具体实施方式
本申请的实施方式部分使用的术语仅用于对本申请的具体实施例进行解释，而非旨在限定本申请。
在当前音频播放终端设备中，安规EN50332法规要求在播放特制测试音源时，最大播放档位耳机声压应小于100dB(A计权)，保护档位耳机声压应小于85dB(A计权)。该听力保护手段单一，当用户所听音源的幅度比特制测试音源幅度大时，用户仍然有可能听到的瞬时声压大于100dB(A计权)，超过100dB(A计权)时，则一定程度上会损伤用户的听觉神经细胞，不仅瞬时声压大会造成听力受损，当用户在终端设备上长时间使用耳机时会产生累积声剂量，当前保护方法对长期使用耳机造成的累积损伤效应不能保护。
为了更好地保护用户听力，新的安规标准给出了两种可选的安规要求方案。其中方案一与现有要求一致，新的安规标准中推荐的方案二限定了长时间听音乐累积效应的声剂量大小。但当前的电子设备针对上述方案二尚未提供有效技术手段。
图1为现有相关技术提供的一种保护人耳听力的方法的流程图，该技术方案提供了一种保护人耳听力的方法，该方法包括：当耳机停止播放音频信号时，接收采集的环境噪声；对环境噪声进行分析，得到目标噪声声压级；根据预设的噪声声压 级与最大输出音量的映射关系，确定目标噪声声压级对应的最大输出音量；对耳机输出的音频信号的最大音量进行控制，使最大音量小于最大输出音量；接收实时监测到的人外耳通道内的实际声压数据；将实际声压数据与预设声压阈值进行比较；根据比较结果控制耳机输出音频的当前音量。本发明实施例能够将周围环境的噪声与耳机实际输出音量相结合来对耳机输出音量进行实时控制，使得耳机输出的音量能够对人耳的听力进行保护，不会造成任何损伤，也不影响音频的收听体验。
但是上述方案存在以下问题：
(1)该方案为了采集外耳道内的声音，需要在耳机腔体内增加声压传感器，对常规耳机无法兼容，同时会增加硬件成本。
(2)该方案至少需要在耳机上布设2个传声器，而当前电子设备3.5mm耳机接口仅能支持获取1路传声器数据。因此当前电子设备上的3.5mm耳机数据传输接口及协议不满足上述方案的需求，需定义及实现新的传输接口及协议。
(3)耳机腔体内监测到的声压与用户耳膜处实际听到的声压存在较大差异，在表征用户实际听到的声压大小时精度较差。
(4)该方案仅仅提出了对用户听音乐时耳朵听到的瞬时声压超标进行听力保护，而未实现针对用户长时间使用耳机而产生的累积听力损伤效应的保护。
本申请提供一种保护用户听力的方法，可以在不增加现有电子设备硬件器件的基础上，实现在用户使用耳机听音乐、看视频、听书、收听广播、玩游戏和/或通话等使用耳机场景下，在瞬时声压超标听力损伤以及长期使用耳机时累积听力损伤这两种损害用户听力的情形下，对用户的听力进行保护。
图2为本申请保护用户听力的方法一个实施例的流程图，如图2所示，上述保护用户听力的方法可以包括：
步骤201，在电子设备开启听力保护模式之后，当上述电子设备当前的声音输出模式为耳机输出时，获取当前帧音源数据。
具体地，电子设备可以根据音频通路当前寄存器或参数数据获取当前声音输出模式，如果上述电子设备当前的声音输出模式为喇叭或听筒，则电子设备自动关闭听力保护功能并提示用户当前为非耳机模式；如果上述电子设备当前的声音输出模式为耳机输出，则电子设备正常切入听力保护模式，获取当前帧音源数据。
步骤202，根据上述当前帧音源数据，获取上述电子设备连接的耳机输出的声压。
也就是说，本实施例可以根据当前帧音源数据，获取上述电子设备连接的耳机输出的声压，无需在耳机腔体内增加声压传感器，也不需要更改耳机数据传输接口及协议。
其中，上述电子设备连接的耳机可以为通过耳机线与上述电子设备连接的耳机，也可以为通过蓝牙与上述电子设备连接的蓝牙耳机，本实施例对上述电子设备连接的耳机的具体形态不作限定。
步骤203，将上述声压与预定的声压阈值进行对比。
其中，上述预定的声压阈值可以在具体实现时，根据系统性能和/或实现需求等自行设定，本实施例对上述预定的声压阈值的大小不作限定。
步骤204，如果上述声压大于预定的声压阈值，则进行瞬时声压超标预警和瞬时声压超标保护操作。
其中，上述瞬时声压超标保护操作可以是使用上述电子设备的用户预先设定的，上述瞬时声压超标保护操作可以包括：关闭播放、降低音量或用户设定的其他操作，本实施例对上述瞬时声压超标保护操作的具体操作不作限定。
也就是说，当上述声压大于预定的声压阈值时，电子设备会进行瞬时声压超标预警，并根据上述用户预先设定的操作，对电子设备进行关闭播放、降低音量或用户设定的其他操作。
上述保护用户听力的方法中，在电子设备开启听力保护模式之后，当上述电子设备当前的声音输出模式为耳机输出时，获取当前帧音源数据，根据上述当前帧音源数据，获取上述电子设备连接的耳机输出的声压，将上述声压与预定的声压阈值进行对比，如果上述声压大于预定的声压阈值，则进行瞬时声压超标预警，并对上述电子设备进行瞬时声压超标保护操作，从而可以在用户使用耳机进行听音乐、看视频、听书、听广播、游戏和/或通话等场景下，在瞬时声压超标时对用户的听力进行保护。
