Abstract
An acoustic sensing system for a motor vehicle includes a strain gauge mounted at a motor vehicle surface, and a sensing circuit operatively coupled to the strain gauge. The sensing circuit is configured and disposed to detect acoustic responses in a passenger compartment of the motor vehicle through the strain gauge.
Claims25
An acoustic sensing system for a motor vehicle comprising:
- a strain gauge mounted at a motor vehicle surface;
- and
- a sensing circuit operatively coupled to the strain gauge, the sensing circuit being configured and disposed to detect acoustic responses in a passenger compartment of the motor vehicle.
A motor vehicle comprising:
- a body including at least one motor vehicle surface that defines, at least in part, a passenger compartment;
- and
- an acoustic sensing system operatively coupled to the body, the acoustic sensing system including:
- a strain gauge mounted to the at least one motor vehicle surface;
- and
- a sensing circuit operatively coupled to the strain gauge, the sensing circuit being configured and disposed to detect acoustic responses in a passenger compartment of the motor vehicle.
