As a particularly insidious form of psychological torture, Bob makes Dylan do a lengthy and boring psychophysical experiment involving the method of constant stimuli. The experiment's aim is to determine his absolute threshold for detecting a sound stimulus, whose pressure is measured in micropascals. After fitting a Weibull function to Dylan's data, Bob finds that his alpha parameter is 3 and his beta parameter is 4. Calculate Dylan's 83% threshold.
