1. A playback device comprising:
a plurality of temperature sensors;
at least one audio transducer;
one or more processors; and
a computer-readable memory storing instructions that, when executed by the one or more processors, cause the playback device to perform operations comprising:
obtaining temperature data from each of the plurality temperature sensors;
based on the temperature data, obtaining a temperature parameter for each of the plurality of temperature sensors, at least one of the temperature parameters indicating an increase in temperature;
for each temperature sensor, determining an amount of gain reduction to be applied to audio playback based on the temperature parameter; 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.
