Description

音频信号调节方法及系统 技术领域
本发明涉及音频信号处理技术领域,尤其涉及一种音频信号调节方法及系统。
背景技术
人耳极具易损性,造成人耳损伤的因素包括病毒、环境噪声、耳毒性药物、遗传等,这些因素能够导致人耳不同程度和状态的听力损伤,严重的可能导致听力残疾。各种耳机和喇叭输出的声音都是线性输出,而人耳听觉功能对接收的声音进行的是非线性调控,由于耳机和喇叭输出的声音与听觉功能不匹配导致听觉“声损伤”,严重者导致听力障碍或者听力残疾。在现实生活中,听力损伤不易觉察,当觉察时可能问题已变得严重或不可逆转了,需要借助助听器或电子耳蜗的帮助,这将增加家庭和社会的负担。
世界卫生组织发布的消息称:目前全球有11亿青少年因为使用耳机可能导致听力损伤。强声会导致耳聋、耳鸣,但是有研究表明:低强度的声音的长时间刺激以及长期累积刺激同样会导致耳聋、耳鸣。在现实生活中,噪声是无处不在的。数据显示,新生儿听力损伤发生率0.1-0.3%,后天发展到10%左右,50%的60岁人口中有不同程度的听损,在这个听损发生、发展过程中,各种环境声音对听损的贡献率达到25%(各种环境声成为导致听力损伤或加重听力损伤的叠加因素),即听损与不科学的接受声刺激或不科学使用听觉直接相关。
声音是动态变化的,尤其是音乐和自然界的声音,具有较大的声压动态范围,其最小声压级和最大声压级相差可超过30dBspl。对于一些耳科疾病患者,由于其感受声音的内耳神经元对外界传入的各频率的声音的响应阈值不同。例如,高频听力损伤的人群,其对高频声音的响应阈值更高,需要更大的音量才能听到。因此高频听力损伤的人群使用普通耳机听音乐 时需要把输入人耳的音乐的整体音量调高才能听到音乐中高频部分的声音,而这种整体音量增长也将增强低频声音的能量。这对于高频听力损伤的人群中低频听力没有损伤人来说将会造成感受低频声音的内耳神经元的损伤,长久下来产生听损或耳鸣。目前聆听音乐或接听电话等外界音源通常使用耳机,耳机接受播放装置输入的音频信号把声音通过音量控制后输入到人耳,而耳机输出的声音对人耳听阈范围的各频率的声音的音量调节是一致的(各频率的声音同时放大或降低音量,是一种线性变化),并非按照使用者的实际听力状态进行调节输出。
发明内容

本发明实施例的有益效果在于:通过获取并分析用户的听力测试数据确定了用户对不同频率音频成分的听力特性,从而进一步确定了用于将音频信号调整为适于用户的实际听力的音频信号调节模型。并根据确定音频信号调节模型对用户所收听的音频信号进行调节,从而使得用户能够获取到适合于自身听力状况的音频,避免收听与自身听力状况不匹配的音频对听力造成的损伤。

S20、根据获取的所述听力测试数据确定所述用户在不同频率点的听力参数值,生成适于所述用户的音频信号调节模型;
S30、根据所述音频信号调节模型对接收的音频信号中对应于各频率点的音频数据进行音频调节以输出至所述用户的人耳进行聆听。
本实施例中通过获取并分析用户的听力测试数据确定了用户对不同频率音频成分的听力特性,从而进一步确定了用于将音频信号调整为适于用户的实际听力的音频信号调节模型。并根据确定音频信号调节模型对用户所收听的音频信号进行调节,从而使得用户能够获取到适合于自身听力状况的音频,避免收听与自身听力状况不匹配的音频对听力造成的损伤。
在一些实施例中,步骤S10中的用户的听力测试数据由听力测试设备对用户进行听力测试得到,可以是取自用户的历史听力测试数据,也可以是实时测得的用户的听力测试数据,本发明实施例对此不作限定。听力测试设备可以采用精细化听力测试设备。
在一些实施例中,的步骤S20中的听力测试数据包括每个倍频程内的多个测试频率点的听力参数阈值,所述听力参数阈值至少包括由听力测试设备对用户进行测试得到的轻柔阈值(即,第一阈值)、最适阈值(即,第二阈值)和不适阈值(即,第三阈值)。
