Estimating the meteorological parameters impact on the propagation distance of acoustic noise pollution in residential areas

Bulkin V.V., Kirillov I.N.

Acoustic noise pollution of residential areas is becoming an increasingly serious problem. The analysis of possible noise propagation deep into residential areas is to be carried out both on the basis of noise spectral characteristics and the existing peak noise signals as well as the average or local meteorological conditions prevailing in the area. The paper analyzes possible signal attenuation ratio variation for different frequencies when changing the basic meteorological parameters such as ambient temperature, humidity and atmospheric pressure. The simulation results are presented as graphs. Temperature changes effect signal attenuation at most: within 30 to −20оC range, signal attenuation value can be increased from 29.4 dB/km up to 170.5 dB/km.

Keywords: acoustic noise, acoustic signal attenuation, frequency, temperature, humidity, pressure.
