Abstract
One example discloses an acoustic pairing device, comprising: an acoustic processor configured to receive a first acoustic signal and a second acoustic signal; a signal comparison module configured to identify a propagation delay or amplitude difference between the first and second acoustic signals; and a pairing module configured to output a pairing signal if the propagation delay or amplitude difference is between a first value and a second value. Another example discloses a method for acoustic pairing between a first device and a second device, executed by a computer programmed with non-transient executable instructions, comprising: receiving a propagation delay or amplitude difference between a first acoustic signal and a second acoustic signal; pairing the first and second devices if the propagation delay or amplitude difference is between a first value and a second value.
