IQ Linked to How Well You Hear in a Crowd: New findings could reshape how Thai classrooms and public spaces address listening in noise
In a world full of overlapping conversations, a new line of research suggests that your brain’s cognitive skills may be as important as your ears when it comes to understanding speech in noisy environments. The study, conducted with participants who all had clinically normal hearing, found a strong link between intellectual ability and success at “multitalker” listening tasks. In other words, people with higher cognitive abilities tended to perform better at picking out one conversation from behind a chorus of voices. The finding held across three diverse groups—people on the autism spectrum, individuals with fetal alcohol spectrum disorder, and neurotypical controls—indicating that cognitive processing plays a central role in real-world listening, not just peripheral hearing.
