Wearable physiological acoustic sensor

摘要

A wearable physiological acoustic sensor has an embedded and stacked acoustic sensing component architecture that inhibits motion-related impulse noise and environmental background noise, and provides good body sound capture, good patient comfort and an unobtrusive presence. The embedded and stacked component architecture also includes an environmental microphone that enables cancellation of background noise for further noise reduction.

主权项

1. A wearable physiological acoustic sensor, comprising:
a plaster having a top layer and a bottom layer; and an acoustic sensing component assembly including a component housing having a ceiling, a wall and a floor having a flange held between the top layer and the bottom layer, and further including a component stack embedded in the component housing having a body microphone configured to collect airborne body sounds received through an opening in the floor and in the bottom layer and an environmental microphone configured to collect environmental sounds received through an opening in the ceiling.