图3为本申请保护用户听力的方法再一个实施例的流程图，如图3所示，本申请图2所示实施例中，步骤202可以包括：
步骤301，获取上述耳机当前的使用场景。
其中，上述耳机当前的使用场景可以包括：音频播放、视频播放、游戏或通话等。
步骤302，根据上述当前帧音源数据，以及上述使用场景对应的通路上的音效改变及增益值，获取输出到上述电子设备的耳机接口处的数字信号值。
步骤303，根据上述数字信号值和上述电子设备的数电转换增益值获取输出到上述耳机接口处的电压值。
步骤304，根据上述电压值和上述耳机的电声转换系数获取上述耳机输出的声压。
具体地，在根据上述电压值和上述耳机的电声转换系数获取上述耳机输出的声压之前，还包括：在上述电子设备播放特制音源数据之后，获取上述电子设备的耳机接口处的电信号时域数据，并获取上述耳机输出的声信号时域数据；根据上述电信号时域数据和上述声信号时域数据获取上述耳机的电声转换系数。
具体地，图4为本申请保护用户听力的方法中获取电声转换系数一个实施例的示意图，如图4所示，在电子设备播放特制音源数据之后，可以使用电压测量设备获取上述电子设备的耳机接口处的电信号时域数据V t，并使用人工头测试获取上述耳机输出的声信号时域数据P t，然后分别对V t和P t进行快速傅里叶变换(fast fourier transform；以下简称：fft)，获得电信号频域数据V spec和声信号时域数据P spec，再将声信号频域数据P spec通过A计权网络转换为A计权声信号频域数据P specA，最后计算A计权声信号频域数据P specA与电信号频域数据V spec的比值，上述比值即为电声转换系数H e2a(f)。
本实施例中针对电子设备搭配的耳机会使用人头躯干模拟器来进行测试获取耳 机本身的电声传递函数，该传递函数表征了耳机接收到的电信号(由电子设备输出)到耳膜模拟位置处(人头躯干模拟器耳朵内部布设有声压传感器)的精确数值，精度较高。
这样，根据上述电压值和上述耳机的电声转换系数获取上述耳机输出的声压可以为：将上述电压值转换为电信号频域数据；根据上述电信号频域数据和上述电声转换系数，获取声信号频域数据；将上述声信号频域数据转换为声信号时域数据；然后根据上述声信号时域数据获取上述耳机输出的声压。
具体地，图5为本申请保护用户听力的方法中获取声压的一个实施例的示意图，如图5所示，可以对上述电压值(即电信号时域数据V t)进行fft变换，将上述电压值转换为电信号频域数据V spec，然后将上述电信号频域数据V spec乘以上述电声转换系数H e2a(f)，获得A计权声信号时域数据P tA，最后对上述A计权声信号时域数据P tA进行等效连续A声级计算，获得声压级计算值L PA。
本实施例可以根据当前帧音源数据，获取上述电子设备连接的耳机输出的声压，完全通过软件实现，无需在耳机腔体内增加声压传感器，也不需要更改耳机数据传输接口及协议。
图6为本申请保护用户听力的方法再一个实施例的流程图，如图6所示，本申请图2所示实施例中，步骤202之后，还可以包括：
步骤601，保存当前帧音源数据对应的声压。
具体地，可以将当前帧音源数据对应的声压存入存储器。
步骤602，根据保存的声压的历史数据，确定截至当前时刻累积产生的声剂量。
具体地，可以根据存储器中保存的声压的历史数据及声剂量计算方法，计算截至当前时刻累积产生的声剂量。

其中，上述预定的声剂量标准值可以是国际标准或国内标准规定的声剂量标准值，也可以是用户自定义的声剂量标准值。
步骤604，如果上述声剂量大于上述预定的声剂量标准值，则进行声剂量超标预警和声剂量超标保护操作。
其中，上述声剂量超标保护操作可以是使用上述电子设备的用户预先设定的，上述声剂量超标保护操作可以包括：提醒用户暂停使用耳机模式以避免听力受损，并建议用户休息X小时后再使用耳机模式，并执行关闭播放、降低音量、或用户设定的其他选项操作。
进一步地，步骤603之后，如果上述声剂量小于或等于上述预定的声剂量标准值，或者上述声剂量大于上述预定的声剂量标准值但用户强制电子设备继续播放，则电子设备继续播放下一帧音源数据，返回执行步骤201；如果上述声剂量大于上述预定的声剂量标准值并且用户选择关闭播放，则本次流程结束；另外，当上述用户正常使用完终端设备拔出耳机或关闭播放时，听力保护模式自动退出。
本实施例实现了在长时间连续听音乐时总声剂量超标损害用户听力的情形下，对用户进行预警及听力保护。
图7为本申请保护用户听力的方法再一个实施例的流程图，如图7所示，本申请图2所示实施例中，步骤201之前，还可以包括：
