Abstract

The present invention relates to a device and a method for presence detection in the vicinity of a device. The device including an acoustic receiver and corresponding analyzing unit for analyzing the received signals, and an acoustic transmitter, the transmitter and received being configured to operate within a predetermined acoustic frequency range. The method including the steps of receiving and analyzing acoustic signals from the environment within said frequency range and evaluating the periodicity and volume of the signals and identifying frequency ranges and/or time windows with low risk for interference, the transmitter being configured to transmit a presence detection signal within the identified frequency range and time windows, the receiver receiving reflections from the transmitted presence detection signals from which the analyzing unit indicates the possible presence of a user.
