Does OSHA require companies to divide the Noise Reduction Rating (NRR or NRR-7) in half?
When it comes to assessing feasibility of engineering noise controls, OSHA requires that employers estimate real-world hearing protector performance by "de-rating" NRRs by 50%. However, when it comes to complying with hearing conservation program requirements, OSHA does not require de-rating the NRR (or NRR - 7 for A-scale noise measurements).
