Published studies linking working memory to speech-in-noise are underpowered.

Evidence

Correlation coefficients in the surveyed studies are broadly distributed, spanning almost half of the possible range of r values (i.e., from ‑0.29 to 0.58). Confidence intervals (CIs) are generally large and include the null hypothesis in 21/25 and 24/25 cases for CIs of 95 and 99 %, respectively, suggesting that these studies are not appropriately powered. — Dijk, Pim van, Physiology, Psychoacoustics and…, 1123 (#corroborates, via linked claim)
