Abstract
Intensity discrimination functions were determined for tone bursts at four test frequencies: 250, 1,000, 4,000, and 7,000 Hz. Slopes of best-fitting lines (αI in dB SL vs I in dB SL) indicate a “near-miss” to Weber’s law at all four frequencies. The use of information provided by harmonics of the stimulus is discussed; it is concluded that-at least for high-frequency tones-such cues are not the basis for the improved acuity found at higher sensation levels.
