噪声是人们日常生活中必然会接触到的声音,过度地暴露于噪声环境中会对人们的听力造成损害,特别是在工地、大型工厂、军事演练基地等场合,噪声的影响尤为巨大。人们通过戴耳罩、塞耳棉等方式在一定程度缓解噪声损害,但随之而来的不便及不舒适性会使工作人员降低对噪声危害的重视程度,从而忽略防护措施。但是对于工地、大型工厂和军事演练基地等场合是不安装噪声检测设备的,所以人们无法得知当前的噪声值,则无法根据噪声值做出对应的防护措施,则对人们的健康带来隐患。Noise is a sound that people will inevitably come into contact with in their daily lives.

参照图4,在一些实施例中,步骤S300包括但不限于包括步骤S310至S330,步骤S300包括:Referring to FIG. 4, in some embodiments, step S300 includes but is not limited to steps S310 to S330, and step S300 includes:
S310、将噪声信号进行傅里叶变换处理,得到噪声变换信号;S310. Perform Fourier transform processing on the noise signal to obtain a noise transformed signal;
S320、将噪声变换信号进行补偿处理,得到补偿信号;S320. Perform compensation processing on the noise transformation signal to obtain a compensation signal;
S330、将补偿信号和暴露时长进行平均处理,得到噪声暴露值。S330. Perform averaging processing on the compensation signal and the exposure time to obtain a noise exposure value.
由于输入的噪声引号为语音帧信号,所以需要将噪声信号进行傅里叶变换处理以得到噪声变化信号,以便于进行补偿处理。由于不同麦克风之间频响存在差异,因此通过测量麦克风的频响,对缺失部分进行补偿,以通过麦克风模 仿人耳对声音的接收情况,从而计算出人耳的实际噪声暴露情况。因此,将噪声变换信号进行补偿处理得到补偿信号,通过补偿得到有效的补偿信号,然后根据补偿信号和暴露时长进行平均处理得到噪声暴露值,以得到每一个在线设备的噪声暴露值。Since the input noise quotes are speech frame signals, it is necessary to perform Fourier transform processing on the noise signal to obtain a noise change signal for compensation processing. Due to the difference in frequency response between different microphones, the missing part is compensated by measuring the frequency response of the microphone to simulate the human ear's reception of sound through the microphone, so as to calculate the actual noise exposure of the human ear. Therefore, the noise transformation signal is compensated to obtain a compensation signal, and an effective compensation signal is obtained through compensation, and then the noise exposure value is obtained by averaging the compensation signal and the exposure time to obtain the noise exposure value of each online device.
具体地,由于麦克风不同,录音过程中各频点的敏感度不一致,而我们期望麦克风采集的噪声信号对应的频响曲线是一条直线,但是麦克风所采集的噪声信号如图5和图6所示,在图5和图6中,横坐标均表示单位为Hz的频点,图5的纵坐标表示单位为分贝的敏感度,图6的纵坐标表示单位为分贝且以1000Hz、0dB为参考基准的噪声强度,并且麦克风采集的噪声信号实际为一条曲线,因此需要对噪声信号处理得到的噪声变换信号进行补偿处理。其中,对噪声变换信号进行补偿处理需要确定噪声变换信号对应的频点,且确定每个频点对应的补偿值,然后构建补偿值序列,以根据补偿值序列对噪声变换信号进行补偿处理。若假设噪声变换信号在各频点的补偿值序列为H,则补偿值序列H可以表示为:Specifically, due to different microphones, the sensitivity of each frequency point during the recording process is inconsistent, and we expect the frequency response curve corresponding to the noise signal collected by the microphone to be a straight line, but the noise signal collected by the microphone is shown in Figure 5 and Figure 6 , in Figure 5 and Figure 6, the abscissa indicates the frequency point in Hz, the ordinate in Figure 5 indicates the sensitivity in decibels, and the ordinate in Figure 6 indicates that the unit is decibel and takes 1000Hz and 0dB as the reference noise intensity, and the noise signal collected by the microphone is actually a curve, so it is necessary to perform compensation processing on the noise transformation signal obtained from the noise signal processing. Among them, performing compensation processing on the noise-transformed signal requires determining the frequency points corresponding to the noise-transformed signal, and determining the compensation value corresponding to each frequency point, and then constructing a compensation value sequence to perform compensation processing on the noise-transformed signal according to the compensation value sequence. If it is assumed that the compensation value sequence of the noise transformed signal at each frequency point is H, then the compensation value sequence H can be expressed as:
