Detectability alone fails to capture what hearing benefit users deem meaningful

Evidence

To ascertain what is a meaningful benefit to someone requires more than detectability; it requires the subjective input of the participant. The previous method for deriving the SNR JND was hence changed to subjective-comparison tasks using SNR and SNR + ΔSNR pairs as examples of, respectively, pre-benefit and post-benefit situations to measure the “just meaningful difference” (JMD) for SNR. — Dijk, Pim van, Physiology, Psychoacoustics and…, 5684

Categorization

• DEFINE: Introduces the JMD (just meaningful difference) as distinct from the JND (just noticeable difference).
