The electronic stethoscope needs to convert the electrical signal of the sound of the sound and then be amplified and processed for optimal listening. They are based on the same physical principles as acoustic stethoscopes.

The electronic stethoscope can also be recorded with a computer-assisted auscultation plan to record the heart's sound pathology or innocent heart murmurs.

Therefore, Doppler stethoscopes are particularly well suited for handling moving objects such as beating hearts.
