Intensity preception. VI. Summary of recent data on deviations from Weber’s law for 1000-Hz tone pulses

Data from 15 modern studies are used to characterize the deviations from Weber’s law for intensity discrimination of 1000-Hz tone pulses. The results show that Weber’s law is satisfied in the region 10–40 dB SL, that resolution descreases with decreasing intensity below 10 dB SL and increases with increasing intensity above 40 dB SL, and that resolution at 90 dB SL is roughly 2.5 times better than at 40 dB SL. Subject Classification: [43]65.50, [43]65.75.
