Abstract Acoustic stethoscopes have low sound levels. Digital stethoscope overcomes this issue by amplifying body sounds electronically. Acoustic stethoscope can be changed into a digital stethoscope by inserting an electric capacity microphone onto its head. As the sound signals are transmitted electronically, it can be wireless and can provide noise reduction. Wireless transmission of heartbeat rate can be done using IOT techniques. Heart sounds received from the microphone are processed, sampled, digitized and sent wirelessly using the Internet of Things (IOT) techniques, so that multiple doctors can do auscultation and monitor conditions of the patient.
