Traffic Noise Analysis System Based on Forest Belt

Abstract

The invention provides a traffic noise analysis system on the basis of forest belts. The traffic noise analysis system comprises a noise simulation device, noise analyzers and terminal equipment. The noise simulation device is used for transmitting linear sound sources towards the forest belts at preset frequencies so that noise of vehicles can be simulated; the noise analyzers are used for receiving linear sound sources which are transmitted through the forest belts, analyzing and processing the linear sound sources to obtain equivalent continuous sound pressure values corresponding to the linear sound sources, transmitting the equivalent continuous sound pressure levels to the terminal equipment and adjusting working states of the noise analyzers according to control instructions of the terminal equipment; the terminal equipment is used for receiving and displaying the equivalent continuous sound pressure levels and controlling the working states of the noise analyzers according to control instructions of testing personnel. The traffic noise analysis system has the advantages that the locations of multiple points in the forest belts can be simultaneously measured by the multiple noise analyzers at the same moment according to control of the terminal equipment, data are continuous, and the traffic noise analysis system is high in test precision; scientific and accurate numerical values of the equivalent continuous sound pressure levels can be obtained and can be checked by the testing personnel by the aid of the terminal equipment, and accordingly the traffic noise analysis system is convenient and speedy.

Description

technical field [0001] The invention relates to the technical field of instruments and meters, in particular to a forest belt-based traffic noise analysis system. Background technique [0002] With the world's attention to noise pollution and the strengthening of noise control and governance, the demand for noise measuring instruments is increasing year by year, and they are widely used in noise detection in different fields such as construction, transportation, industrial enterprises, and social life. Accurate measurement and analysis of noise signals is a prerequisite for targeted prevention and control of noise and effective solutions to environmental noise pollution. [0003] Traffic noise affects people's normal life. On different roads, the frequency of traffic noise produced by different passing vehicles is also different. In order to reduce the impact of traffic noise on residents' normal life, forest belts are usually planted on both sides of the road. , in order t...
