What brown noise is
Brown noise (also called red noise) emphasizes low frequencies — a deep rumble compared to white noise hiss. Integrated random walk synthesis creates its characteristic waterfall sound.
Popular use cases
Sleepers who find white noise too bright often prefer brown noise for masking traffic rumble. Students use it to cover keyboard clatter. Audio testers use it to stress low-frequency speaker response at moderate volume.
Listening tips
Phone speakers may not reproduce the deepest bass — headphones or desk speakers reveal the full character. Keep volume moderate for long sessions to protect hearing.
