为了便于理解，首先介绍本申请涉及的术语。
1、风噪
无外声场时，设备由具备一定速度和一定方向的风引起的等效声压。
本公开中的风噪测量方法的测量环境应满足以下要求：
测试环境应为自由场；
测试环境的噪声不应对测试结果造成影响；
测试环境内的自然风速应为0m/s；
若是在房间中对风噪进行测量，则测试所使用房间的尺寸相对于风道和被测终端设备应足够大，且不对测试时的气流造成额外的影响。
下面参考附图对本公开实施例所提供的风噪测量方法/装置/设备及存储介质进行详细描述。
图1a为本公开实施例所提供的一种风噪测量方法的流程示意图，该方法由被测终端设备执行，如图1a所示，该风噪测量方法可以包括以下步骤：
步骤101、针对不同风速、不同风向，分别采集第一测试环境下的信号数据，并向测试设备发送第一测试环境下的信号数据，以使测试设备确定不同风速、不同风向的风对被测终端设备音频质量的风噪影响；或者，在不同风速、不同风向下，向声音采集设备播放音频测试信号，以由声音采集设备针对不同风速、不同风向，分别采集第二测试环境下的信号数据。
其中，在本公开的一个实施例之中，该第一测试环境可以包括：
仅由风发生器向被测终端设备施加具备风速和风向的风；
由声源设备向被测终端设备播放音频测试信号，且由风发生器向被测终端设备施加具备风速和风向的风；
仅由声源设备向被测终端设备播放音频测试信号。
基于此，在本公开的一个实施例之中，上述的不同风速、不同风向对应的第一测试环境下的信号数据可以包括：
仅施加风时，被测终端设备采集到的纯噪声信号数据X1；
播放音频测试信号且施加风时，被测终端设备采集到的带噪环境下音频测试信号数据Y1；
仅播放音频测试信号时，被测终端设备采集到的安静环境下音频测试信号数据Z1。
以及，在本公开的一个实施例之中，被测终端设备针对不同风速、不同风向采集到第一测试环境下的信号数据后，可以将该第一测试环境下的信号数据发送至测试设备，以由测试设备确定不同风速、不同风向的风对被测终端设备音频质量的风噪影响。需要说明的是，本公开中，基于被测终端设备采集的第一测试环境下的信号数据所确定出的风噪影响主要为：当被测终端设备作为信号发送端时，风噪在被测终端设备采集音频信号时对其的影响。
具体而言，在本公开的一个实施例之中，当终端设备作为信号发送端时，其通常需要先采集音频信号，并再将采集的音频信号发送至信号接收端。例如，当用户A正利用自己的手机A通过用户B的手机B与用户B通话时，若当前用户A正在说话，则此时手机A为信号发送端，手机B为信号接收端，其中，手机A需要先采集用户A发出的声音并形成音频信号，并将该音频信号发送至信号接收端(即手机B)，以便手机B向用户B播放对应的音频信号。基于此，本公开中，“被测终端设备针对不同风速、不同风向，分别采集第一测试环境下的信号数据”这一场景具体就是模拟被测终端设备作为信号发送端时采集信号的场景。由此，基于被测终端设备采集的第一测试环境下的信号数据所确定出的风噪影响应当为：当被测终端设备作为信号发送端时，风噪在被测终端设备采集音频信号时对其的影响。
进一步地，需要说明的是，本公开对上述被测终端设备的形式不做限定，如该被测终端设备可以为头戴式、免提式、或者手持式。以及，在本公开的一个实施例之中，上述上述风发生器应满足以下要求：
该风发生器产生的风和自然风特性接近，并且能在测试过程中稳定工作；
风发生器的噪声不会对测试结果造成影响，且在测试需求的风速下都可以稳定工作；
风发生器的风道的尺寸相比被测终端设备的尺寸应足够大，以足够完全覆盖被测终端设备附近产生的湍流，确保测试环境和自然风环境尽量一致。
以及，示例的，在本公开的一个实施例之中，该风发生器例如可以为短装置用径流式风扇或长装置用轴向风扇。
在本公开的一个实施例之中，上述的声源设备可以为人工嘴和/或扬声器。其中，人工嘴用于输出模拟人声的音频测试信号，扬声器用于输出非人声形式的音频测试信号。以及，当声源设备为不同设备时，其向被测终端设备播放音频测试信号的方法也会有所不同。
具体的，声源设备向被测终端设备播放的音频测试信号为声源设备基于从其他设备处获取到的所需 要播放的音频测试信号确定得到；其中，响应于声源设备为扬声器，该声源设备向被测终端设备播放的音频测试信号为：声源设备从其他设备处获取到的所需要播放的音频测试信号；也即是，当声源设备为扬声器时，声源设备从其他设备处获取到所需播放的音频测试信号之后，会直接向被测终端设备播放该音频测试信号。
