Abstract

At the suggestion of Professor A. Lande the principle adopted is Δv. At = 1, where v is the intrinsic frequency of an acoustic signal and At is its time duration. Applying this principle one finds that it is consistent with experiments on the change in v in the vibrato and the failure to detect it by ear, with recorded tests on minimum perceptible differences in frequency, and with the minimal time for tone perception.. The problems suggested by the principle are: (1) Variations in At and Av by an artificial vibrato with aural observations of detectable Av, (2) redetermination of minimum perceptible differences in frequency as dependent upon At and (3) an examination of At required for tone perception with varied values of Av required for so-called tone perception.
