Abstract
Aspects of the present disclosure provide techniques, including devices and systems implementing the techniques, for detecting a current state of a wearable audio device of a user. One example technique for detecting the current state of the wearable device generally includes transmitting, with a driver, at least one pulsed signal associated with the current state, receiving, at a microphone, a received signal of the at least one pulsed signal, determining an acoustic signal associated with the current state based on the received signal, determining a difference between the acoustic signal associated with the current state and a prior acoustic signal associated with a known state, and determining the current state of the wearable audio device based, at least in part, on a comparison of the difference to a threshold. In some aspects, the at least one pulsed signal comprises at least one pulsed ultrasonic wavelet.
