Determination of the Main Source of External Noise Caused by the Enterprise Engineering and Technological Equipment in the Residential Development Area

Abstract

The article considers two approaches to solving the problem of searching sources that make the greatest contribution to noise levels in the residential area caused by the enterprise engineering and technological equipment operation. The first approach is based on the analysis of the sound pressure levels in 1/3 octave frequency bands, the second one – of the levels of its narrow-band spectrum. It is determined that the results obtained using narrow-band analysis (Δf=1 Hz) provide more accurate results.
