Noise Mask
White, pink and brown noise generated live in your browser — no downloads, no account, works offline once the page is loaded.
Noise masking helps many sound-sensitive people, not everyone. In one clinical study of autistic minors (n=54), white noise via headphones improved attention and behaviour scores for most participants — but a meaningful group, especially those without intellectual disability, did not tolerate it at all. The rule this page lives by: if the mask adds load instead of removing it, turn it off. Your sensory system gets the deciding vote, every time.
🔒 The noise is synthesised on your device — no audio files download, no microphone is used, no network call after the page loads. · Evidence: Salmerón Medina et al. 2025 (Behav Sci, white noise in autistic minors — improvements plus documented intolerance in a subgroup). · For comfort, not treatment.