响应于声源设备为人工嘴，声源设备向被测终端设备播放的音频测试信号为：声源设备基于环境噪声对从其他设备处获取到的所需要播放的音频测试信号进行提升补偿之后的信号。其中，根据隆巴德效应(Lombard effect)可知，在实际情况下，当外界环境噪音较大时，人发声时会自觉升高音量，基于此，当声源设备为人工嘴时，为了确保其能够精确模拟人发声，其在向被测终端设备播放音频测试信号之前，需要先基于环境噪声对从其他设备处获取到的所需要播放的音频测试信号进行提升补偿，并再向被测终端设备播放提成补偿之后的信号。
其中，在本公开的一个实施例之中，声源设备可以利用如下公式来基于环境噪声对从其他设备处获取到的所需要播放的音频测试信号进行提升补偿：
Figure PCTCN2022128763-appb-000001
其中，I为环境噪声下对从其他设备处获取到的所需要播放的音频测试信号的提升补偿两(单位：dB)，N为声源设备测得的A计权长期噪声。
再进一步地，在本公开的一个实施例之中，被测终端设备也可以在不同风速、不同风向下，向声音采集设备播放音频测试信号，以由声音采集设备(如人工耳)针对不同风速、不同风向，分别采集第二测试环境下的信号数据，并将第二测试环境下的信号数据发送至测试设备，以使测试设备确定不同风速、不同风向的风对被测终端设备音频质量的风噪影响。
其中，上述的第二测试环境可以包括：
仅由风发生器向被测终端设备施加所述风速和所述风向的风；
由被测终端设备向声音采集设备播放音频测试信号，且由风发生器向被测终端设备施加所述风速和所述风向的风；
仅由被测终端设备向声音采集设备播放音频测试信号。
基于此，第二测试环境下的信号数据可以包括：
仅施加风时，声音采集设备采集到的纯噪声信号数据X2；
播放音频测试信号且施加风时，声音采集设备采集到的带噪环境下音频测试信号数据Y2；
仅播放音频测试信号时，声音采集设备采集到的安静环境下音频测试信号数据Z2。
以及，需要说明的是，在本公开的一个实施例之中，上述的基于被测终端设备采集的第二测试环境下的信号数据所确定出的风噪影响主要为：当被测终端设备作为信号接收端时，风噪在被测终端设备播放音频信号时对其的影响。
具体而言，在本公开的一个实施例之中，当终端设备作为信号接收端时，其通常需要先接收信号发送端发送的音频信号，并再播放该音频信号。例如，当用户A正利用自己的手机A通过用户B的手机B与用户B通话时，若当前用户B正在说话，则此时手机A为信号接收端，手机B为信号发送端，其中，手机B需要先采集用户B发出声音并形成音频信号，并将该音频信号发送至信号接收端(即手机A)以便手机A向用户A播放对应的音频信号。基于此，本公开中，“被测终端设备在不同风速、不同风向下，向声音采集设备播放音频测试信号，以由声音采集设备针对不同风速、不同风向，分别采集第二测试环境下的信号数据”这一场景具体就是模拟被测终端设备作为信号接收端时播放信号的场景。由此，基于被测终端设备采集的第二测试环境下的信号数据所确定出的风噪影响应当为：当被测终端设备作为信号接收端时，风噪在被测终端设备播放音频信号时对其的影响。
以下对本公开实施例的方法中声音采集设备、风发生器、声源设备、被测终端设备、测量设备之间的连接关系进行介绍。图1b和图1c为本公开实施例所提供的风噪测量时各设备之间的连接关系示意图。 如图1b和图1c所示，风发生器、声源设备、声音采集设备均可以朝向被测终端设备设置，其中，风发生器用于向被测终端设备施加不同速度、不同方向的风，声源设备可以朝向被测终端设备播放音频测试信号，声音采集设备可以采集被测终端设备播放的音频测试信号。以及，该被测终端设备可以安装在转台或支架上，该被测终端设备的参考点可以在转台或支架的中轴线上，且风发生器主轴方向可以对准该被测终端设备的参考点，其中，该被测终端设备的参考点可以是被测终端设备的任一点，如可以是被测终端设备的中心点。以及，在测试风噪时，还可以根据需要转动转台或支架以调整被测终端设备与风发生器、声源设备、声音采集设备之间的角度，如可以调整被测终端设备与风发生器、声源设备、声音采集设备之间的水平夹角和垂直夹角，其中，通过调整被测终端设备与风发生器之间的角度可以调整测试时的风向。
进一步地，参考图1b和1c，被测终端设备可以与测试设备连接，用于向测试设备输出第一测试环境下的信号数据，声音采集设备也可以与测试设备连接，用于向测试设备输出第二测试环境下的信号数据。
