Development of Design and Engineering Solutions to Reduce Noise from the Boiler Room to Protect the Residents

Abstract

The problem of noise effect of a city boiler house on a residential area is considered. Experimentally determined sound levels in the territory of the settlement, in the near and far field of the power equipment of the enterprise. Experienced by installing the main sources of noise from the composition of boiler equipment, their characteristics. A reliable method for determining these sources was the comparison of the spectral characteristics of vibrational and acoustic signals obtained experimentally. With the help of the software complex AWM "Acoustics" an acoustic map of the study area was simulated. As a source data, a terrain map and experimental values of the sound level at the designated control points were used. The acoustic model was used to evaluate the effectiveness of various options for technical solutions that could be implemented to provide the required noise level in a residential area. A set of measures is proposed that allows to significantly reduce the influence of the boiler house on the environment.
