The TSD108 interfaces with the DA100C general-purpose transducer amplifier to measure a wide array of physiological sounds. Most commonly, the TSD108 is used to measure heart sounds or Korotkoff sounds. When the TSD108 signal is recorded along with the TSD120 blood pressure cuff signal, the Korotkoff sounds vividly mark the systolic and diastolic blood pressure. The TSD108 can also record the sounds associated with rubbing or grinding (e.g., Bruxism). To listen to the physiological sounds with headphones as they are recorded, pipe the TSD108 signal through the STM100C stimulator module. The acoustical transducer element is a piezo-electric ceramic disk, which is bonded to the interior of a metallic circular housing.