以及，需要说明的是，上述图1b模拟的是“被测终端设备与其他设备之间直接进行音频信号交互”的场景，上述图1c模拟的是“被测终端设备作为外接设备与其他设备进行音频信号交互，或者，被测终端设备与其他设备之间通过通信***进行音频信号交互”的场景(即被测终端设备与其他设备未直接进行音频信号交互的场景)。
还需要说明的是，在本公开的一个实施例之中，在测量风噪时，应当使得测量环境尽可能地接近于真实环境下设备的情况，如接近于真实环境下声学情况和风噪情况。以及，由于风噪声的本质为压力波动，因此，在测量过程中，风发生器向被测终端设备施加风时，应当小心避免因达到过载点而损坏被测终端设备从而影响后续测量过程。
综上所述，本公开实施例提供的风噪测量方法之中，针对不同风速、不同风向，被测终端设备会分别采集第一测试环境下的信号数据，并向测试设备发送第一测试环境下的信号数据，以使测试设备确定不同风速、不同风向的风对被测终端设备音频质量的风噪影响；或者，在不同风速、不同风向下，被测终端设备会向声音采集设备播放音频测试信号，以由声音采集设备针对不同风速、不同风向，分别采集第二测试环境下的信号数据，其中，声音采集设备采集到第二测试环境下的信号数据后，会发送至测试设备，以使测试设备确定不同风速、不同风向的风对被测终端设备音频质量的风噪影响。由此可知，本公开提供了一种适用于终端设备的风噪测量方法，可以用于测量风噪对各类型终端设备的影响。

其中，在本公开的一个实施例之中，被测终端设备通过向测试设备发送第一测试环境下各个声道对应的信号数据，以由测试设备基于第一测试环境下各个声道对应的信号数据确定不同风速、不同风向的风对被测终端设备的各个声道音频质量的风噪影响。
由上述步骤可知，本公开中的风噪测量方法还可以用于测量不同风速、不同风向的风对被测终端设备的多声道音频测试信号的风噪影响，则其适用性较广。

步骤302、向测试设备发送未开启抗噪模式时不同风速、不同风向对应的第一测试环境下的信号数据，以及不同抗噪模式下不同风速、不同风向分别对应的第一测试环境下的信号数据。

具体的，在本公开的一个实施例之中，上述的基于测量结果确定不同风速、不同风向对被测终端设备音频质量的风噪影响的方法可以包括以下任一种或任多种：
第一种：针对不同风速，利用所有风向下对应的最低的信号质量参数来表示被测终端设备在对应风速下的通信质量。
例如，在风速3m/s下，针对三个不同风向分别得到了测量结果，其中，该三个风向分别为风向一、风向二、风向二；以及，假设风向一对应的测量结果中的SNR的值小于风向三对应的测量结果中的SNR的值小于风向二对应的测量结果中的SNR的值，即，在风速3m/s下，所有风向下对应的最低SNR的值为风向二对应的测量结果中的SNR的值，此时可以利用风向二对应的测量结果中的SNR的值来表示被测终端设备在对应风速下的SNR通信质量。
第二种：将各个风向对应的测量结果中满足预设条件的所有测量结果对应的最大风速确定为各个风向下可支持的最大风速，将所有风向下可支持的最大风速中的最小风速确定为所述被测终端设备可支持的最大风速。
其中，该预设条件可以是根据测试的不同阶段以及不同需求灵活性设置的，例如，该预设条件可以为风噪失真率低于特定值等。
示例的，假设风向一下满足预设条件的测量结果为：风速1m/s对应的测量结果、风速3m/s对应的 测量结果。则此时可以确定风向一下可支持的最大风速为：3m/s；同理的，假设确定出风向二下可支持的最大风速为：4m/s、风向三下可支持的最大风速为：2m/s。其中，所有风向下(即风向一至风向三)可支持的最大风速中的最小风速为2m/s，由此可以确定被测终端设备可支持的最大风速为2m/s。
第三种：将所有风向下对应的最小的风噪过载点对应的风速确定为被测终端设备采集环境声时可支持的最大风速。
其中，在本公开的一个实施例之中，该风噪过载点可以理解为出现失真的最大风速，每一风向下会对应一个风噪过载点。基于此，本公开中将所有风向下的最小风噪过载点对应的风速确定为被测终端设备采集环境声时可支持的最大风速。
