1. More reasonable urban planning
From the perspective of reducing noise, urban planning should consider the effective isolation of residential and industrial land, entertainment areas and heavy traffic areas. For example, in some foreign cities, environmental assessment departments will announce land planning in the future in advance.
As a result, a more reasonable urban layout can be achieved. my country's big cities are crowded with people and expensive land, so it is difficult to make such a plan, but what is certain is that this should and must be the direction of our efforts.
2. Build soundproof walls
Building soundproof screens or soundproof walls in areas with high traffic noise is also one of the methods. Take Beijing South Railway Station as an example. There is a soundproof screen with a total length of more than 400 meters and a height of 3.5 meters built next to the railway. It can effectively shield the railway noise and the noise of the flow of people at South Station to reduce the impact of noise on residents in nearby communities.
3. Stricter building codes
In the "Residential Building Code", there are clear regulations on the thickness of good sound insulation walls. However, in order to expand the area of ????the apartment, some developers now The thickness of the wall has been reduced, so that the thin wall cannot block various sounds from outside, upstairs, downstairs, and next door neighbors. Li Xiaodong said that this requires the state to further tighten residential construction standards and ensure their implementation.
4. Quieter product design
Technological improvements can play a certain role in noise reduction. Taking the speakers commonly used for square dancing as an example, if materials and designs that are more homogeneous are used, the propagation of the external sound in all directions can be controlled to a certain extent, thereby reducing the noise.
5. Better noise management
The noise of street food stalls, singing and dancing in entertainment venues, etc. can all be alleviated through strict management. Once disturbing noise occurs, residents can report and complain in accordance with the law, and they will be fined and closed to stop some sources of noise. For example, in 2005, the United Kingdom published the "London Road Traffic Noise Map", the world's largest official noise map at the time.
As long as people log in to the noise map website and enter their zip code, they can know the level of noise on the relevant streets, which will help the public understand the acoustic environment and participate in supervision. People should consciously stay away from noise. When the external environment cannot be changed, in addition to closing the windows, they can also consider wearing protective earplugs to reduce harm.
Avoid using noise to fight noise, such as wearing headphones to listen to music at high volume. Wearing headphones for a long time can cause hearing damage. In daily use, the volume should not exceed 60 decibels and the duration should not exceed 60 minutes.
