Brown Noise for 8 hours
Brown Noise for 8 hours is ideal for full night sleep, workday coverage, all night study session. Eight hours is the sleep standard - long enough to cover a full night's rest with margin.
Brown noise is named after Robert Brown and Brownian motion — not the colour. It emphasises low frequencies, losing about 6 decibels per octave as frequency rises, producing a deep, warm, enveloping sound often compared to a strong waterfall, distant thunder, or the low rumble of a jet engine from inside the cabin. Brown noise exploded on TikTok in 2022 when ADHD communities discovered that the deep, consistent sound seemed to "quiet their brains" in a way other sounds didn't. The hashtag #brownnoise accumulated over 100 million views. The theoretical basis is stochastic resonance — external noise helps understimulated brains reach optimal processing levels. While the 2024 Nigg meta-analysis found no peer-reviewed studies specifically on brown noise (all clinical evidence uses white or pink noise), the mechanism applies to broadband noise generally, and the anecdotal evidence from millions of users is overwhelmingly consistent.

8 Hours — quand utiliser
Eight hours is the sleep standard - long enough to cover a full night's rest with margin. However, the latest research (Basner et al., 2025, UPenn) suggests that continuous sound exposure during sleep may reduce REM sleep by 18-19 minutes. For optimal results, use Softly's sleep timer to fade the sound after 45-90 minutes rather than playing through the entire night. The sound helps you fall asleep; silence lets your brain cycle through REM undisturbed.
