Low-side suppression operates at very low sound levels in ANFs

Evidence

Low-side 2TS-threshold estimates are surprisingly low (Fig. 3a and b ). All fibers had low-side suppressive regions, regardless of hearing status, typically in the region of 0- to 20-dB SPL. — Dijk, Pim van, Physiology, Psychoacoustics and…, 3852

Categorization

• QUESTION: Why are low-side suppression thresholds so low compared to excitatory thresholds? What mechanism makes low-side suppression detectable at 0-20 dB SPL?
• CANDY: A fiber’s low-side suppression region responds at whisper-quiet levels even in damaged ears, while its excitation needs far more sound.
