A 3 dB detectable SNR change is far too small to motivate intervention-seeking behavior

Evidence

For the + 6 dB SNR reference condition, mean responses never significantly exceeded chance; furthermore, the function appears asymptotic, so the responses may not have exceeded chance regardless of the change in SNR. If the SNR is already relatively high enough to be clear, then making it clearer still does not appear to induce intervention-seeking behaviour. — Dijk, Pim van, Physiology, Psychoacoustics and…, 5711 (#corroborates, via linked claim)
