There is no noise subsidy, but the unit can be ordered to make corrections through complaints.
Article 5 of the National "Noise Hygiene Standards for Industrial Enterprises" stipulates: The general layout of the enterprise, on the premise of meeting the needs of the main project, should separate high-noise workshops from low-noise workshops. The working noise of enterprises should not exceed 85 decibels. The noise hygiene standard for industrial enterprises stipulates that the standard is 85dB. According to the principle of equal energy, if the contact time is reduced by half, the standard is allowed to be relaxed by 3dB.
Extended information
(1) Reduce the intensity of the sound source, replace high-noise processes and equipment with silent or low-noise processes and equipment, and improve the processing accuracy and installation technology of the equipment. , turning the sound-emitting body into a silent body, etc. This is the fundamental way to control noise.
For example, choose low-noise fans, motors, compressors, refrigerators, textile machines, pumps, etc. Silent steel plates are silent when struck. If mechanical equipment parts are made of silent steel plates, the intensity of the sound source will be greatly reduced.
(2) Separate high-noise equipment from low-noise equipment in a reasonable layout; separate operating rooms, rest rooms, and offices from noisy production environments; separate living areas from factory areas so that noise can flow with them. Natural attenuation as distance increases. Urban greening also plays a certain role in controlling noise. A 40m wide forest can reduce noise by 10 to 15dB.
However, in many cases, it is often impossible to control noise directly from the sound source due to technical or economic reasons. Therefore, it is also necessary to adopt technical measures such as sound absorption, sound insulation, noise elimination, and vibration isolation.
