The issue with these kinds of test is people dont like taking them and this undermines the effort involved in creating it.

Its a shame as gathering data like this could be brilliant. Iv noticed @Blumlein 88 has made several similar efforts with uptake limited.
Downer and eventually you kinda think why bother. Still maybe when this site a little more mature we can put something 'official ' up and really try to drive participation.
Well, the thread was created two years ago and only resurrected today and the links are long dead. Can't blame people for not participating now...

Okay at least some simple mono files. White noise which was at the labeled levels of minus 30, 50, 60, 70, 80, and 90 dbFS. After filtering at 6db per octave below 3 khz and 12 db per octave above 5 khz the RMS level is down some 11 db for the entire audible bandwidth. Files are in 16 bit FLAC once you open the attached zip file. TPDF dither was used. You get 2 seconds of noise followed by 2 seconds of silence for 16 seconds.
Remember the point is to play some music at your normal listening level. Then play these files without altering volume. The idea is our hearing is most sensitive at 3-5 khz, so if you determine where you no longer hear the noise you should be even further from hearing it at all other frequencies. Also that most people's listening rooms may not be too far above 0 dbSPL in this frequency range. Most ambient noise is lower in frequency.
John, feel free to try the tests from my above post, seem pretty OK to me. Also, check the https://www.audiosciencereview.com/forum/index.php?attachments/noise-test-zip.18957/ just posted above too.Well, the thread was created two years ago and only resurrected today and the links are long dead.

At a loud listening level, but below where it sometimes goes up to, I can just hear the -80db at the listening position. I'll try again in an evening when it's quieter, it wasn't quiet outside right now. The noise floor in my listening room get's below 0db for some of the spectrum when it's quiet.Okay at least some simple mono files.

Did your threshold change between when listening loud and flipping the switch, and using the same settings when not having been listening to music?When playing loud in my listening room I heard nothing when it was set at 70dB attenuation (or more).

Yes, that's what I was asking, for the following reason....I don't recall listening/testing and keeping it at -70dB then, after an hour or so returning and maybe then able to hear the -70dB.
That's what I think your question is about ?
A nice demonstration is going to a loud concert and when going home you almost can't hear the traffic any more. This gradually comes back over an hour or so.
My limited tests agree with that, interestingly similar to what vinyl is capable of, by luck or design.Human hearing has a wide dynamic range but the effective 'dynamic' range (when listening to reproduced recordings) is around 70dB in my experience.
