|Description||This paper investigates the ways in which vegetation modifies the human response to sound in an outdoor setting and examines acoustic impacts on aesthetic evaluations of different settings. In particular the researchers were looking for evidence that people perceive that noise has been abated due to trees and shrubs, even where planting is too sparse to produce a physical abatement of noise.|
|Methodology||Following a variety of preliminary studies to establish a research methodology, ten sound stimuli covering a range of sounds heard in urban, rural, and natural settings were selected. These sounds were played to ten student subjects at each of five field test sites ranging form urban to rural in character. The results were compared to the reaction of other subjects to tape-slide presentations. It was found that the procedure used to obtain the results did not influence the results significantly.|
The original research hypothesis was not substantiated. The authors concluded:

There is little research into the acoustic impacts on aesthetic evaluations of the environment. The authors suggest that the reasons for the emphasis on visual features of a setting are twofold. First, that researchers consider visual features of paramount importance and second that there is a lack of generally accepted methods for assessing the aesthetic impact of sounds outdoors. This research addresses the second issue and gives useful guidance on the management of research into the interaction of sound and setting including suggestions for the methodology of future research.
The paper gives interesting examples of how sound and setting interact but does not examine in any depth the role acoustics play in determining our aesthetic response to the natural environment.
