Weighted bioacoustic sensor and method of using same

A bioacoustic sensor, comprising:

• a housing comprising an interfacing portion configured to establish coupling with a body part during use;
• a transducer element coupled to the interfacing portion of the housing and configured to sense sounds produced by matter of biological origin, the transducer element configured to modulate or generate a signal in response to deformation of the transducer element;
• one or more conductors coupled to the transducer element;
• a mass element compliantly coupled to a surface of the transducer element;
• and
• intervening material disposed between the transducer element surface and the mass element, the intervening material allowing for differential motion between the transducer element surface and the mass element during excitation of the transducer element.
