The acoustic stethoscope is the earliest stethoscope and a medical diagnostic tool that most people are familiar with. This kind of stethoscope is a symbol of the doctor, and the doctor wears it on the neck every day. Acoustic stethoscopes are the most commonly used. The electronic stethoscope uses electronic technology to amplify the sound of the body and overcomes the high noise bug of the acoustic stethoscope. The electronic stethoscope needs to convert the electrical signal of the sound to the sound wave, which is then amplified and processed to get the best listening. Compared with acoustic stethoscopes, they are based on the same physical principles.
The electronic stethoscope can also be used with the computer-aided auscultation plan to analyze the recorded heart sound pathology or innocent heart murmurs.
