Design of electronic stethoscope to prevent error analysis of heart patients circumstances

Stethoscope is an acoustic medical device widely use by doctors to listen to the sound of the heartbeat. Based on the sound of the heartbeat, the doctor can analyze the patient´s heart condition. Acoustic stethoscope has a weakness in low sensitivity of sound that can be heard and vulnerable to external noise interference. The Addition of an electronic circuits in acoustic stethoscope will strengthen the heart rate signal. The addition of electronic circuits in the acoustic stethoscope is often called an electronic stethoscope. Electronic stethoscope utilizes a microphone and amplifier and electronic circuit as modifiers of the acoustic signal into digital. Electronic stethoscopes can cover the shortage of the less sensitive acoustic stethoscope and can minimize error analysis of the state of the patient´s heart. To analyze the state of the heart beat, the output produced by the electronic stethoscope can be visualized in the form of the spectrum and played repeatedly by doctors with an audio player application.
