     the influence of climatic factors and the ground surface on the required noise abatement from the power equipment is analyzed. it is shown that annual oscillations of temperature and humidity lead to substantial variations in the levels of the sound and the sound pressure from the same source in the design point, while the ground effect surface can in some cases cause an increase in the sound pressure levels in the design point, and in other cases—their decrease. when developing the measures on sound suppression of the power equipment, it is recommended to take into account the influence of climatic factors depending on annual variations in temperature and humidity for this terrain as well as on the category of the ground surface.
