Editorial Policy
How we develop, check and maintain our sound measurement explanations, technical claims and health and safety references.
Topics and sources
We start with questions the tools and supporting pages can answer responsibly.
We choose topics that help readers use browser audio tools, understand their limits, make more consistent comparisons and find reliable context for noise and hearing safety.
For health and safety guidance, we prefer primary and authoritative sources such as WHO, CDC/NIOSH, OSHA and NIDCD. For browser behavior and audio APIs, we use MDN and official technical documentation. We link to the relevant source where it helps readers check a specific claim; the homepage also has a technical and safety source list.
We check the source’s scope, date and wording before summarizing it. Occupational limits, recommendations and general safe-listening advice are identified by their issuing organization and context rather than treated as interchangeable rules.
Claims and review
Tool behavior and educational guidance have different evidence.
What the tools do
Descriptions of a tool’s calculations, controls and data handling are checked against its current implementation and browser API documentation. We distinguish digital signal readings and approximate displayed dB estimates from calibrated sound pressure measurements. Our Methodology, Accuracy & Limitations and Validation pages explain that boundary in detail.
What outside guidance says
Health, exposure and safety information is attributed to its source and presented as general education. We simplify technical language by defining terms, keeping units, conditions and qualifications, and checking that a shorter explanation still means the same thing. We do not turn an illustrative value or recommendation into a claim that the browser tool measured exposure or established safety.
Before and after publication
We review factual statements, calculations, units, links and source context before publishing or materially revising content. We avoid unsupported medical, legal, regulatory and certification claims, including claims that a browser reading diagnoses hearing conditions or establishes workplace compliance. When the evidence is limited or device-dependent, we say so.
Updates and disclosures
Readers should be able to see what changed and why.
Corrections and updates
We revisit guidance when an authoritative source changes, a tool’s behavior changes, or a reader identifies an error. We correct inaccurate text or links and update affected explanations. Major site and tool changes appear in the Changelog; routine wording and link corrections may be made directly on the relevant page.
Commercial relationships
If we use affiliate links, sponsorships or another relationship that could affect how a recommendation is understood, we will disclose it clearly near the relevant content. Such arrangements would not change our requirement to support technical and safety claims with appropriate evidence.
