Abstract

Uncertainties in prediction of ground effect along the path from noise sources to distant receptors may have serious implications on the recommended separation distance or the extent of other noise mitigation measures designed to ensure compliance. The results of noise impact assessment for a proposed noisy facility based on a procedure predicting unrealistically high values of ground attenuation may prompt an approval agency to recommend a relatively small separation distance between the facility and noise sensitive receptors which will lead to excessive sound levels and, consequently, to an adverse community reaction. Conversely, an assessment based on an assumption of very low ground absorption loss contribution may result in specification of a large buffer zone and, consequently, the sterilization of land available for development, or to excessive noise abatement recommendations directed at the source to ensure compliance
