1. A playback device comprising:
a plurality of temperature sensors;
at least one audio transducer;
one or more processors; and
data storage having instructions thereon that, when executed by the one or more processors, cause the playback device to perform operations comprising:
obtaining sensor data from each of the plurality temperature sensors, the sensor data indicating an increase in temperature;
for each temperature sensor, determining an amount of gain reduction to be applied to audio playback based at least in part on the sensor data; and
decreasing a gain of audio playback by a first amount, wherein the first amount comprises the largest gain reduction from among the gain reductions determined for each of the temperature sensors.
