Temporal gap detection thresholds are measured with a three-alternative forced-choice task

Evidence

Experiment III tested the temporal gap detection (TGD) threshold for all subjects using a TGD program developed by Zeng et al. ( 1999 ). The test stimuli were generated using a broadband (from 20 to 14,000 Hz) white noise. The noise had a duration of 500 ms with 2.5-ms cosine-squared ramps. A silent gap was produced in the center of the target noise. The other two reference noises were uninterrupted. The TGD threshold of left and right ear was measured separately for each subject using a three-alternative, forced-choice procedure. — Dijk, Pim van, Physiology, Psychoacoustics and…, 3395
