Theoretical and applied environmental sounds research is gaining prominence but progress has been hampered by the lack of a comprehensive high quality accessible database of environmental sounds. An ongoing project to develop such a resource is described which is based upon experimental evidence as to the way we listen to sounds in the world. The database will include a large number of sounds produced by different sound sources with a thorough background for each sound file including experimentally obtained perceptual data. In this way DESRA can contain a wide variety of acoustic contextual semantic and behavioral information related to an individual sound. It will be accessible on the Internet and will be useful to researchers engineers sound designers and musicians. 1. Introduction Environmental sounds are gaining prominence in theoretical and applied research that crosses boundaries of different fields. As a class of sounds environmental sounds are worth studying because of their ability to convey semantic information based on complex
