Acoustic sound is transformed into electronic impulses using a digital stethoscope, which can then be amplified for optimal listening. Digitalized, processed, and sent electronic signals from a digital stethoscope can be received by a laptop or personal computer. The three different modules that make up the Digital Stethoscope are data collecting, pre-processing, and signal processing. The data acquisition model, which focuses on buffering, amplification, and filtering of auscultated sounds and converts acoustic sound to digital signal, is made up of a piezoelectric sensor and a microphone. The pre-processing module's job is to filter digital signals to get rid of any artefacts. Data for a diagnostic decision are gathered and bundled in high order classification with the aid of a signal processing module.
