The Positive Soundscapes Project was a unique research effort which sought to re-evaluate environmental sound.

Background:

The project set out to give a rich and rigorous account of human perception of and response to soundscapes. To do this it used overlapping methods from a wide range of disciplines, ranging from the quantitative (e.g. acoustics) to the qualitative (e.g. social science) to the creative (e.g. sound art). Qualitative fieldwork (soundwalks and focus groups) determined that people conceptualised a soundscape into three components: sound sources (e.g. a market), sound descriptors (e.g. rumbling) and soundscape descriptors (e.g. hubbub). Lab-based listening tests along with the fieldwork have revealed that two key dimensions of the emotional response to a soundscape are calmness and vibrancy. In the lab these factors explain nearly 80% of the variance in listener response. Interview responses from real soundscapes further indicate that vibrancy can be expressed in two sub-dimensions expressing variation over time and over sound mix. Physiological validation of the main dimensions is provided by images of changes in the brain during listening from fMRI scans and by changes in heart rate. Artistic work and the public responses to it illustrate the huge range of sounds and soundscapes considered positive. Tools for simulating soundscapes have been developed and seem to be effective for several purposes, including design and public engagement - that is, sound play. The project results will lead to new metrics and assessment methods for soundscapes, new ideas for design and user engagement and, perhaps, better policy on environmental noise.
