Abstract: An auscultation device that can be used for telemedicine consultations and real-time telemedicine monitoring. The digital stethoscope includes a detector of analog acoustic signals from the patient and a data processing system implemented via a secure encrypted web-protocol and accessible via the user interface of a progressive web-application on a portable computing device of the patient/physician with connected headphones. The acoustic signal detection device comprises a sequentially connected audio microphone, an analog signal pre-amplifier, an ADC, a microcontroller, and a battery. The microcontroller combines the signals from the ADC and the device status signals into a single packet and transmits it wirelessly to the data processing system. The software processing is carried out on the physician's or patient's device.