示例的，假设测量设备计算得到的，风向一下是在风速3m/s时出现风噪过载点，且风向一对应的风噪过载点为：第一值；风向二下是在风速5m/s时出现风噪过载点，且风向二对应的风噪过载点为：第二值；风向三下是在风速4m/s时出现风噪过载点，且风向三对应的风噪过载点为：第三值。其中，第一值小于第三值小于第二值，则可以确定，风向一对应的风噪过载点为所有风向下对应的最小的风噪过载点，此时，可以将风向一对应的风噪过载点所对应的风速确定为被测终端设备采集环境声时可支持的最大风速，即：被测终端设备采集环境声时可支持的最大风速为3m/s。
以及，在本公开的一个实施例之中，上述的被测终端设备采集环境声时可支持的最大风速意为：当被测终端设备在风速小于或等于该可支持的最大风速下采集环境声时，可以保证不会出现失真的情况。基于此，基于该可支持的最大风速即可确定出该被测终端设备正常工作所适用的风速和风向场景。

1501b、基于开启不同抗噪模式时对应的测量结果与未开启抗噪模式时对应的测量结果，确定各个抗噪模式的抗噪效果。
具体的，在本公开的一个实施例之中，可以利用开启不同抗噪模式时对应的测量结果减去相同条件下未开启抗噪模式时对应的测量结果，以此来确定不同抗噪模式的抗噪效果。其中，减去得到的差值的大小可以用来评估各个抗噪模式的抗噪效果。
示例的，假设在风速3m/s、风向一时，开启了硬件式的抗噪模式时计算所得的SNR的测量结果为：SNR A，在风速3m/s、风向一时，未开启抗噪模式时计算所得的SNR的测量结果为：SNR B，则利用SNR A减去SNR B得到SNR，即：SNR＝SNR A-SNR B，此时可以利用相减得到的SNR来评估硬件式的抗噪模式的抗噪效果，其中，若相减得到的SNR为正数，则若相减得到的SNR越大，说明硬件式的抗噪模式的抗噪改善越好，若相减得到的SNR为负数或0，则说明硬件式的抗噪模式的抗噪改善较差。
需要说明的是，上述仅针对“硬件式的抗噪模式”进行了相关举例介绍，其中，“软件式的抗噪模式”的计算方法原理类同，在此不再赘述。

以下对本公开的方法进行详细举例介绍。
特性解释。
风的等效声压：无外声场时，传声器由规定速度和方向的风引起的等效声压(以下简称风噪)。等效声压应为风的方向θ，频率f，风速v,的函数。由***的涡流和空气中的湍流造成。
测试环境要求：
测试环境：
测试环境应为自由场。
环境噪声：
测试环境的噪声不应对测试结果造成影响。1/3倍频程的等效持续声压应小于NR10曲线
风速：
测试环境内风速应为0m/s
房间尺寸：房间尺寸相对于风道和测试设备因足够大。不对测试的气流造成额外的影响
测试设备：
风发生器：
参考GB 12060.4-2012 IEC 60268-4的要求，风发生器应选用和自然风特性接近的设备，并且能在测试过程中稳定工作。
设备的噪声不应对测试结果造成影响，且在测试需求的风速下都可以稳定工作。
风道的尺寸相比被测设备的尺寸相比因足够大，足够完全覆盖被测设备附近产生的湍流，使测试环境和自然风环境尽量一致。如GB 12060.4-2012 IEC 60268-4中推荐的短装置用径流式风扇或长装置用轴向风扇。
使用的风发生器的具体参数须在测试报告中注明。
转台：
为保证测试的准确性和风发生器的设备体积，被测设备推荐安装在转台上，便于调整测试的风向。
也可根据实际情况，调整风发生器和被测设备的角度。
人工头
在测量时，设备因根据实际使用实况，安装在人工头对应的位置进行测试。用于模拟实际使用情况下的声学环境和风噪情况。
测试声源
人工嘴：
对于人声作为输入源的设备，用标准的人工嘴对应的测试位置代替人工嘴播放测试信号
测试扬声器：
不用人声作为输入源的设备，用标准的同轴测试音箱在对应的测试位置代替人工嘴播放测试信号。
被测设备：
本发明适用于包括但不限于以下设备或是模式：
头戴、免提、手持
为了模拟真实环境下设备的情况，设备须在模拟真实场景的情况下进行测试，包括人体的影响、外接部件、支架。被测设备的参考点应根据实际使用情况进行选择。
存在不同硬件设置(防风罩)和软件设置(降噪算法)的模式应各自分开进行测量，用于评估不同模式下的风噪。
本发明适用对于被测设备本身音频的测试；
也适用被测设备作为外接设备或是在通信***中进行测试；
测量方法
测试设置
根据实际适用场景，设备安装在人工头或是支架对应的位置，将终端设备、人工头和支架的整体视为被测设备。用于模拟真实情况下，人体或是其他物体对终端设备的影响。
测试信号响度
人工嘴应根据相关标准如[ITU-T P.340]在MRP处进行校准。均衡和响度的参数可参考[ITU-T P.581].
