| Zusammenfassung: | A method for detecting whether a personal audio device is proximate to an ear of a user, the method comprising: receiving a first microphone signal derived from a first microphone of the personal audio device and determining, from the first microphone signal, a first resonance frequency associated with an acoustic port of the first microphone, the first resonance frequency dependent on a first temperature at the first microphone; receiving a second microphone signal derived from an second microphone of the personal audio device and determining, from the second microphone signal, a second resonance frequency associated with an acoustic port of the second microphone, the second resonance frequency dependent on a second temperature at the second microphone and determining an indication of whether the personal audio device is proximate to the ear based on the first and second resonance frequencies. |
