Acoustic analysis of perceptual sound categories Laurie M. Heller Benjamin Skerritt 10.1184/R1/6613301.v1 https://kilthub.cmu.edu/articles/journal_contribution/Acoustic_analysis_of_perceptual_sound_categories/6613301 <p>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.</p> 2010-03-01 00:00:00 psychology
