An microphone used in most electronic stethoscopes may have frequency characteristics not suitable for 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 electronic stethoscope solves these problems with the use of its piezopolymer film contact microphone, which is at the heart of the electronic stethoscope. The electronic stethoscope has wide frequency characteristics, enabling user to detect the heart and lung sounds more precisely.
