The present invention includes a system and method for detecting a pulse. The system includes a sound sensor unit device having a self-adhesive material and a sensor body with a sound chamber, a power source, a MEMS microphone and a transmitting device. The sensor unit wirelessly sends a first signal to a remote unit adapted to receive the first signal. The remote unit includes a housing having a receiver, an audio/visual interface unit whereby the audio visual interface unit processes the first signal and translates the first signal into output formats to an audible signal and to a visual display signal, and a power source in electrical communication with the receiver and the audio visual interface unit
