Acoustic analysis of perceptual sound categories

Acoustic analyses were conducted on several groups of sound events. The sound events were derived from a combination of physical analyses and perceptual data. The acoustic analyses utilized both low‐level properties, such as spectral centroid, and higher‐level properties. The higher‐level properties were based on a combination of the physical sourcecharacteristics of basic classes of sound‐generating events, statistical methods, and perceptual characteristics. A range of metrics are used to evaluate the success and generality of these acoustic properties, including classification performance and comparison to other results in the literature.
