#NoiseSensitivity

A growing body of research reveals why some people struggle to concentrate or converse in noisy settings—an issue many Thais know from Bangkok’s busy streets, crowded markets, and lively family gatherings. The findings point to a brain-based reason: the insular cortex, or insula, a region that links emotion and perception, may be wired differently in those who are highly sensitive to background sound.

Researchers studying resting-state brain activity found that people who find conversations hard to follow in noise show stronger connections between the left insula and auditory regions. These patterns persist even when the person is not actively listening, suggesting a lasting difference in baseline brain connectivity. Such insights shift the view from personal fault to natural variation in brain organization.

A new wave of research has illuminated why certain individuals find it nearly impossible to concentrate or communicate in noisy environments—a challenge familiar to many Thais contending with Bangkok’s bustling streets or the energetic chaos of family gatherings. Recent findings reveal that this heightened sensitivity to background noise may be hardwired in the brain, specifically rooted in the structure and connectivity of the insular cortex, or “insula,” an area crucial for integrating emotional and sensory information.
