Abstract :
Many areas in audio engineering, e.g., perceptual coding, strongly rely on knowledge and models of the human auditory system. Nonuniform frequency resolution and masking phenomenon are well studied aspects. Less attention has been paid to the temporal auditory resolution. In this pilot study the temporal resolution is tested by using short (0.55-4.15 ms) clicks called Bark-FAMlets. They form an orthogonal set of signals all having identical power spectra with uniform masking properties. Individual FAMlets differ only in phase by steps called an auditory unit delay (AUD). We found that 75% discrimination is achieved when the difference between two FAMlets is 22, 11 or 10 AUDs depending on the three test conditions used
