Why would hearing muffs be tested against continuous and not impulse noise?
Looking at a new pair of earmuffs that a NRR (Noise Reduction Rating) or 34 DB. However the fine print says that said rating is for continous noise and not impulse (like gunfire). Why would they be tested that way as a big reason people buy earmuffs is to protect their hearing while shooting?
