Block Out Distractions with Noise & Ambient Sound

Why Use This Tool?
Six Sound Types
Choose from white, pink, and brown noise plus ambient rain, ocean waves, and forest sounds — each synthesised with layered algorithms for a natural, loop-free listening experience.
Sleep Timer
Set a 15-minute, 30-minute, 1-hour, or 2-hour timer and the audio stops automatically — so you can fall asleep without worrying about leaving your browser running all night.
Runs Entirely in Your Browser
Generated noise uses the Web Audio API — no files to download, no plugins required. Works on desktop and mobile browsers without any installation.
Stereo Ambient Sound Design
Ocean waves shift gently between left and right channels, rain drops are spatialised, and forest sounds include layered wind, bird calls, and rustling leaves for true immersion.
How this White Noise Generator works
This audio relaxation tool generates six types of ambient sound—White Noise, Pink Noise, Brown Noise, Rain, Ocean Waves, and Forest Ambience—using the Web Audio API directly in the browser. Each sound type offers distinct acoustic properties suited to different relaxation, focus, or sleep needs.
White noise contains equal energy across all frequencies, creating effective sound masking. Pink noise emphasizes lower frequencies for a more balanced, natural sound. Brown noise provides deep, rumbling tones many find especially soothing. Ambient options simulate natural soundscapes including rainfall patterns, ocean wave rhythms, and forest atmospheres with subtle variations.
Volume controls and optional sleep timers (15 minutes to 2 hours) enable customized listening sessions. Visual feedback shows active playback status with animated wave indicators. All audio generates client-side without requiring downloads or external streams, ensuring instant playback and complete privacy. Applications include improving focus during work, facilitating sleep, masking environmental noises, or creating calming atmospheres.
