Terms of use

Permitted use

You may use the tools to perform browser-based audio checks and preserve your own observations. Do not use them in a manner that could harm people, hearing or equipment.

Safety

Begin at a low device volume, stop if a signal is uncomfortable and never treat a browser level as a physical SPL reading. You remain responsible for connected equipment and listening conditions.

Limitations

Results depend on the complete browser, operating system, device, cable, interface, room and transducer path. They are not certification, calibration, medical diagnosis or a warranty of equipment performance.

Availability

The service may change as methods are validated and browser behavior evolves. Unsupported or unreliable measurements may be removed.
