噪音,使人厌烦的嘈杂声音,亦指一切有干扰性的信号。可见,噪音之于人类,绝非天籁之音。它的存在不仅会影响到人的心理健康,时间长了,还会影响到身体健康。因而,对待各种各样的噪音,人们总是想方设法地来控制它们、降低它们、消除它们。比如,建筑工地为控制噪音,通常会采取限定工作时间、架设隔音网板等方法以防扰民；汽车为降低噪音,会采取改进传动装置、加装隔音材料等方法以“劝中求静”；而各国的政府部门为了让民众有个安静的生活环境,更是会祭出“法规”这个重器来严控噪音。像北京市政府近日就讨论并原则通过了新的《北京市环境噪声污染防治管理办法》,其中拟对夜间违规施工的单位和在禁鸣区内按喇叭的汽车驾驶者分别开出20万元和5000元的高额罚款……所有这些都是为了两个字——降噪。
Noisy, annoying noisy sounds, but also signals of any interference. Can be seen that noise in humans, not the sound of nature. Its existence will not only affect people’s mental health, a long time, but also affect their health. Thus, treating all kinds of noise, people are always trying to control them, lowering them and eliminating them. For example, in order to control noise, construction sites usually take limited working hours and noise barriers are installed to prevent people from disturbing. In order to reduce noise, automobiles will adopt the methods of improving transmission and installing sound insulation materials to “persuade them to seek rest” In order to let people have a quiet living environment, the government departments of various countries will pay more attention to noise control by using the heavy weight of “laws and regulations”. As Beijing Municipal Government recently discussed and approved in principle the new “Measures for the Administration of Environmental Noise Pollution Prevention and Control in Beijing”, in which it plans to set aside 200,000 yuan for units that violate construction at night and drivers who horn in the noisy area And a $ 5,000 fines ... all for two words - noise reduction.
