Terms of Use

Last updated: June 27, 2026

By using TestTones (testtones.com), you agree to these terms. If you don't agree, please don't use the site.

Free, as-is service

TestTones is provided free of charge for personal, non-commercial use. It is offered "as is" and "as available," without warranties of any kind, express or implied. We do our best to keep the tones accurate and the site online, but we don't guarantee uninterrupted access or that the site will be error-free.

Use it safely

Test tones — particularly loud, high-frequency, or low-frequency signals — can damage hearing and audio equipment if played at high volume. Always start at a low level and increase gradually. You are responsible for protecting your ears, your speakers, and your headphones. We are not liable for any damage to hearing or equipment that results from using the site.

Not professional advice

TestTones is a measurement and calibration tool, not a medical device. Information on this site is for general educational purposes only and is not medical, audiological, or professional advice. A hearing-range test on this site is not a clinical hearing test — if you have concerns about your hearing, please consult a qualified audiologist or physician.

Changes

We may update these terms from time to time; the "last updated" date above reflects the latest version. Questions? Email contact@testtones.com.
