Abstract

Vegetation belts may offer an effective and economical solution for reducing noise pollution as an environmental impact where sufficiently large areas are available. However, the complexity of the attenuation process makes choosing the right plant species or variety a complicated task. That studies have employed different methods to examine the noise-reducing properties of individual hedges and shrubby groups of trees only complicates matters further. The present study interprets and summarises the achieved results via an analysis of the relevant literature using statistical methods. We focused on the following areas: (1) commonness and value range to compare the general data of the selected studies, (2) location types and the measurement layouts, (3) the parameters used to describe the vegetation strips, and (4) the parameters used for noise measurement and attenuation calculation. In addition to the diversity of the examined environment and vegetation in the studies, the description of the implementation and physical characteristics of the measurements was, in many cases, incomplete in several aspects. At the same time, the differences between the employed parameters and their evaluation resulted in partially comparable noise attenuation data, thereby increasing the inhomogeneity in the literature.
