The Auditorium Infrared Sound System (ISS) transmits heart, lung, bowel, and Korotkoff sounds to a small or large audience with each person wearing a wireless HeartMan Infrared Headphone (HIH). Because of the HIH's comfortable binaural ear pieces and the internal speaker, the sounds are very similar to those heard with a stethoscope. For large auditoriums.