人耳听音的频率范围为20Hz到20KHz,声音信号频谱分析一般不需要对每个频率成分进行具体分析。为了方便起见,把20Hz到20KHz的声频范围分为几个段落,每个频带称为一个频程。频程的划分采用恒定带宽比,即保持频带的上、下限之比为一常数。实验证明,当声音的声压级不变而频率提高一倍时,听起来音调也提高一倍。若使每一频带的上限频率比下限频率高一倍,即频率之比为2,这样划分的每一个频程称1倍频程,简称倍频程。
如图2所示,在一些实施例中,所述根据获取的所述听力测试数据 确定所述用户在不同频率点的听力参数值,以生成适于所述用户的音频数据调节模型包括:
S21、根据各频率点的轻柔阈值,确定对应于各频率点的声压级;即,以各频率点的轻柔阈值作为引起用户对频率值为各频率点的音频成分响应的声压级;
S22、以各频率点的所述不适阈值与所述最适阈值的差值作为对应于各频率点的波峰压缩比;即,以所述不适阈值与所述最适阈值的差值作为频率值为各频率点的音频成分的波峰压缩比;
S23、以各频率点的所述最适阈值与所述轻柔阈值的差值作为对应于各频率点的波谷压缩比;即,以所述最适阈值与所述轻柔阈值的差值作为频率值为各频率点的音频成分的波谷压缩比;
S24、至少基于所述声压级、波峰压缩比、波谷压缩比,生成适于所述用户的音频数据调节模型。
本实施例中的步骤S21中,通过将轻柔阈值作为引起用户对频率值为所述某一测试频率点的音频成分响应的声压级保证了经本实施例的音频信号调节模型调节后的音频信号肯定能够被用户所听到,保证了用户能够完整的听到音频信号中所包含的所有频率成分,从而在确保不因声压级过高而对人耳造成损伤的情况下还确保了用户能够清晰的听到所有的频率成分。
本实施例中的步骤S22、S23中,通过确定频率值为测试频率点的音频成分的波峰压缩比和波谷压缩比的方式确定了对该音频成分调节的上下限,保证了经调整后输出的音频信号所包含的所有的频率成分都在适于用户实际听力状况的范围内波动,从而避免了周期性出现超出大声阈值和/或轻柔阈值之外的频率成分而对人造成不适感甚至对人耳造成损伤。
如图3所示,在一些实施例中,所述根据所述音频信号调节模型对接收的音频信号中中对应于各频率点的音频数据进行音频调节,以输出至所述用户的人耳进行聆听包括:
S31、确定接收的音频信号中对应于各频率点的音频数据;
S32、根据所述音频调节模型对所述应于各频率点的音频数据;
S33、将根据所述音频调节模型调节后的音频信号输出至所述用户的人耳进行聆听。
在本实施例中音频信号处理设备在接收到外部输入的音频信号之后,首先执行步骤S31以确定音频信号所包含的所有的音频成分(即,频率成分),然后执行步骤S32根据确定的音频信号调节模型来条接接收的音频信号所包含的所有的音频成分以适于用户的实际听力状况,之后执行步骤S33将调节后的音频信号发送至用户的人耳进行聆听。步骤S33中发送至人耳的方式可以是通过与音频信号处理设备连接的耳机进行传输。
在一些实施例中,所述听力测试数据包括每个倍频程内的多个测试频率点的在多个不同时期的听力阈值。
如图4所示,在一些实施例中音频信号调节方法还包括:
S41、对每一个频率点的多个听力阈值按照时间由远到近的顺序进行排序;
S42、比较对应于每一个频率点的排序后的多个听力阈值之间的大小;
S43、当比较结果表明某频率点的多个听力阈值按照时间由远到近的顺序趋于增大时,生成听力损伤告警信号以通知所述用户在所述某频率点的听力发生了下降。
本实施例中根据针对于用户的不同时期的听力测试数据的变化趋势能够发现用户的听力下降是否发生下降,并在发现用户的听力下降时能够及时的向用户发出告警信息,以便用户能够及时就医或者作出适当调整,以避免听力进一步的恶化。
