Indoor noise decibel standard.
Noise is often with us in our daily lives, especially those who live in cities. In order to ensure that people's normal life and work are not disturbed by noise, the state has formulated indoor noise decibel standards. Knowing these standards will help us determine if we are suffering from noise pollution and take action accordingly.
1. Indoor decibel standard for residential noise.
According to the "Acoustic Environment Quality Standards" issued by the State Environmental Protection Agency, the noise in residential areas shall not exceed 55 decibels during the day and 45 decibels at night. At the same time, the national mandatory standard "Code for Sound Insulation Design of Civil Buildings" also clearly stipulates that the noise standard of a class of residential buildings (places with sleeping and resting as the main purpose) shall not exceed 35 decibels during the day and 30 decibels at night. The noise standard for Class II residential buildings (buildings with residential and cultural and educational institutions as the main purpose of living) shall not exceed 45 decibels during the day and 40 decibels at night.
The development of these standards is based on scientific research and the accumulation of practical experience to ensure that people's normal life and work are not disturbed by noise. The difference in decibel standards between daytime and nighttime is due to the fact that people are mostly active during the day and have a relatively high tolerance for noiseAt night, people need to rest and have a relatively low tolerance for noise.
Second, the main indoor noise.
Indoor noise is mainly used in various equipment and activities inside the building, such as elevators, air conditioners, exhaust fans, household appliances, etc., as well as noise from the outside, such as adjacent roads, construction sites, etc. These noises not only affect people's rest and work, but can also have an impact on people's physical and mental health. For example, people who live in high-noise environments for a long time may experience problems such as hearing loss, insomnia, high blood pressure, etc.
3. How to reduce indoor noise.
There are a number of measures we can take to reduce indoor noise. First of all, you can choose materials with good sound insulation effect when decorating, such as soundproof glass, soundproof doors, etc.;Secondly, soundproofing equipment such as soundproof windows, soundproof panels, etc. can be usedIn addition, we can also reduce noise by changing our habits, such as avoiding noisy activities late at night.
Fourth, protect their own rights and interests.
If you find that the indoor noise in your home exceeds the standard, you can take some steps to protect your rights. First of all, you can report the problem to the property management company or neighborhood committee and ask for their help;If you can't solve the problem, you can file a complaint with the relevant department or seek legal help. At the same time, understanding the relevant laws, regulations and standards also helps us to better protect our rights and interests.
V. Conclusions. Indoor noise decibel standards are an important measure to ensure people's normal life and work. Understanding these standards and taking action accordingly can help reduce indoor noise and improve quality of life. At the same time, we should also pay attention to the environmental noise problem around us and take positive actions to protect our rights and interests.
