Erratum: “The effect of signal-temporal uncertainty on detection in bursts of noise or a random-frequency complex” [J. Acoust. Soc. Am. 124(5), EL321–EL327 (2008)

Abstract

Several programming errors were discovered subsequent to publication. These errors were the authors' mistake and resulted in discrepancies between the reported and actual duration of stimuli and the timing of stimulus presentations. The signal was 125 ms, including a 5-ms, linear onset/offset ramps. Each masker burst was 125 ms in duration, including a 5-ms, linear onset/offset ramps. One masker component was selected from the uniform distribution of 300 to 920 Hz and the other component from the distribution of 1080 to 3100 Hz. A 5-ms period of silence occurred after each burst of the continuous masker. When a signal was present, it was played 80 ms after the onset of the fourth masker burst, from when the trial was initiated. Results from three trained listeners, who were not in the original data set, indicate that these programming errors did not change the size of the effect of signal-temporal uncertainty in the broadband noise condition for any of the listeners nor in the random-frequency, two-tone masker condition for one of the listeners. In the latter condition, the effect size was 4 and 6 dB larger for two of the listeners when the errors were corrected compared to when they were not.
