If the diaphragm is placed on the patients' chest, acoustic airwaves are produced by the vibration of the plastic diaphragm which travel through the tubing to the listeners' ears. There was one model that had built in functionality in the tubing to tighten ear tip insertion pressure. It's because ear tips are small and inexpensive. When the diaphragm is placed against the patient's skin, body sounds vibrate the diaphragm, creating acoustic pressure waves which then travel to the listener's ears.

The design for this device has a lot of similarities with an old hearing aid device called an "ear trumpet". The analog audio voltage fluctuations are fed through a circuit component called the analog to digital convertor, which changes the incoming voltages to digital snapshots 44, 100 times a second, assuming a 44. This is especially true for the "ear bud" style of headsets that are inserted into the ear. Digitizing Stethoscopes. For newborns it is very fast. PubMed Central (PMC), 1 Mar.
