Dear list, I need information about the way intensity slope of a single sine wave can change the perception of the tone between 2 situations: a) Sine wave which increases its intensity. b) Two distinct successive sine wave with the same frequency, and different intensity. I do not look for streaming experiments such as Van Noorden's from 1977 (ABAB sequence with alternating amplitudes), but rather a single AB, in which B is amplified A, and the variables are the amplitude ratio and duration. Thanks in advance, Alon Fishbach alon(at)
