Abstract
(EN)
A proximity sensor arrangement is provided comprising at least one first and at least one second acoustic transducer and at least one comparing means. The acoustic transducers are adapted to receive acoustic signals and convert the received acoustic signals into electric signals. The comparing means are adapted to compare the spectra received by the acoustic transducers. If the device comprising the proximity sensor arrangement is held at a user's ear, the signal received by the covered microphone is low-pass filtered due to human tissue and/or the presence of the human head, resulting in a spectral difference between several microphones. Furthermore a method is provided comprising the steps of receiving an acoustic signal at at least two locations distant from each other. In a second step, said received acoustic signals are converted into electric signals. Subsequently, the actual proximity and/or coverage situation is deduced from the spectral difference between the electric signals.