由于进行风噪相关的测试时，都是噪声环境。根据隆巴德效应(Lombard effect)，测试信号需要针对环境噪声进行补偿。
测试角度
根据实际使用情况，选择不同水平角和垂直角度的风向进行测试。
发送端
1)被测设备应安装在转台上，设备参考点在转台中心的垂直线上，风发生器主轴方向对准被测设备中心。风发生器和设备的水平夹角为
Figure PCTCN2022128763-appb-000002
垂直夹角为θ。
在不同水平角和垂直角度上重复2-5)
2)给被测设备上施加规定速度v的风，被测设备处的风速应该保持稳定。
3)记录稳定情况下被测设备采集到的纯噪声数据X，人工耳记录测试时的环境噪声。
4)根据环境噪声,人工嘴播放对应响度的测试信号，记录稳定情况下被测设备采集到的带噪信号数据Y

Figure PCTCN2022128763-appb-000003
垂直夹角为θ。
在不同水平角和垂直角度上重复2-5)
2)给被测设备上施加规定速度v的风，被测设备处的风速应该保持稳定。
3)记录稳定情况下人工耳记录到的噪声X
4)被测设备在对应模式下播放测试信号,人工耳记录带噪环境下测试信号为Y
5)关闭风发生器，根据噪声X，被测设备播放测试信号,人工耳记录安静环境下测试信号为Z
改变风速重复上述实验
注1：风噪声的本质为压力波动，应当小心避免设备因达到过载点损坏设备从而影响后续实验
测试结果：
测试结果应包含以下数据：
风噪的方向响应
风噪的方向响应是不同风向、不同风速下，被测设备输出信号。为设备的输出关于风的方向θ，风速v，频率f的函数。
用于评估设备在不同风向、不同风速下的风噪特性
风噪过载点：
风噪过载点应为不同方向上，设备能长时间正常工作(工作在线性区域)的最大风速。
信号中有信号发生削波或是达到峰值信号即可认为达到风噪过载点。
风噪失真率：
由于风噪在传声器中的信号有不稳定的特性，风噪引起的失真会间断出现，并且有风速越高失真出现越频繁的特点。
因此本发明提出通过计算信号中出现失真信号的比例，作为评价风噪失真程度的参数。
评价信号质量的相关参数：
信号质量的相关参数(如SNR、SDR、SAR、STOI、PESQ)应计算在不同风的方向θ，风速v下的参数。
通过不同场景下噪声X，安静环境下测试信号为Z，带噪环境下测试信号为Y，计算相关参数
对于多声道音频的应用：
对于输出多个声道的音频，应对输出的每一个声道进行计算。
在评估设备的风噪的方向响应和信号质量的相关参数时，本测试方法得到的多声道信号也可以根据相关方法转换成的单声道信号，便于评估相关参数。
测试结论：
测试应包含终端需要测试的不同模式，包括硬件设置(有无防风罩)，软件设置(相关降噪算法)。不同模式下的测试分开进行。
1)绝对参数
1、评价设备信号质量时，应选取对应风速下，所有方向上信号质量最低的参数作为结论。
2、评估设备可以支持的风速场景时，应选在所有角度、所有声道上都满足条件的最大风速作为结论。判定标准应参考相关标准根据设备的不同阶段、不同功能的实际情况制定。
3、评估设备采集环境声支持的风速时，选取所有角度、所有声道上风噪过载点的最小值作为结论，以保证设备在该风速下不会出现失真的情况。
2)评估改进效果
评估软硬件设置的效果时，在保证没有其他变量的情况下，通过打开相关设置测量得到的参数A减去关闭相关设置测量得到的相关参数B作为结论。
例如评估防风罩对SNR的提升效果时：
