【摘要】：次声是频率范围在0.0001～20Hz的机械振动波，是生产噪声和公共噪声的重要组成部分。次声对机体的作用是广泛而复杂的，涉及组织、器官、细胞、分子等多层面。次声的生物学效应也是广泛而复杂的，可以影响中枢神经系统、内分泌系统、呼吸系统、心血管系统、消化系统、听觉系统、视觉系统、血液及生殖系统等。为了保护有关作业者及群众的健康，制订相应的次声卫生标准十分必要。目前在国际上尚无统一的次声卫生标准，一些国家初步提出的标准差异较大，，例如：俄罗斯规定容许水平为90dB；美国环境保护机构在“噪声的公众健康和福利标准”中提出，次声强度在130dB以下不会构成对公众的危害；日本环境厅提出的次声限值为不高于120dB；德国制订的现行限定标准为不高于95dB。我国尚未有相应的工业次声卫生标准。次声装置做为一种非致死性武器，在一些军事技术发达的国家已取得了技术性突破，法、俄、英、德等国均已研制成了不同类型的非致死性次声武器，用于抗暴、保安、局部战争等。
[Abstract]:Infrasound is a mechanical vibration wave with frequency ranging from 0.0001 Hz to 20 Hz. It is an important part of noise production and public noise. Infrasound's effect on the body is extensive and complex, involving tissue, organs, cells, molecules and other levels. The biological effects of infrasound are also extensive and complex, which can affect the central nervous system, endocrine system, and the voice. Absorption system, cardiovascular system, digestive system, auditory system, visual system, blood and reproductive system.
In order to protect the health of workers and people concerned, it is necessary to establish corresponding hygienic standards for infrasound. There is no uniform hygienic standard for infrasound in the world at present. There are great differences in the standards proposed by some countries, for example, the allowable level of 90 dB stipulated by Russia, and the public health and welfare standard for noise issued by environmental protection agencies in the United States. It is proposed that infrasound intensity below 130 dB will not pose a hazard to the public; the limit value of infrasound proposed by Japan's Environmental Agency is not higher than 120 dB; and the current limit standard set by Germany is not higher than 95 dB. There is no corresponding hygienic standard for industrial infrasound in China.
As a non-lethal weapon, infrasound devices have made technical breakthroughs in some developed countries. France, Russia, Britain, Germany and other countries have developed different types of non-lethal infrasound weapons for anti-riot, security, local wars and so on.