H
1=[x
1,x
2,x
3,…,x
N] (1)
H 1 =[x 1 , x 2 , x 3 , . . . , x N ] (1)
其中,N表示频点数;设置采样率为F;n为一个变量,表示第n个频点,n的取值区间为1至N;x
n表示第n个频点的补偿值,x
n对应的频点为f
n;频点与采样率之间的对应关系为:
Among them, N represents the number of frequency points; set the sampling rate to F; n is a variable, representing the nth frequency point, and the value range of n is 1 to N; x n represents the compensation value of the nth frequency point, and x n corresponds to The frequency point of is f n ; the corresponding relationship between the frequency point and the sampling rate is:
若麦克风上设有防护设备,其中,防护设备包括:麦克风罩,麦克风塞,则防护设备对麦克风采集噪声信号存在影响。因此防护设备对采集的噪声信号在各频点具有阻挡能力。假设噪声信号对应的噪声能量为A的情况下测量得到带上防护设备各个频点的能量为P,定义H
2为麦克风统计噪声时保护设备的 修正参数,则有:
If a protective device is provided on the microphone, wherein the protective device includes: a microphone cover and a microphone plug, the protective device will affect the noise signal collected by the microphone. Therefore, the protective equipment has the ability to block the collected noise signals at each frequency point. Assuming that the noise energy corresponding to the noise signal is A, the measured energy of each frequency point of the protective equipment is P, and H2 is defined as the correction parameter of the protective equipment when the microphone counts the noise, then:
H
2=A-P=[y
1,y
2,y
3,…,y
N] (3)
H 2 =AP=[y 1 ,y 2 ,y 3 ,...,y N ] (3)
其中,y
N表示第n个频点的修正值,n的取值区间为1至N;因此,对于携带防护设备的麦克风时,根据修正参数对噪声变换信号进行修改以得到修正信号,以根据修改信号计算得到的噪声暴露指数更加准确。
Among them, y N represents the correction value of the nth frequency point, and the value range of n is from 1 to N; therefore, for the microphone carrying protective equipment, the noise transformation signal is modified according to the correction parameters to obtain the correction signal, so as to obtain the correction signal according to The noise exposure index calculated by modifying the signal is more accurate.
其中,假设噪声信号为s,将噪声信号进行傅里叶变换处理主要是通过傅里叶变换公式对噪声信号进行傅里叶变换处理,且对噪声信号进行傅里叶变换处理如下:Among them, assuming that the noise signal is s, performing Fourier transform processing on the noise signal is mainly to perform Fourier transform processing on the noise signal through the Fourier transform formula, and perform Fourier transform processing on the noise signal as follows:
S=FFT(s) (4)S=FFT(s) (4)
对噪声信号进行傅里叶变换处理得到噪声变换信号后,对噪声变换信号以得到补偿信号,且对噪声变换信号进行补偿处理如下:After performing Fourier transform processing on the noise signal to obtain the noise transformation signal, the noise transformation signal is obtained to obtain the compensation signal, and the compensation processing of the noise transformation signal is as follows:
S=S+H
1-H
2+A(5)
S=S+H 1 -H 2 +A (5)
得到噪声变换信号后,对噪声变换信号进行反向变换得到有效的补偿信号如下:After the noise transformation signal is obtained, the noise transformation signal is inversely transformed to obtain an effective compensation signal as follows:
s=IFFT(S) (6)s=IFFT(S) (6)
因此,通过公式(4)至(6)对噪声信号进行傅里叶变换处理后再进行补偿处理,以得到更加准确的噪声信号。Therefore, the noise signal is subjected to Fourier transform processing through formulas (4) to (6) and then compensated to obtain a more accurate noise signal.
