本实施例的执行主体为上述通信架构中的终端10，也可以为无线耳机中的主耳机。在本步骤中，左右耳机分别通过复用通话的Mic采集环境噪声。当执行主体为终端时，左右耳机将采集到的环境噪声发送至终端，当执行主体为主耳机时，从耳机将采集到的环境噪声发送至主耳机。
S102：对所述第一环境噪声和所述第二环境噪声进行频响分析，得到平衡曲线；
在本步骤中，对左右耳机采集的环境噪声进行频响分析，得到第一环境噪声对应的第一频响曲线和第二环境噪声对应的第二频响曲线，即得到各环境噪声对应的分贝与频率的比值。对第一频响曲线和第二频响曲线进行平衡，得到平衡曲线。由于该平衡曲线平衡了第一环境噪声和第二环境噪声，据此计算得到的左右耳机的EQ补偿参数可以达到左右耳机增益均衡的效果。
作为一种优选实施方式，对于平衡曲线中的每个频点，可以取第一频响曲线和第二频响曲线在该频点对应的分贝的平均值，即本步骤可以包括：确定所述第一环境噪声对应的第一频响曲线和所述第二环境噪声对应的第二频响曲线；对所述第一频响曲线和所述第二频响曲线进行均值化处理得到所述平衡曲线。当然也可以采用其他平衡方式，例如，为主耳机和从耳机分别分配权重系数，平衡曲线中的每个频点对应的分贝值，为第一频响曲线中该频点的分贝值与主耳机对应的权重系数的乘积和第二频响曲线中该频点的分贝值与从耳机对应的权重系数的乘积的加权值。主耳机的权重系数可以大于从耳机的权重系统，主从耳机的权重系数之和为1。
S103：根据所述平衡曲线计算所述第一环境噪声对应的第一EQ补偿参数和所述第二环境噪声对应的第二EQ补偿参数，以便所述左耳耳机利用所述第一EQ补偿参数、所述右耳耳机利用所述第二EQ补偿参数进行降噪处理；
在本步骤中，分别确定左右耳机需要进行补偿的频点，具体的，过大的波峰需要减少，而过小的波谷则需要增加。根据平衡曲线确定每个需要进行补偿的频点各自需要进行增加或者减多少分贝的增益。每个频点和每个增益的值与EQ补偿参数存在对应关系，因此，可以确定第一环境噪声对应的第一EQ补偿参数和第二环境噪声对应的第二EQ补偿参数。当执行主体为终端时，终端将第一EQ补偿参数发送至左耳耳机，将第二EQ补偿参数发送至右耳耳机。当执行主体为主耳机时，主耳机向从耳机发送从耳机对应的EQ补偿参数。
左右耳机分别将第一EQ补偿参数和第二EQ补偿参数加入待播放音频信号中以进行调节。此处对于待播放音频信号的内容不作限定，且播放时长也不作限定。在具体实施中，待播放音频信号可以包含有一个音频文件或者多个音频文件。为了避免频繁进行S101至S103的步骤，在一种具体实施方式中，如果两个音频文件的播放间隔小于预设值，则在播放完第一个音频文件后，主从耳机直接将当前EQ补偿参数作为下一个音频文件的播放时降噪处理的调节参数。也可以在每播放完一个音频文件就视为完成一次降噪，然后进入下一个降噪周期，即重新执行S101至S103。
当然，本实施例还可以由用户进行手动触发，即用户可以在终端上设置无线耳机处于平衡模式，即本实施例还包括：当接收到增益平衡命令时，设置当前模式为平衡模式，并执行所述获取左耳耳机采集的第一环境噪声和右耳耳机采集的第二环境噪声的步骤。
需要说明的是，对于上述增益平衡命令，可以由终端发送至主耳机，由主耳机转发至从耳机，当然也可以由终端分别发送至主从耳机，在此不进行具体限定。
本申请实施例提供的降噪方法，左右耳机分别通过复用通话麦克风采集环境噪声，即第一环境噪声和第二环境噪声，据此计算平衡曲线，并根据该平衡曲线分别计算左右耳机需要补偿的EQ补偿参数。由于平衡曲线是根据左右耳机分别采集的环境噪声计算得到的，根据该平衡后的曲线计算得到左右耳机EQ补偿参数可以达到左右耳机增益均衡的效果，提高用户实际使用体验。

S205：根据每个所述第一频点和在每个所述第一频点上所述平衡曲线与所述第一频响曲线的差值确定所述第一环境噪声对应的第一EQ补偿参数；所述主耳机根据每个所述第二频点和在每个所述第二频点上所述平衡曲线与所述第二响曲线的差值确定所述第二环境噪声对应的第二EQ补偿参数。
在本步骤中，将在第一频点上平衡曲线与第一频响曲线的差值确定为该第一频点需要补偿的分贝值，即增益，根据每个第一频点和每个第一频点对应的增益可以确定第一EQ补偿参数。将在第二频点上平衡曲线与第二频响 曲线的差值确定为该第二频点需要补偿的分贝值，即增益，根据每个第二频点和每个第二频点对应的增益可以确定第二EQ补偿参数。
