<p>A method for determining a heartbeat rate of a user from an acoustic heartbeat signal, a heartbeat rate measuring device, and a mobile device are described. The heartbeat rate measuring device (200), comprising: a microphone (201) adapted to detect an acoustic heartbeat signal of a user in an ear of the user, a sampling unit adapted to sample the heartbeat signal with a predefined sampling rate, and a correlation unit (207) providing a plurality of heartbeat rate values, the correlation unit being adapted to correlate the sampled heartbeat signal with each of the plurality of heartbeat rate values, and to determine the heartbeat rate value with the best matching correlation.</p> |
