An acoustic microphone used in most electronic
stethoscopes may have frequency characteristics not
suitable for the body sounds, especially for the low frequency
heart sounds. Other stethoscopes provide the internal body sounds not directly from the body surface,
but through the air layer between the body surface and the microphone. The 658 solves these problems
with the use of a piezopolymer film contact microphone which is the heart of the 658. The 658 has
wide frequency characteristics and enables you to detect the heart and lung sounds more precisely.
