Common Uses
Focus & Concentration
Pink or brown noise masks distracting sounds and creates a consistent acoustic environment. Used in offices, libraries and study spaces.
Sleep
Brown noise is particularly effective for sleep — its low-frequency emphasis is reminiscent of rain, wind and ocean sounds.
Speaker Testing
White noise tests the full frequency response of speakers and headphones. Pink noise is used for calibrating mixing rooms and PA systems.
Sound Design
Noise is the foundation of synthesis — filtered white noise creates breath, wind, ocean, rain, steam, static and textural pads.
Tinnitus Masking
Many people find that continuous noise — especially pink or brown — helps mask tinnitus and reduces its perceived volume.
Production Reference
Pink noise at a known LUFS level is used to set monitor volume for critical listening — a consistent reference point for every session.
White noise has equal energy at every frequency — harsh, like TV static.
Pink noise rolls off at 3dB per octave — balanced, like a waterfall or rain. Most natural to human hearing.
Brown noise (Brownian/red) rolls off at 6dB per octave — deep, warm, like thunder or heavy rain.
Blue noise increases at 3dB per octave — bright, airy, hiss-like.
Violet noise increases at 6dB per octave — very bright, almost painfully sharp.
