The just-noticeable difference for speech in noise was nearly unstudied until recently

Evidence

The current study looked at both of these: how large a change in signal-to-noise ratio (SNR) has to be for it to psychophysically discriminable or clinically meaningful. This is a curiously under-studied area: previously there has been only one small study related to measuring the just-noticeable difference (JND) in SNR by Killion ( 2004 ), in which unspecified participants were at chance discriminating a 2 dB SNR difference for speech in noise. — Dijk, Pim van, Physiology, Psychoacoustics and…, 5669

• QUESTION: This JND finding sits near the core of the reader’s psychoacoustics interest but the passage gives only initial framing; worth reconfirming later.
