Abstract
An earphone includes a loudspeaker, a microphone, a housing supporting the loudspeaker and microphone, and an ear tip surrounding the housing and configured to acoustically couple both the loudspeaker and the microphone to an ear canal of a user, and to acoustically close the entrance to the user's ear canal. A processor receives input audio signals from the microphone, detects peaks having a frequency of around 1 Hz in the input audio signals, based on the detected peaks, computes an instantaneous heart rate, measures a frequency of an oscillation within the instantaneous heart rate, and based on the frequency of the oscillation, computes a rate of respiration.
