In 1992, noise levels in the city of Chongqing caused significant inconvenience and significant social cost. As part of a Franco-Chinese project in partnership with bilateral institutions, a plan to control and limit noise pollution has been implemented over a period of 3 years. This plan had to fulfill 4 objectives:
- Road traffic management: decision support tool
- Insulation of facades: first steps towards building regulations
- Land management: decision support tool
- Control of noise emissions from establishments open to the public and industries: institution of the polluter-pays principle.
With 40 years of experience in environmental acoustic engineering and in international consultancy on acoustic regulations, the acoustic firm Tisseyre + Associés makes its expertise available to public institutions. Thanks to our constant research and development, our recommendations on the regulations to be adopted are based on databases collecting tens of thousands of different sites (Urbanistic Noise Map®) that we analyze through 3D modeling methods. More than a working methodology, our 3D temporal sound maps of landscapes are real working aids promoting collaboration with different actors since they are dynamic and didactic.
Pilot operation in terms of acoustic regulations
As part of a college of project owners and contractors, we led various round tables to set up acoustic regulations for different types of buildings and in environmental matters. This work was used in particular to export French acoustic regulations to China, while adapting them to the specificities of Chongqing.
Environmental acoustic mission
As part of this project, we have soundproofed many establishments open to the public and having a significant impact on their sound environment, or conversely, highly exposed to transport noise. Thus we have soundproofed many markets, bars, nightclubs, industrial buildings and offices.
Local communication mission
In order to make the population aware of the problems of nuisances, we have set up noise displays in the main arteries of the city.
