SONUS
Auditory Sleep Protocol: SONUS
Mask disruptive noise to prevent nocturnal arousals
A part of your brainstem called the reticular activating system stays half-awake all night, scanning for irregular sounds. A car door. A neighbor. A snore. SONUS raises the noise floor so those spikes don't register.
A 2021 meta-analysis in Sleep Medicine Reviews (n=8,242) found white noise reduced sleep onset latency by 38% compared to silence in noisy environments.
