Influence of the Geometric Features of Obstacles on Noise Reduction of Power Equipment

  • Published:
Power Technology and Engineering Aims and scope

This article investigates the reduction of noise levels due to the shielding properties of obstacles in the form of buildings and barriers in the territory of the thermal power plant (TPP) at the calculation point, located on the border of the sanitary protection zone. The study investigates the effect of the transverse and longitudinal arrangement of buildings in the TPP territory on the sound level at the calculation point from the real noise source of the TPP. Using calculations, the isolines of the noise level after positioning the obstacle at various locations. Owing to the high shielding properties, the transverse arrangement of the building can reduce the sound level at the calculation point by approximately 9 – 11 dBA compared to that of in the longitudinal arrangement. The mutual influence of obstacle height, length, and width of the obstacles on reducing the noise of power equipment is also discussed. It has been established that the building width has no significant effect on noise reduction for calculation points located at a distance of more than 450 m from the obstacle. The calculation results assist in determining the height and length of the obstacle to achieve the required reduction in sound level from the source. Furthermore, specific areas are determined when a change in the length and height of the obstacle does not result in a change in the acoustic efficiency. Finally, recommendations for the installation of power equipment are given to utilize the shielding effect of obstacles.
