title: Hearing threshold for a decaying oscillatory waveform.
abstract: Hearing thresholds for a damped wave signal are measured at 8 frequencies from .35 -- 4 kc/s, and compared with hearing thresholds for pure-tone signals of the same frequencies. Hearing threshold for a damped wave signal is expressed in peak db re 20 uPa. Differences range somewhat irregularly from 8.6 to 19.6 db in favor of pure-tone signals. The difference between both threshold levels is described by a simple model.
