Abstract

The thesis investigates how auralisation and qualitative research methodologies developed in the field of soundscape research, may be applied to the issue of environmental noise in urban areas. The project brings together research and assessment methodologies from traditionally distinct areas in acoustics, and attempts to develop a multidisciplinary approach to solving noise related urban design problems. Within this process, the author also explores the theory that part of a sustainable solution to noise annoyance lies in challenging negative attitudes to noise, particularly in urban environments, where attempts to reduce sound pressure levels are either not feasible or inappropriate. To demonstrate the application of the approach, a case-study is presented involving the auralisation and subjective evaluation of a real-world soundscape before and after the insertion of a sonic crystal noise barrier. The results of the case-study suggest that, with minimal adaptation, certain soundscape assessment methodologies are compatible with virtual acoustic environments. This leads to the conclusion that, using the virtual assessment methodology, one is able to predict with reasonable accuracy the impact of various physical types of noise intervention on the perceived sound quality in urban environments prior to their construction. The author also argues that a greater awareness and appreciation for the multiplicity of sound in urban environments might, in conjunction with sustainable noise control strategies, over more long-term benefits to society than over-speculation concerning the adverse effects of noise.
