By Audrius Viplentas


Due to the environmental conditions for the infrasound range noise research are exalted stringent requirements. This article gives an overview of the peculiarities of the measurement conditions, which may affect the objectivity of determining sound components in the noise. It was found that for the preliminary infrasound assessment from the source spread noise is enough A and C sound presssure level weighting. If LC - LA more than 15 dB, these noises are significant for acoustical polution. A detailed infrasound study are conducted by G-weighted sound pressure levels in standard frequency bandsVytauto Didžiojo universitetasŽemės ūkio akademij
