MAIN FINDING: Neural signatures of story listening are impacted by background noise, altering brain activity patterns.
KEY EVIDENCE: Increased speech masking leads to idiosyncratic activation in auditory regions, while effort-related networks show similarity across listeners.
APPROACH: Functional magnetic resonance imaging was used to study brain activity in humans listening to stories amidst 12-talker babble noise.
SIGNIFICANCE: Findings suggest that cognitive processes for understanding speech remain intact under moderate background noise, highlighting listener engagement.
