Report a measurement issue

Include the page URL, device model, operating system, browser and version, microphone used, and what you observed. If you compared the result with another meter, identify that meter and describe the distance and placement of both devices. Do not attach an audio recording unless it is specifically requested.

Request a factual correction

Identify the exact statement, the page where it appears, and a reliable source supporting the correction. Primary material from a standards body, public agency, or original publisher is preferred over an unsourced summary.

Privacy or accessibility feedback

Describe the browser feature, assistive technology, or privacy behaviour involved and the steps that led to the problem. This helps the issue be reproduced without collecting microphone audio or sound-level readings.
