Making already-clear speech clearer does not motivate people to seek help
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
If the SNR is already relatively high enough to be clear, then making it clearer still does not appear to induce intervention-seeking behaviour. The JMD derived from clinical significance is the same as the JMD derived from the swap task: at least 6 dB SNR. — Dijk, Pim van, Physiology, Psychoacoustics and…, 5684

- XREF: connects to: A 3 dB detectable SNR change is far too small to motivate intervention-seeking behavior; When speech is already clear, further SNR improvement does not motivate clinic attendance; Dialogue-based depolarization interventions produce small, short-lived effects that fail to scale. — Derek E.
