    • Disclosed are methods and devices for controlling the state of a fan (104) of an electronic device (102) during audio output based in whole or in part on loudness data of a digital audio file. An audio data file is sampled (242) so that loudness data is determined (244) from the sample audio data. The loudness data may indicate (246) 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 (104) can be deactivated or slowed (250). In this way the noise of the fan (104) does not impair the user's audio experience. Alternatively, when the loudness data indicates that the audio output is high, the fan (104) can be activated or its speed may be increased (248). The predetermined loudness level of the audio output may have a value that is sufficiently high to mask fan noise.
    • 公开了用于在整个或部分地基于数字音频文件的响度数据的音频输出期间控制电子设备(102)的风扇(104)的状态的方法和装置。 音频数据文件被采样(242),从而从样本音频数据确定响度数据(244)。 响度数据可以指示(246)具有预定响度级别的音频数据文件的至少一部分。 例如,当响度数据指示音频输出为低时,风扇(104)可以被去激活或减慢(250)。 以这种方式,风扇(104)的噪声不会损害用户的音频体验。 或者,当响度数据指示音频输出为高时,可以激活风扇(104)或其速度可以增加(248)。 音频输出的预定响度水平可以具有足够高的值以掩盖风扇噪声。
