Many computational models of auditory processing can account well for the perception of steady sounds. However, current models do not explicitly incorporate mechanisms dedicated to the processing of the dynamic frequency changes that occur in most everyday sounds. A series of experiments is proposed to investigate the nature and limitations of dynamics frequency processing by the normal human auditory system. The following questions are addressed: (i) Are frequency changes processed by dedicated mechanisms? (ii) If so, do these mechanisms encode the direction of the changes, or just their presence? (iii) What are the limitations on the ability to process rapid frequency changes? (iv) Do those limitations depend on the nature of the processing task (e.g. detecting a rapidly changing mistuning between two sounds versus making an explicit judgement about a frequency contour)? (v) Do the limitations depend on the way in which the frequency change is encoded by the peripheral auditory system? The results will provide much-needed information to guide the future development of computational auditory models.
