White Noise Boosts Hearing (11-14-19)

Christensen, Lindén, Nakamura, and Barkat determined that white noise can improve ability to hear other sounds and their work is published in Cell Reports.  The investigators found via studies with mice that “With a background of continuous white noise, hearing pure sounds becomes even more precise. . . .the more precisely we can distinguish sound patterns, the better our hearing is. But how does the brain manage to distinguish between relevant and less relevant information – especially in an environment with background noise? . . . The team was able to demonstrate that the brain’s ability to distinguish subtle tone differences improved when white noise was added to the background. Compared to a quiet environment, the noise thus facilitated auditory perception.”
