At 30 we're looking at typically 5db loss over 8khz, at 40 more than 10db. Sure, we're not talking about total hearing loss, but the reduced sensitivity is going to overwhelm any real artifacts from 16/44 that one might have genuinely detected at 20.

Imagined artifacts will probably remain or might even increase though, since people typically have much higher spending power at 40. :)

Any evidence of this?

I worked in audiology for my entire 30's and tested my own hearing (biocalibration) once a week.

Never once saw a reduction in my hearing thresholds (250Hz - 8kHz)

Nor have I read any supporting documentation that agrees with a reduction of 8kHz thresholds before the age of 55.
