Gap detection thresholds improve sharply with level up to about 30 dB SL

Evidence

At very low stimulus levels, gap detection thresholds decreased (they improved) with increasing level. At 10 dB sensation level (SL), gap detection thresholds were around 20 ms and decreased to slightly less than 3 ms between 10 and 30 dB SL. Once the stimulus level reached about 30 dB SL, further increases in stimulus level were not associated with increased performance. — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 963

• QUESTION: Why does gap detection plateau exactly near 30 dB SL — does this mark a transition in neural coding strategy?
• SHARE: James Alathram would appreciate the concrete 20ms-to-3ms level curve as a quantitative anchor.
