Industry background
According to the "Guangzhou Park Acoustic Environment Function Division", all kinds of acoustic environment functional areas in parks implement the environmental noise limits stipulated in the national "Acoustic Environment Quality Standard" (GB3096-2008). All kinds of noise sources in and around the park shall implement the noise emission standards of the corresponding noise types. The limit of daytime ambient noise in category 1 area is 55dB (A), and the limit of nighttime ambient noise is 45dB (A). The limit of daytime ambient noise in category 2 area is 60dB (A), and the limit of nighttime ambient noise is 50dB (A). According to Guangzhou Park Sound Environment Function Zoning, the daytime is the period between 6:00 and 22:00, where the daytime environmental noise limit; night refers to the period between 22:00 and 6:00 on the next day, where the nighttime environmental noise limit is implemented. For the nighttime sudden noise of various acoustic environmental functional areas, the maximum noise level exceeding the environmental noise limit shall not be higher than 15dB (A).
It is understood that the Guangzhou Park Sound Environment Function Zoning will come into effect on January 1,2024, and the Notice of Guangzhou Environmental Protection Bureau on Printing and Issuing the Guangzhou Park Sound Environment Function Zoning (the First Batch) (No.157,2016) will be abolished at the same time. According to the requirements of the park, the park administrative authority shall, according to the park planning and the zoning, combine the main environmental noise limits of the park and the needs of visitors, delimit the quiet rest, fitness and entertainment areas in the park, and strengthen the acoustic environment management of the park.
project context
Recently Guangzhou baiyun mountain park noise online monitoring system open noise monitoring implementation, through noise real-time monitoring system monitoring park noise real-time data, match the acoustic and visual alarm, exceed the scene propaganda remind, smiling face noise monitor, real-time display the current noise value, overweight face expression color warning, have abnormal situation timely return software platform and alarm remind staff, timely processing to reduce nearby residents.
The equipment by the core components of professional sound level meter, data display, industrial data acquisition, etc, form a complete set of professional statistical analysis software platform, the monitoring data accurate, good stability, high integration, IP65 protection level, convenient installation, network access regulatory platform, comprehensive meet the demand of the use of the park scenic area!
