Abstract

The invention discloses an evaluation method for acoustic environment quality monitoring, which comprises the following five steps of: (1) determining the acoustic environment functional area category of a monitoring point position, and carrying out noise standard limit value statistics; (2) acquiring noise detection results of the environment, the road traffic and the functional area of the determined area; (3) normalizing the obtained monitoring result corresponding to the noise standard limit value of the monitoring point position, and calculating the sound environment quality sub-index of each monitoring point every day; (4) determining single sound environment quality comprehensive indexes in different evaluation periods and areas according to the single-point sound environment quality sub-index; and (5) performing arithmetic weighted calculation according to categories to determine the acoustic environment quality evaluation index. Three indexes (regional environment, road traffic and functional area environmental noise) of conventional monitoring in the urban acoustic environment functional area are integrated, the acoustic environment quality condition of each area can be evaluated more scientifically and accurately, and decision support is provided for environmental pollution prevention and control.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to an evaluation method for noise environment quality. Background technique [0002] With the rapid development of urban construction, the noise problem has become one of the environmental pollution problems that cannot be ignored. The routine monitoring of the acoustic environment quality in China has continued since the 1970s. The monitoring and evaluation is mainly based on the "Acoustic Environmental Quality Standard" (GB3096). In 2012, the "Technical Regulations on Routine Monitoring of Acoustic Environmental Quality" (HJ640) was promulgated, which further standardized the monitoring and evaluation of the acoustic environment. [0003] According to HJ640 regulations, routine monitoring of acoustic environment quality (also known as routine monitoring) is mainly to carry out a general survey of the acoustic environment, including three parts: regiona...
