying problem noise in the suburbs and investigated how to produce quieter computer printers; while working at Bell Labs developed devices for microphones and earphones and improved conference calling systems to eliminate echoes that some speakers produce; at University of Texas worked on on ways to reduce the level of noise that comes from transportation & discovered it was the shape of the highway barriers, not their composition, that effected noise levels;

Piezoelectric compositions; Noncontact position measurement system using optical sensors; Electret transducer for blood pressure measurement; Integrated capacitive transducer; Electret transducer with variable actual air gap; Electret transducer with a selectively metalized backplate; Electret transducer with variably charged electret foil; Electret transducer with variable electret foil thickness
