چکیده
The objective of the study is to develop GIS based noise simulation software for heterogeneous traffic conditions in metropolitan cities. In the present study traffic noise simulation software has been developed for sound level calculation. The software covers the following five input variables i.e., noise sources (point and mobile), vehicle speed, distance, honking and noise attenuation while noise Leq is the output of the software. The software is implemented for traffic noise level prediction at eight selected loc ations of Nagpur city. The field data is collected for a period of 15-minutes during the morning and evening rush hours. The correlation coefficient between measured and predicted noise Leq found to be 0.84. Results show that the software performs reasonably well for heterogeneous traffic condition and could be implemented in other region for noise level prediction.

متن کاملSimulation and Experimental Study of Vibration and Noise of Pure Electric Bus Transmission based on Finite Element and Boundary Element Methods
Since the electric motor of pure electric vehicle replaced the engine, the "masking effect" disappears, and the problem of vibration and noise of the transmission becomes prominent. This is generated during the gear meshing and is transmitted to the housing through the shaft and bearing. Thereby, radiation noise of the housing are generated. The prediction and analysis...

The purpose of this paper is to improve the modeling of the data-driven wind turbine system that receives data from noise signals. Most of the data on industrial systems is noisely and data noise is inevitable and natural. The method and idea proposed in this paper, Data Fogging, significantly reduce the impact of noise on data-driven wind turbine system modeling, which is the basis of this met...
