title: How to select stimuli for environmental sound research and where to find them.
abstract: A major methodological challenge in environmental sound research is to select appropriate stimuli. When an experiment involves a large number of sound sources, making custom recordings orproducing sounds live is frequently impractical or, for certain sounds, impossible. Existing databases of environmental sound recordings provide a researcher with a useful alternative. However, finding and selecting suitable sounds in such databases can be difficult because of the great variety of sounds present, poor documentation, questionable recording quality, and required purchasing costs. This article describes a number of practical issues to consider during the stimulus selection process, offers a preliminary compilation of existing resources for obtaining environmental sound recordings, provides some normative perceptual data that can be used as a reference for selecting stimuli and evaluating performance, and lists required characteristics and structural aspects of a research-oriented environmental sound database.
