651 - Prediction and design of noise barriers for stationary noise sources
Tyurina N.
Abstract
Last years noise barriers find wider application to reduce noise emitted by outside stationary equipment, for instance by ventilation equipment, chillers, compressors and other types of energy installations. New theoretical approach is elaborated to predict noise reduction level provided by noise barriers. Developed method takes into account shape of the barrier, its geometrical size, acoustical properties and features of barrier location around the noise source. Barrier design criteria and practical issues are discussed. Efficiency of barriers installed outside around ventilation equipment and compressors obtained from experimental study is in the range 7-15 dBA for a set of specified receivers. Features and principals of noise barriers prediction and design are considered in the paper.
