High Sensitivity Robust Low Noise Piezo Film Technology Shielded Cable The CM-01B Contact Microphone uses sensitive but robust PVDF piezo film combined with a low-noise electronic preamplifier to provide a unique sound or vibration pick-up with buffered output. The design minimizes external acoustic noise while offering extremely high sensitivity to vibration applied to the central rubber pad. The CM-01B is ideal for detecting body sounds. Broad Bandwidth High Sensitivity Excellent Impact Resistance Lightweight Low Cost Electronic Stethoscope Bone-conducted Sound Pickup General Purpose Contact Microphone Vibration/Impact
