Shorter masker and test-tone durations flatten the lower slope of pulsation patterns

Evidence

The results plotted in Fig. 4.36 show that the shape of the pulsation pattern depends slightly on the choice of the duration of “masker” and test tone. In particular, the steepness of the lower slope of the pulsation pattern decreases somewhat with decreasing duration of “masker” and test tone. — Professor Dr.-Ing. Hugo Fastl, Professor Dr.-Ing.
