153 – Physiological Sounds Microphone – TSD108

The Physiological Sounds Microphone (TSD108) connects to the DA100B/C General Purpose Transducer Amplifier (see hardware setup). The TSD108 can be used with the TSD120 Noninvasive Blood Pressure Cuff or as a stand-alone device.
 
Use with the Blood Pressure Cuff to record the Korotkoff sounds for easy determination of systolic and diastolic blood pressure (see Application Note #130 Blood Pressure Measurement). When used on its own, it can record a variety of acoustical signals, including heart sounds and sounds associated with rubbing or grinding (e.g. bruxism). The acoustical transducer element is a Piezo-electric ceramic disk which is bonded to the interior of a metallic circular housing.
