  An electronic stethoscope overcomes the low sound levels by electronically amplifying the body sounds. Electronic stethoscopes convert the acoustic sound waves obtained through the chest piece into electrical signals which can then be amplified for optimal listening.
  Eko stethoscopes use Bluetooth to pair with smartphones and tablets through the Eko App (available on iOS and Android). Through the Eko App, clinicians can listen to, visualize, and share auscultations of the same quality as if they were listening directly through stethoscope earpieces.
  The working concept of the proposed wireless bluetooth stethoscope circuit is rather simple:
  The heart beat sound pulses hit the MIC, which converts them into equivalent electrical pulses.
  These electrical pulses are amplified by an integrated op amp amplifier stage to appropriate levels.
  This week 3M unveiled a stethoscope with a built-in Bluetooth radio that aims to enable physicians to detect heart murmurs and other afflictions by sending the data recorded by the device, sending it to a PC and amplifying the sound. The device is known as the Littmann 3200.
  When your Stemoscope is working, use your finger to tap/knock the diaphragm. If you can hear a loud dub sound with your earphones and high volume when you tap/knock, the Stemoscope works well. Heart sounds are easy to be detected. You may listen to your heartbeats.
  iStethoscope Pro makes your phone work just like a stethoscope. It amplifies and filters quiet sounds. You can hear any quiet noise – including your heart beat – if you place the iPhone microphone in the right place.
  Every time the valves in your heart open and close to let blood flow through, it makes a 'dub-dub' sound. If you've ever wondered what your heart sounds like you can listen to your own heartbeat with a stethoscope made from rubber tubing, 2 funnels and a balloon.
