 The Perception of Quality: Auditory Timbre

Show Summary Details


The sound reaching the observer is the result of the discrete frequency source excitation being filtered by the sound body resonances, analogous to that for color stimuli. However, the interactive coupling between the source frequencies and sound body resonances creates a complex acoustic stimulus that changes across time. The spectral centroids and the onset transients of sounds determine the judged similarities among timbres. The ability to identify properties of objects (e.g., hardness and shape), and the ability to detect the identity of singers and instruments at different frequencies (i.e., constancy) depends on the overall context.

Keywords: coupling; discrete source frequencies; object properties; onset transient; sound body resonances; spectral centroid; timbre constancy
