Do we need psychoacoustics within soundscape?

چکیده
For the evaluation of soundscape the perception by the human being with respect to the auditory sensation is very important, which is also influenced by expectation, experience and context. The well-known A-weighted sound pressure level is a suitable predictor at higher levels to estimate a possible damage of the human hearing by sound. But at lower sound pressure levels annoyance cannot be sufficiently predicted by the A-weighted sound pressure level. Especially in complex sound situations with different spatially distributed sound sources the human hearing is able to focus on single sound sources and to judge the sound quality depending on loudness, sharpness, roughness, fluctuation strength separately. This means that for the acoustical investigation of soundscape the use of binaural recording and psychoacoustic analysis is strongly recommended, which is currently described as informative in the new working item proposal for ISO 12913-2.

Conducting Psychoacoustic Experiments with the SoundScape Renderer
The SoundScape Renderer (SSR) is a versatile software tool for real-time spatial audio reproduction. It is capable of generating driving signals for a variety of loudspeakerbased and headphone-based reproduction methods. Due to its extensive remote-control possibilities, it can be conveniently used as an audio backend in psychoacoustic listening and conversational experiments, for example in th...

At the quiet and noisy sides of buildings 69 residents of three residential areas found 414 soundscapes to be similar with regard to sounds discerned. The most frequently heard sound was road traffic. At the quiet sides, children playing, talking people, birds and unidentified sounds were more often heard indoors with windows closed than outdoors. Generally, sounds heard outdoors were louder th...

The increase of complaints about environmental noise shows the unchanged necessity of researching this subject. By only relying on sound pressure levels averaged over long time periods and by suppressing all aspects of quality, the specific acoustic properties of environmental noise situations cannot be identified. Because annoyance caused by environmental noise has a broader linkage with vario...

Over the years the environmental potential of urban parks has attracted increasingly attention. In order to preserve their positive influence for communities, the sonic environment perception (soundscape) must be considered too. Urban parks’ sonic environment is influenced by attenders moving around; indeed, walking sounds have very high occurrence in such contexts. However, studies investigati...

This paper examines the concept of "quiet" as an "environmental value" in terms of amenity and wellbeing from a legislative context. Critical review of two pieces of environmental legislation from Australia and New Zealand forms the basis of the paper. The Australian legislation is Queensland's Environmental Protection Act, and the New Zealand legislation is that nation's Resource Management Ac...
