Occupational hearing guidelines permit hearing loss rather than prevent it

Evidence

Applying occupational hearing conservation guidelines (OSHA and the like) does not prevent hearing loss. Their goal is to preserve enough hearing at the end of a career to be able to carry on a (flawed) conversation at a distance of 1 m. These are guidelines created for factory workers, not audio engineers. — , Toole, Floyd E - Sound reproduction-…, 1249 (#corroborates, via linked claim)