在一些实施例中,步骤S330包括但不限于包括步骤S331,步骤S330包括:In some embodiments, step S330 includes but is not limited to include step S331, and step S330 includes:
S331、将补偿信号和暴露时长以预设的计算公式进行平均处理,得到噪声暴露值。S331. Perform averaging processing on the compensation signal and the exposure time using a preset calculation formula to obtain a noise exposure value.
通过以预设计算公式对补偿信号和暴露时长进行平均处理,能够准确得到噪声暴露值,也即知晓在整个暴露时长中平均的噪声幅度,更加准确地显示出用户所处环境的噪声影响程度。By averaging the compensation signal and the exposure time with a preset calculation formula, the noise exposure value can be accurately obtained, that is, the average noise amplitude in the entire exposure time can be known, and the noise impact degree of the user's environment can be more accurately displayed.
具体地,根据预设的计算公式对补偿信号和暴露时长进行平均处理得到噪声暴露值,如下:Specifically, the noise exposure value is obtained by averaging the compensation signal and the exposure time according to the preset calculation formula, as follows:
式中,p
ref表示1000Hz处人耳可听的最小声压幅值20μPa。
In the formula, pre ref represents the minimum sound pressure amplitude audible to the human ear at 1000Hz, 20μPa.
因此,通过公式(7)和(8)对补偿信号和暴露时长进行平均处理得到噪声暴露值,以更加准确地表示用户所处环境的噪声影响程度。Therefore, the noise exposure value is obtained by averaging the compensation signal and the exposure time through formulas (7) and (8), so as to more accurately represent the noise influence degree of the user's environment.

其中,表1为根据预设第二时间间隔周期更新的噪声暴露指数。参照表1,其中预设的第一时间间隔和第二时间间隔为t,因此间隔t时更新在线设备的设备数量,并定时更新噪声暴露指数。如表1所示,若已注册设备包括设备1、设备2、设备3,在t1时间检测到在线设备只有设备3,则计算得到设备3的噪声暴露值为c1,则噪声暴露指数为c1;若在t6时间,检测到在线设备包括设备1和设备3,且设备1的噪声暴露值为a1,而设备3的噪声暴露值为c6,则噪声暴露指数为(a1+c6)/2;若在t8时间,在线设备包括设备1、设备2和设备3,且设备1的噪声暴露值为a3,设备2的噪声暴露值为b1,设备3的噪声暴露值为c8,则当前的噪声暴露指数为(a1+b1+c8)/3。因此,根据在线设备的噪声暴露值和设备数量计算得到噪声暴露指数,则得到的噪声暴露指数更加具体化,且用户可以更加准确的掌握自己的噪声暴露情况。Among them, Table 1 is the noise exposure index updated according to the preset second time interval cycle. Referring to Table 1, the preset first time interval and second time interval are t, so the number of online devices is updated at an interval of t, and the noise exposure index is regularly updated. As shown in Table 1, if the registered devices include device 1, device 2, and device 3, and only device 3 is detected as an online device at time t1, then the calculated noise exposure value of device 3 is c1, and the noise exposure index is c1; If at time t6, it is detected that the online devices include device 1 and device 3, and the noise exposure value of device 1 is a1, and the noise exposure value of device 3 is c6, then the noise exposure index is (a1+c6)/2; if At time t8, the online devices include device 1, device 2 and device 3, and the noise exposure value of device 1 is a3, the noise exposure value of device 2 is b1, and the noise exposure value of device 3 is c8, then the current noise exposure index It is (a1+b1+c8)/3. Therefore, if the noise exposure index is calculated based on the noise exposure value of online equipment and the number of equipment, the noise exposure index obtained will be more specific, and users can more accurately grasp their own noise exposure.
