    摘要： Disclosed are methods and devices for controlling the state of a fan of an electronic device during audio output based in whole or in part on loudness data of a digital audio file. An audio data file is sampled so that loudness data is determined from the sample audio data. The loudness data may indicate at least one portion of the audio data file that has a predetermined loudness level. For example, when the loudness data indicates that the audio output is low, the fan can be deactivated or slowed. In this way the noise of the fan does not impair the user's audio experience. Alternatively, when the loudness data indicates that the audio output is high, the fan can be activated or its speed may be increased. The predetermined loudness level of the audio output may have a value that is sufficiently high to mask fan noise.
