Abstract
Sounds sensed by a microphone of a device include sounds from a cooling fan of the device that varies based on the speed of the cooling fan, and other sounds used by a program of the device such as voice inputs. The sound level of sounds used by the program is determined, and the speed of the fan is adjusted so that a desired cooling level is attained while keeping the fan speed low enough that the noise from the fan does not interfere with the sounds used by the program.
