Assessment of engineering equipment noise impact of agricultural enterprise on the adjacent residential building

Abstract

A significant source of increased noise in cities is the engineering and technological equipment of enterprises located in immediate vicinity of standardized objects. The expected noise levels from technological and ventilation equipment of an agricultural enterprise located in the city are estimated. A computer model of the territory under consideration is built using the software package “ARM Acoustics”. As the initial data, the results of field measurements were used. The calculation of the expected noise levels near the facades of residential buildings showed the excess of regulatory levels. It is shown the necessity to install noise screens not only near equipment located on the ground, but also near equipment installed on the roof of the industrial building. The calculation was carried out taking into account the location of the U - shaped screens, which provided effective protection against noise. To illustrate the effect obtained, maps of the spatial distribution of noise are constructed.
