防止和隔离生产噪声是在有强烈噪声的厂房或试验室设计中的重要问题。强烈的噪声会影响人们的健康,影响生产的顺利进行。重型机械试验室中在开动机器时的振动很大,所发出的噪声也相当强烈,噪声级最高可达到135分贝,最低的也有110分贝。在这样强烈的噪声环境里,工作人员无法正常地工作,必须采取措施,消除和减弱噪声的影响。 随着近代科学技术的发展,抑止噪声的方法也日趋增多。有的是直接消除噪声产生的原因或在声源中减弱噪声。例如改进机械设备的设计及安装以减少振动,或在机械中
Preventing and isolating production noise is an important issue in the design of a strong noise factory or laboratory. Strong noise can affect people’s health and affect the smooth progress of production. In the heavy machinery laboratory, the vibration during the operation of the machine is very large, and the noise emitted is also quite strong. The noise level can reach up to 135 decibels, and the lowest is 110 decibels. In such a strong noisy environment, workers cannot work properly and measures must be taken to eliminate and reduce the impact of noise. With the development of modern science and technology, the methods of suppressing noise are also increasing. Some directly eliminate the cause of noise or reduce the noise in the sound source. For example, improving the design and installation of mechanical equipment to reduce vibration, or in machinery
