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.

Abstract
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.

17. A wearable physiological acoustic sensor, comprising:
-
an acoustic sensing component housing having a ceiling, a wall and a floor forming an enclosure and a mounting flange circumnavigating the housing; a plaster having a groove holding the mounting flange; and an acoustic sensing component stack within the enclosure having a body microphone configured to collect airborne body sounds through aligned openings in the floor of the housing and the plaster and an environmental microphone configured to collect environmental sounds received through an opening in the ceiling of the housing.
