The invention provides a method performed by an audio source device. The method obtains an input audio signal and determines a sound output level of a headset based on the input audio signal, a user volume setting, and a sound output sensitivity of the headset. The method determines whether the sound output level is above a threshold. In response to determining that the sound output level is above the threshold, a scalar gain is applied upon the input audio signal to produce an output audio signal for output by the headset. 本公开涉及用于自适应音量控制的方法和系统。一种由音频源设备执行的方法。该方法获取输入音频信号，并且基于输入音频信号、用户音量设定和头戴式耳机的声音输出灵敏度来确定头戴式耳机的声音输出水平。该方法确定声音输出水平是否高于阈值。响应于确定声音输出水平高于阈值，将标量增益应用于输入音频信号以产生用于由头戴式耳机输出的输出音频信号。
