Eight categories are refused, each with a reason; the two most expensive refusals are gear reviews and affiliate links, and both are kept deliberately.
Refuse: what this register will not write
checked 2026-09-16responsible Room Tone Register (a named register, not a person)
The list, with a reason per line
| Not written | Reason |
|---|---|
| Gear reviews and picks | A review needs comparative testing this register does not run; without it the page would be an opinion with a link in it |
| Affiliate or sponsored content | The register has no revenue relationship with any manufacturer; introducing one would change which pages exist |
| DAW and plugin tutorials | Software workflows change faster than a manual can be corrected, and the failure modes are not measurable in a room |
| Music production and mastering | A different discipline with a different evidence base; the register would be guessing |
| Legal, union or contract questions | No responsible party here can answer them |
| Hearing health advice | The register cites NIOSH, HSE and WHO; it does not diagnose or recommend protective equipment |
| Room design services | The register describes what a room does; it does not sell a design |
| Anything without an extra inch | A page that repeats what the first page of search results already says has no reason to exist |
The refusals that cost the register the most
Two of these are expensive. Refusing gear reviews removes the highest-traffic content in this subject area, and refusing affiliate links removes the obvious way to pay for the site. Both refusals are kept because the alternative is a site whose pages exist to move a purchase rather than to answer a measurement question — and readers can tell, which is precisely why the measurement pages would stop being believed.
What happens when a topic is borderline
If a topic needs a measurement the register cannot make, it is refused. If it needs a measurement the register can make but has not made yet, it is deferred, not guessed. If it needs a measurement the register has made in one room, it is published as a note with the conditions stated, and it is marked as a figure that can rot.
A refusal list is also a scope guard. Without one, every register drifts toward whatever gets traffic, and the drift is invisible until the site is a different site.

Each line points at one specific document. No line is a home page.
Leave this page Close this page if your question is on the list. The register will not answer it, and saying so is the useful part.
