关于暂时性听力损失(TTS)的规律问题,许多学者都进行过研究。但是他们大都是用白噪声或窄带噪声作声源。而像机车噪声这样复杂的声源所产生的TTS究竟如何,未见报道。为此,我们通过突验室模拟试验加以探讨,以便为制定机车司机室噪声卫生标准提供一定的依据。 On the law of temporary hearing loss (TTS), many scholars have conducted research. However, most of them use white noise or narrow-band noise as the sound source. However, it has not been reported how the TTS produced by a complicated source such as locomotive noise is. To this end, we through the laboratory simulation test to be discussed in order to develop a locomotive cab noise health standards to provide some basis.
