Timbre depends on: Whether the sound is periodic, having a tonal quality for repetition rate of 20-20,000 Hz or having a noise like quality. Whether it is continuous or interrupted. Distribution of energy over frequency i.e.
its spectrum and changes that occur in this spectrum over time. ounds containing predominantly high frequencies have a sharp timbre- whereas those containing mainly low frequencies sound dull or mallow. The components in a complex sound are partially separated by auditory filters and the distribution of the excitation at the output of the filters as a function of centre frequency-determines timbre. TEMPORAL RESOLUTION OF THE EAR: Auditory system is…
