The term 'soundscape' — the acoustic equivalent to 'landscape' — is relatively new to many. The present report summarises the results of the conference Designing Soundscape for Sustainable Urban Development, which was organised in order to introduce the soundscape approach to architects and urban planners who have little or no previous experience in this field. Like the conference, the present report seeks to inspire and provoke new thoughts in order to challenge the visual dominance in architecture. In order to reach this objective I invited among the finest soundscape experts in the world to present their thoughts and case studies for others to follow. By the present report they provide their contributions in written form for those who could not participate in the conference. I am convinced that these thoughts will change the way you perceive the built environment, as well as the way you think about and listen to sounds. The report makes evident that the soundscape is an essential environmental resource.
