Abstract :
A benchtest system has been developed for the calibration and performance evaluation of cardiac microphones. The system provides frequency spectra and signal-to-noise information and can be used as an absolute measure of cardiac microphone sensitivity. Benchtest results show good qualitative agreement with patient data.<>
