Accuracy and Disclaimer

Last updated 2026-08-14.

Use the results, but check them

Tinglissimo is built to be accurate and is tested against known reference values. It is still software written by people, running in a browser we do not control, on input we cannot see. Treat every result as a well-informed starting point rather than an authority.

Before you rely on a result for anything that matters — money owed to someone, a legal or tax position, a medical decision, a machined part, a navigational fix — check it against a second source.

Specific limits of this site

Sound played through headphones can damage hearing, and the risk depends on level and duration together — a quiet level for eight hours a night is a long exposure. This site starts at a fifth of full volume and fades in, but it cannot detect or control your device volume. Set it low, and lower still for overnight use.

No claim is made that any sound here improves sleep, concentration, anxiety or any other condition. What can be said is narrower: continuous background sound masks sudden changes in noise, and some people find that helpful. Some people sleep worse with sound in the room, which is a normal outcome and not a fault in the tool.

Binaural beats are generated exactly as described — two tones a few hertz apart, one per ear — and require headphones to work at all. The popular claim that they drive brainwave activity into a matching state is weakly evidenced, and the band names in the interface label frequency ranges rather than promise states.

Anyone with epilepsy or a seizure history should treat rhythmic audio stimulation as something to raise with a qualified professional rather than to experiment with.

The sounds are synthesised approximations, not recordings of real places. Rain here has no roof, the ocean has no shoreline and the fire has no room. That is the trade that buys instant playback, offline use and no repetition.

Audio output depends on your browser, your operating system and your hardware. Some mobile browsers suspend audio in a background tab, and small speakers cannot reproduce the low-frequency content of brown noise or ocean swell at all.

Not professional advice

Nothing on this site is health, sleep, hearing or other professional advice, and using the sound generator does not create a professional relationship of any kind. If a decision has real consequences, ask somebody qualified and accountable.

Liability

Our liability for the results this site produces is limited as described in the Terms of Service. In short: the site is free, it is provided as-is, and we cannot accept responsibility for losses caused by relying on it without checking.
