This rhythm helps quiet racing thoughts without demanding attention. The low-frequency rumble of brown noise is particularly effective for ADHD brains that struggle to switch off at night. Designed for insomnia, racing thoughts at bedtime, tinnitus relief, and sensory processing differences. No sudden sounds, no volume changes, no mid-roll ads — just steady audio all night.