在一些实施例中,所述听力参数阈值还包括不适阈值;所述根据获取的所述听力测试数据确定所述用户在不同频率点的听力参数值,以生成适于所述用户的音频数据调节模型还包括:
以各频点的不适阈值作为频率值为各频率点的音频成分的瞬时电压最大阈值。
本实施例中通过设定音频信号的频率成分的输出瞬时电压最大阈值确保了按照音频数据调节模型调节后的音频数据中不存在瞬态脉冲达到不适阈值的情况,从而避免了瞬态脉冲对人耳造成的尖锐刺激引发的瞬时 耳鸣或者长久损伤。
以下以耳鸣频率为4490Hz的患者为例,其在同一倍频程的4490Hz和5040Hz的声刺激的基本数据如下表:
Hz HLdB SOFTdB MCLdB LOUDdB UCLdB
4490 35 43 48 54 70
5040 40 49 56 62 69
如上表所示分别获取了同一个倍频程内两个频率点4490Hz和5040Hz的五个听力参数阈值,分别包括:听力阈值HL(该患者人耳能够听到的最低声音)、soft阈值(感觉轻柔的阈值、小于MCL)、最适阈值MCL、loud阈值(感觉大声的阈值,小于UCL)、不适阈值UCL。人耳对同一频率点不同分贝的声音的敏感度是不同的,例如,对于频率为4490Hz的音频成分,当分贝数大于35dB时该患者才能够听到该频率的声音,当分贝数为43dB左右时该患者可以听到该频率轻柔的声音,当分贝数为48dB时该患者能够听到该频率最合适的声音,当分贝数为54dB时该患者会觉得该频率的声音较大,当分贝数为70dB或以上事该患者会觉得不舒服。上述听力参数阈值由听力测试设备测试得到,听力测试设备采用精细化听力测试设备,可以精准的测试用户对于某一频率点的听力参数阈值。
通过以下步骤确定音频调节模型:
A、饱和输出控制运算:以测试频点对应的不适阈值UCL作为音频信号瞬时最大电压输出限度。
B、控制输出声压算法:以测试频点对应的soft阈值作为标准,设定引起该频点响应的声压级。
C、非线性控制算法:以loud阈值与最适阈值MCL的差值设定波峰压缩比,以最适阈值MCL与soft阈值的差值设定波谷压缩比,控制输出声压动态范围。
在经上述步骤处理时还可以对音频信号进行调频调幅,具体地:在进行上述运算处理时,可设置输出声音整体变化特征,可对经A-C运算的声音进行调频调幅设置以满足不同耳科患者的需要,例如:
a、对于一些耳科疾病患者(例如,耳鸣患者),可以选择频宽,对选定频宽范围内的声音进行额外增加和削减输出控制,包括增加输出声压 级分贝数值或降低分贝数值,步进不小于1dB。
b、可设置调频频率,调节音频信号的振幅按调频频率周期变化,调频频率可选不低于6Hz。
c、调幅:音频信号的振幅可以在不小于±1dB的数值选择振幅变化强度,按预期损伤特性进行设置。
此外,还可以进行连续播放时程衰减控制:时程设置可选择10m\20m\30m,当连续播放时间超过设定的时程时,自动控制音量衰减1-10dB,用降低音量的方式提示用户停止播放,以避免长时间不间断的播放对人耳造成损伤。
最后,通过音频信号调节设备的输入端D和输出端A,进行D/A转换校准,使音频电信号电压值与喇叭输出声压值一致。
本发明的装置和方法,只需获得听力测试设备所测得的用户的听力测试数据,便可使用本发明的方法为用户定制音频信号,可安装在任何音频播放装置(用于向音频调节设备输入音频信号),一端与播放装置连接,一端与各种扬声器或耳机相(用于播放经音频调节设备调节后的音频)连接,使得输出声音符合人耳听觉功能的不同状态。起到科学用耳、保护听觉功能、优化听觉、避免不良声刺激造成的听力损伤以及避免或减少耳鸣的发生与控制耳鸣响度增长。
