Overall Situation of Environmental Noise in China
Urban spaces are well defined and categorized into five general zones with different requirements of environmental noises.
The Zone 0 of sanatoriums and villas, where people resided there to recover from illnesses, has the strictest noise requirement of less than 50dB by day and 40dB at night, followed by neighborhoods of hospitals, schools and residence areas, or the Zone 1, requiring the noise decibels to be lower than 55 by day and 45 at night.
Zone 2 is the mixed areas of commercial buildings and residential community, 60dB by day and 50 by night. After that, the other zones would be clear of residential community, with only industrial and transport areas included.
They use the map To divide the noise environment into day and night, the reported compliance rate of different areas reveal a stark contrast that worth our attention.
Especially, the sounds to represented every city.
