153 - PHYSIOLOGICAL SOUNDS MICROPHONE - SS17L
The Physiological Sounds Microphone (SS17L) connects to the MP3X hardware unit. The SS17L can be used with the SS19L Noninvasive Blood Pressure Cuff or as a stand-alone device.
If you use it with the Blood Pressure Cuff, you can 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.
