Auditory fusion frequency (AFF) of impulse sound and paired pitch in 80 workers exposed to noise and 60 non exposed ones were measured to study the relationship between AFF and auditory fatigue.
为探讨闪声融合频率与听觉疲劳的关系,测量了80名接触噪声工人和60名非接触噪声人员的脉冲声和双音调闪声融合频率。
Theoretically, the expected output of impulse deconvolution is a spike, whose frequency spectrum can be considered as that of white noise.
从理论上说,脉冲反褶积的希望输出信号是一个尖脉冲,其频谱可以看成是一个白噪信号的频谱。
Conclusion Impulse noise causes more serious damage in causing high frequency hearing loss than continuous noise according to equal energy rule.
结论脉冲噪声所致高频听力损失的危害在能量相同的情况下大于稳态噪声。
The impulse motion and the unbalanced vibration of the pump generate certain structural noise which could be significantly expressed in frequency spectrum.
泵的脉动运动与不平衡振动产生了结构噪声,结构噪声在频谱中清晰显示出来。
