In June 2022, a new national law on noise pollution prevention and control was put into effect, addressing issues like disturbing nighttime construction noise, loud vehicle noises, excessive volume from entertainment and fitness systems and disturbances caused by pets. Since then, noise pollution prevention and control have been incorporated into government assessments.

Chongqing, a bustling metropolis in Southwest China with a population exceeding 32 million, is a national pilot city for noise pollution prevention and control. As such, it has been exploring the concept of quiet communities, establishing over 600 peaceful communities so far.

Chongqing Liangjiang New Area has worked to address the residents' noise-related issues. According to the local ecological environment bureau, the area has established 22 quiet communities, benefiting at least 200,000 people.

For instance, the Liheyuan community, which used to be plagued by noise pollution, has achieved Class 1 soundscape functional area standards through a series of initiatives. These include deploying a smart supervision cloud platform for 24-hour noise monitoring, renovating noise reduction facilities, enhancing amenities, replacing water grates and creating leisure spaces.

Data shows that in 2024, noise complaints in Chongqing Liangjiang New Area decreased by 36.4 percent compared to the previous year.

To improve noise pollution prevention and control, the area has strengthened the municipality's measures and introduced its own plan. The effort aims to simplify regulations for noise control and systematically address noise from industries, construction, transportation and social activities.
