An electronic stethoscope lacking an earpiece assembly can include a chestpiece base. The base can include a diaphragm, a transducer, a computer readable storage medium, and a transceiver. The transducer can detect analog auscultatory sounds from an auscultatory source and convert the sounds to a digital encoding. The encoding can be transmitted to a proximate or remote computing device via a secure communication channel. The earpiece assembly can be a cavity for transmitting the analog auscultatory sound from the base to the ear canal of a user.
