Some Notes on Frequency Discrimination and Masking
In order to study frequency discrimination near and at the threshold of masking, a paradigm was used which permitted frequency discrimination and detection of noise-embedded sinusoids to be measured in one experiment. The just noticeable difference in frequency at the threshold of detection was found to be Δf″ ≈ 16 Hz with durations of the sinusoid of Δt = 64 ms and with Δt = 256 ms. With Δt = 16 ms, Δf″ ≈ 64 Hz. The frequency of the sinusoids was 1000 Hz in all experiments. The possible implications for a place theory and a periodicity theory of pitch perception are mentioned.
