This launch guide maps the topic, the source base and the practical questions. Check the linked official authority before acting on a rule, deadline, price or safety requirement.
What this guide covers
The dose page is the point: 80 dB for 40 hours a week, converted into what a phone's volume slider actually delivers, so "how loud is too loud" becomes a number of hours rather than a warning.
Item pages cover the EU volume-limit rule and why "100% is fine" is wrong, the safe-listening standard and the features it asks manufacturers for, children's volume-limited headphones as measured in published tests, how noise cancelling lets people listen quieter, isolation against ANC against open, bone conduction and road awareness, in-ear hygiene, wired against Bluetooth codecs, impedance, and measurement graphs explained. ~14 pages.
How to use it
Use Headphones and safe listening to understand the inputs, units and assumptions before relying on an output. A useful result should be reproducible from the named source rather than presented as an unexplained score.
The page keeps the main question, its evidence base and its limits together in one canonical place. That makes it useful as a quick orientation and avoids splitting a broad subject into shallow pages before each narrower answer has enough verified material of its own.

Evidence and provenance
The evidence map below records the primary, official or openly licensed material chosen for this guide. It is deliberately visible so a reader can tell the difference between a rule published by an authority, a measured dataset and an editorial explanation.
Source: ITU-T H.870 safe listening standard (ITU, free), EN 50332 scope abstract, WHO Make Listening Safe materials (free), NIOSH noise dose tables (public domain), published measurements of children's headphones (cited); dose table computed. · checked 2026-09-09
Source names are preserved even where an authority changes its web address. No figure is added to this launch page unless it is already present in the cited source description or can be computed from a named dataset.
