Synergetic noise in residential areas under annoyance evaluation an interdisciplinary concept

摘要

Under aspects of environmental-acoustical exploration the question of annoyance caused by effects on noise plays a particular role. Literature-studies show that the results of different laboratory-studies on annoyance and disturbance of noises are critically to be judged.[1,2,3] When you compare the results of laboratory- and field-studies on annoyance and disturbance of noises, it shows that the appraisal of noises from different sources in laboratory-studies in which dose-response-relationshipnoises were analyzed, the assessment of noise with different characteristics does not display any difference, while in field-studies clear differences in reference to the noise of different sources can be analyzed. Although the source-character of a noise has considerable influence on the effects on noise, this cannot be proved in laboratory studies [4]. That means tendency-wise, that in traditional laboratory-studies the context is faded out, while the effects of context in field-studies play a decisiverole. In addition to a field-study the evaluation of annoyance caused by noise allows to consider different factors in a situation where noises are combined. However it is difficult to describe this complex situation with an adequate potential of methods. The question that has to be discussed is: if sounds are synergistic, which criteria and kind of sources are dominant for the person who assesses the noises? Likewise central is the question for the subjective synergism of noises, i.e. the distribution of noise effects on a person over a certain term and the effect on her/his judgment to annoyance and disturbance of noises.
