Abstract
A stethoscope having noise suppression features that make it suitable for use in high noise environments. The stethoscope includes ear pieces connected to signal processing components connected to a transducer in a chest piece that includes at least one suppression barrier extending from it. In at least one embodiment, the transducer is centered on the chest piece with the at least one suppression barrier centered around the transducer. The suppression barrier prevents surface waves resulting from environmental noise from reaching the transducer thus providing a higher quality signal to be processed and in turn listened to by the medical professional.
