It is a common instinct: when trying to catch a faint sound or focus on a conversation in a crowded room, many people instinctively close their eyes, believing that shutting out visual distractions will sharpen their auditory focus. However, new research published in The Journal of the Acoustical Society of America suggests that this long-held habit might actually be a mistake in noisy environments.

The Study: Vision Meets Sound

The study, titled “Visual engagement modulates cortical criticality and auditory target detection thresholds in noisy soundscapes,” was conducted by a research team including Ke Ni, Yu Huang, Yi Wei, and Xu Zhang. Their findings reveal a complex relationship between our senses that challenges the “eyes closed” strategy.

According to the researchers, while closing the eyes might improve the ability to detect subtle sounds in perfectly quiet conditions, the opposite is true when background noise is present. In noisy settings, participants in the study actually struggled more to detect faint sounds with their eyes closed. Conversely, having their eyes open—especially when visual stimuli matched the audio, significantly lowered the auditory detection threshold, making it easier to hear.

Multisensory Integration

The core of the discovery lies in how the brain processes multisensory information. In “noisy soundscapes,” the brain uses visual cues to help filter and identify auditory signals. “The visual boost comes from the brain’s ability to integrate information from different senses,” the researchers noted.

The team, led by researcher Yu Huang, found that visual engagement modulates “cortical criticality,” a state where the brain is most sensitive to incoming information. When the eyes are open and engaged, the brain appears better equipped to pick out specific sounds from a chaotic background.

Future Directions

The team plans to delve deeper into whether this benefit stems from general visual input or if the brain requires a specific match between what is seen and what is heard. “Specifically, we want to test incongruent pairings—for example, what happens if you hear a drum but see a bird?” said Huang. This will help determine if the “visual boost” is a result of general attention or a specific mechanism of multisensory integration.

Practical Implications

Since everyday life rarely occurs in total silence, the study suggests that keeping your eyes open is likely the more effective strategy for navigating the noisy world. Whether you are in a busy restaurant or a crowded street, your eyes might be doing more for your hearing than you realize.
