Factory high-decibel noise treatment method.
1. How many decibels is the noise standard?
According to the "Noise Standards for Urban Areas of the People's Republic of China", the maximum limits of environmental noise in five types of urban areas are clearly stipulated:
Daytime, nighttime, class 0 standards are suitable for areas that need special quiet, such as recuperation areas, high-end villa areas, and high-end hotel areas. Exceptions are made for nature reserves and living areas within Category 0 areas.
Daytime, nighttime, and Category 1 standards are applicable to areas dominated by residential, cultural and educational institutions. Daytime refers to 6:00 to 22:00 and night refers to 22:00 to 6:00.
Daytime, Night, Category 2 standards apply to industrial zones. Daytime refers to 6:00 to 22:00 and night refers to 22:00 to 6:00.
Daytime, nighttime, and Category 3 standards are applicable to areas on both sides of the traffic arteries. Daytime refers to 6:00 to 22:00 and night refers to 22:00 to 6:00.
Daytime, nighttime, and Category 4 standards are applicable to industrial, commercial, residential, medical and health areas. Daytime refers to 6:00 to 22:00 and night refers to 22:00 to 6:00.
2. Noise pollution standards.
3.Vibration damping control method: For machinery and equipment in the factory, vibration is one of the main sources of noise, so vibration damping control method can be used to reduce the noise pollution generated when the machine vibrates. Various vibration damping devices are usually used to reduce vibration treatment, such as reducing the vibration frequency of the machine or changing the vibration direction of the machine to reduce the impact of machine vibration on the surrounding environment.
