This paper examines how intensity discrimination depends on the test frequency, the level, and the subjects’s high‐frequency hearing. Three experiments were performed. In the first experiment, intensity discrimination of pulsed tones was measured as a function of level at 1 and 14 kHz in five listeners. Results show less deviation from Weber’s law at 14 kHz than at 1 kHz. In the second experiment, intensity discrimination was measured for a 1‐kHz tone at 90‐dB SPL as a function of the cutoff frequency of a high‐pass masking noise in two listeners. Results show that the audibility of very high frequencies is important for frequency discrimination at 1 kHz. The DL increased by a factor between 1.5 and 2.0 as the cutoff frequency of the noise was lowered from 19 to 6 kHz. In the third experiment, thresholds from 6 to 20 kHz and intensity discrimination for a 1‐kHz tone was measured in 12 listeners. Results show that the DLs at 80‐dB SPL are correlated with the ability to hear very high frequencies. Results of all three experiments are consistent with the multiband version of the excitation‐pattern model for intensity discrimination [Florentine and Buus, J. Acoust. Soc. Am.70, 1646–1654 (1981)].
