How many decibels is the noise standard

More than 55 decibels during the day is noise, and more than 45 decibels at night is noise.

pwd=1234 Extraction code: 1234 Lee Jong Suk will star in the new movie "Decibel", which is an action movie about the events that were prevented by the main figures such as the deputy captain, reporters, and the military security support command after a terrorist attack in the city center due to the submarine incident a year ago, and is expected to start filming this spring.

Legal analysis: a noise level of 30 to 40 dB is a relatively quiet normal environment; Anything above 50 decibels can affect sleep and rest. Due to insufficient rest, fatigue cannot be eliminated, and normal physiological functions will be affected to a certain extent; More than 70 decibels interfere with conversation, causing upset, lack of concentration, affecting work efficiency, and even accidents; Long-term work or living in a noise environment above 90 decibels can seriously affect hearing and lead to the occurrence of other diseases.

Legal basis: Law of the People's Republic of China on the Prevention and Control of Environmental Noise Pollution

Article 2 The term "environmental noise" as used in this Law refers to the sound generated in industrial production, construction, transportation and social life that interferes with the surrounding living environment.

"Environmental noise pollution" as used in this Law refers to the phenomenon that the environmental noise generated exceeds the environmental noise emission standards prescribed by the state and interferes with the normal life, work and study of others.

Article 3 This Law shall apply to the prevention and control of environmental noise pollution within the territory of the People's Republic of China.

This Law does not apply to the prevention and control of noise hazards caused by engaging in one's own production and business operations.

The noise standards are as follows:

A noise level of 30 to 40 dB is a relatively quiet normal environment; Anything above 50 decibels can affect sleep and rest. Due to insufficient rest, fatigue cannot be eliminated, and normal physiological functions will be affected to a certain extent; Above 70 decibels interfere with conversation, causing upset, lack of concentration, and affecting work efficiency.

Even accidents; Long-term work or living in a noise environment above 90 decibels can seriously affect hearing and lead to the occurrence of other diseases.

Summary. The specific decibel level of the noise standard will vary depending on the environment, national and regional regulations. Here are some common noise standards for reference:

Indoor noise standard: general residential area indoor: generally required noise not to exceed 35-40 decibels.

Quiet residential interior: generally required noise not to exceed 30 decibels. Outdoor Noise Standards:

Outdoor in general residential areas: the noise is generally required to be no more than 50-55 decibels. Commercial Area Outdoor:

Generally, the noise is required to be no more than 60 decibels. Outdoor in industrial areas: generally required noise not to exceed 70-75 decibels.

The specific decibel level of the noise standard will vary depending on the environment, national and regional regulations. Here are some common noise standards as a reference stool: Indoor Noise Standards:

Indoor in general residential areas: the noise is generally required to be no more than 35-40 decibels. Posture is quiet residential interior:

Generally, the noise is required to be no more than 30 decibels. Outdoor noise standard: Outdoor rough sales in general residential areas:

Generally, the noise is not more than 50-55 decibels. Outdoor in commercial areas: generally required noise not to exceed 60 decibels.

Outdoor in industrial areas: generally required noise not to exceed 70-75 decibels.

It is important to note that the above are just some of the common noise standard ranges, and the actual standards may vary depending on the region, use and specific situation. Specific noise standards should refer to local regulations and regulations. In addition, noise standards are usually measured in decibels, but different frequencies of noise have different perceptions and effects on people.

Therefore, in addition to the decibel level, factors such as the frequency characteristics and duration of the noise, as well as the impact on human health and the environment, should be taken into account when evaluating noise standards. When dealing with noise sources, please comply with local laws, regulations and regulations to minimise the impact of noise on the surrounding residents and the environment. If you encounter noise nuisance problems, you can complain to the relevant administrative department or environmental protection department and seek help.

Dear, you check Lu Hao, the noise standard is 80-100 points 1Indoor quiet environment: generally between 30-40 decibels; 2.

Ordinary residential area: generally between 50-60 decibels; 3.Urban road traffic funny noise:

Usually between 70-80 decibels; 4.Industrial production workshop: generally between 80-90 decibels; 5.

Public places such as airports and railway stations: usually between 90-100 decibels; 6.**Meeting, concert and other large-scale event site:

Usually above 100 decibels.

Noise standards refer to the limits of noise levels that are specified within a specific time and space. Depending on the country and region, the noise standards will also vary. Here are some common noise standard ranges and their corresponding noise situations:

1.Indoor noise standard: The indoor noise standard is generally 30-45 decibels, of which 45 decibels is the highest limit.

Below 30 dB is a very quiet environment, and 45 dB is a relatively quiet environment where ordinary speech can be heard. 2.Noise standards for urban residential areas:

Generally, it is 50-65 decibels, of which 65 dB is the highest limit. Below 50 dB is a relatively quiet environment, while 65 dB is a more noisy environment where you can hear the noise of cars and people. 3.

Noise standard in industrial areas: generally 70-85 decibels, of which 85 dB is the highest limit. Below 70 decibels, it is a relatively quiet environment, and 85 decibels is a noisy environment, where you can hear the sound of machines running and the shouts of people.

It is important to note that the scope of noise standards is based on different situations and environments, and needs to be assessed and managed on a case-by-case basis.
