Title:
EAR MICROPHONE APPARATUS AND METHOD
Document Type and Number:
WIPO Patent Application WO2002080615
Kind Code:
A3
Abstract:
A detection system. The detection system includes a housing (150,150') positionable with respect to an ear of a person and a microphone (34, 34') disposed with respect to the housing for at least partial insertion into the ear of a person. The microphone is operable to detect a change in air pressure within the ear while the person makes an initiating action and to produce an electrical signal corresponding to the internally detected change in air pressure. A processing circuit (14, 14', 14", 36, 36', 42) is coupled to the microphone for processing the electrical signal to produce a corresponding output. Various alternative systems and sensors for use in detecting changes within the ear are also disclosed.
