摘要：
An ultrasonic wave is output from a speaker of a head-worn device. A microphone signal is obtained from a microphone of the head-worn device that senses the ultrasonic wave as it reflects off an ear of a user. Heart activity such as a heart rate of the user is determined based at least on the microphone signal. Other aspects are also described and claimed.
