Level changes without SNR changes feel at least as beneficial as SNR changes

Evidence

That is, a change in level without a change in SNR was considered as good as—indeed if not better than—a change in SNR. While this finding does not coincide with their role in intelligibility, it is coincident with detectability of level and SNR changes (JNDs of 1.5 and 3.0 dB, respectively). — Dijk, Pim van, Physiology, Psychoacoustics and…, 5669 (#complicates, via linked claim)

Categorization

• XREF: connects to: Pure level changes are rated as valuable as SNR changes despite not aiding intelligibility; Listeners value a level change as much or more than an equal-dB SNR change; Listeners value loudness increases as much as SNR improvements they provide — Dijk, Pim van, Physiology, Psychoacoustics and…, 5686 (+1 more)
