A circuit and method for determining an ambient temperature for an electronic device having a loudspeaker are described. An amplifier drives the loudspeaker and first circuitry is configure to determine an overall temperature of the loudspeaker or the amplifier. Second circuitry is configured to determine a change in temperature of the loudspeaker or the amplifier resulting from power dissipated in the loudspeaker or the amplifier. Third circuitry is configured to subtract a signal representative of the change in temperature from a signal representative of the overall temperature and output a signal representative of the ambient temperature for the electronic device.

Temperature sensing

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.

Acoustic pairing

In a sound reproduction or recording system an audio signal is multiplied by a gain factor (z) which is dependent on the input level (y). The dependence of the gain factor on input level is chosen such that unvoiced phonemes are at least 6 dB, preferably at least 12 dB more enhanced than voiced phonemes, where preferably the average gain is less than 6 dB. This improves the intelligibility.
