Use the tools responsibly.

By using Frequency Test, you agree to use the audio tools at a low, comfortable level and understand their technical and medical limitations.

Effective date: August 8, 2026

Informational tools only

The site provides educational and general audio-testing utilities. It is not a medical device, clinical hearing test, audiogram, diagnosis or substitute for professional care.

Your responsibility

You control the playback hardware and system volume. Lower the volume before playback, stop if sound is uncomfortable, and do not use tones in a way that may disturb or harm other people or animals.

Results and accuracy

Results depend on browsers, operating systems, codecs, amplifiers, headphones, speakers, rooms, listening conditions and user responses. We do not guarantee that a generated frequency is reproduced accurately by your physical device.

Acceptable use

Do not use the site to create harmful sound exposure, interfere with equipment you do not own, or represent informal results as a medical or certified technical measurement.

Availability

The tools are provided on an “as available” basis. Features may change, and browser support can vary. To the extent permitted by law, no warranty is made regarding uninterrupted availability or fitness for a particular purpose.
