In Brief:
This study investigated the effect of musical training on understanding speech-in-noise (SIN), a complex task requiring the integration of working memory and stream segregation, and the detection of time-varying perceptual cues. Previous work in SIN has focused on populations who experience difficulty in noise, but not auditory experts. Musicians outperformed nonmusicians on SIN measures, which may be derived in part by musicians' enhanced working memory and frequency discrimination. Furthermore, SIN performance (QuickSIN), working memory, and frequency discrimination were positively correlated with years of musical practice. Results are consistent with the notion that training in one domain (music) can transfer to another (speech) and provide insight into factors that positively impact speech perception in noise, possibly leading to more effective remediation strategies for clinical populations.
