目的：为了解坑道噪声污染的程度，为噪声防制提供科学依据。方法：选择某阵地坑道，采用ＨＳ５６１８型积分声级计，按等效声级法监测机房声源噪声与环境噪声。结果：坑道环境噪声本底值３３．６～３９．０ｄＢ（Ａ）。当设备运行时，各机房声源噪声值超标率为１１．２％，其中大于８５ｄＢ（Ａ）的测点占２２．３％；坑道环境噪声值均小于８５ｄＢ（Ａ）。结论：坑道机房声源噪声均超标。为了防止坑道噪声污染，建议采取综合措施，降低机房声源噪声，以保护作业人员听觉器官免遭损害
Objective: To understand the extent of noise pollution in tunnels and provide a scientific basis for noise control. Methods: Select a certain tunnel, using HS5618 integral sound level meter, according to the equivalent sound level method to monitor the engine room sound source noise and environmental noise. Results: The tunnel background noise floor value is 33.6 ~ 39.0dB (A). When the equipment is running, the exceeding rate of sound source noise value of each computer room is 11.2%, among which, the measuring points of more than 85dB (A) account for 22.3%; and the environmental noise of tunnels is less than 85dB (A). Conclusion: The noise of tunnel engine room is excessive. In order to prevent tunnel noise pollution, it is recommended that comprehensive measures be taken to reduce the sound source noise of the engine room so as to protect the auditory organ of the operator from damage
