2. Abstract Health Professionals use stethoscope to measure heart beats.
The loud sound in the work place often creates noise in headsets.
This create very faint sound of heart beats, which creates difficulties in diagnosis.
A valuable time has been wasted to count the heart rate rather observing the quality of heart beat.
Digital smart stethoscope in make this mechanical task easier.
It provide high definition audio and accurate monitoring.

3. Working
Digital smart stethoscope’s diaphragm sense the heart beats when brought closer to it.
This diaphragm signals are being transferred to microphone which convert sound into electrical signals.
This signals are being processed by microcontroller and which in turn amplify the sound, filter the noise and do precise calculation to display the output.
