What is the noise standard?

According to China's "Community Noise Emission Standard", the noise standard in residential areas is between 45 decibels and 55 decibels, which is equivalent to the volume at which two people can hear each other clearly when talking in a room. If it exceeds this volume, it can be regarded as noise disturbing the people.

The noise level is 30 ~ 40 decibels, which belongs to a quiet normal environment. If it exceeds 50 decibels, it will affect sleep and rest. Due to lack of rest, fatigue cannot be eliminated, and normal physiological functions will be affected to some extent.

Foreign methods to deal with noise

In 2004, London's noise law even stipulated that residents should not use radio or TV more than 8 meters, domestic pets should not make too much noise, and no one should honk, whistle or whistle in residential areas. In London's subway, the noise of the train is also very loud, but because passengers seldom talk, most of them read books and newspapers silently, so they don't feel upset.

Compared with the British, the Swiss are more cautious. The state stipulates that when renting an apartment, no bathing is allowed after 10 at night; After 3 o'clock in the morning, men must sit and urinate to avoid making noise and disturbing neighbors' sleep.

In addition, Germany stipulates that after 10 at night, no loud noises, no music and no parties are allowed. If you want to have a party at the weekend, you must ask your neighbors for permission in advance.

New york, USA, even stipulates that domestic dogs can only bark for 5 minutes at night and 10 minutes during the day, otherwise they will be fined.
