Background
At present, the domestic noise model is still blank, and no domestic noise model with public credibility exists in the field of noise models. Noise models used in national environmental assessment are mainly CADNA-A and Lima. The two types of software are noise model software developed abroad and have model calculation functions for urban traffic noise, railway noise and aircraft noise.
The noise map drawing method is characterized in that the noise map drawing field of China starts late, the noise map can visually reflect the pollution characteristics, pollution reasons, pollution trends and pollution control key points of urban noise, and currently, mainstream noise calculation software comes from abroad, so that the function of the calculation software is inconvenient to change in practical use. In practical use, because China still has a certain gap between the map drawing standard and the foreign standard, the calculation function needs to be changed according to different standards. Although some foreign software is purchased and then offered after-sales service, the quality of service is generally not high, and the problem is solved slowly due to time difference. In addition, foreign software is similar to Lima, and the user manual is complicated in content and not beneficial to a novice to quickly master the system functions. In view of this, we propose a noise map-based terminal and method for converting traffic flow into noise data.
