The Effect of Room Acoustics on the sleep Quality of Healthy sleepers

This study examined the impact of room acoustics on sleep quality by comparing sleep in three environments: a sleep lab, an acoustically isolated room, and participants’ homes. Results showed that sleeping in an acoustically isolated room significantly increased deep sleep and reduced arousals compared to other settings. However, subjective sleep quality ratings were highest at home. These findings highlight the importance of noise reduction and soundproofing to enhance the restorative aspects of sleep, especially deep sleep, which is critical for brain recovery and health.

To improve sleep quality, especially deep sleep, consider enhancing bedroom acoustics by reducing noise and minimizing sound reverberation. Options include using soundproof materials, noise-canceling devices, or maintaining a quiet sleep environment. While these findings are based on healthy sleepers in controlled settings, they underscore the benefits of quiet environments for restorative sleep and cognitive performance.
