I’ll preface it by saying I think PA has always been too loud, but…bringing up osha is miss using the purpose of the permissible exposure limit of 90db. For work places OSHA allows a worker to be exposed to 90db for an 8 hour time waited avg. for 40 hour week WITHOUT the use of hearing protection. At 100db for 2 hours, 105db for 1 hr. Those levels are when hearing protection is required by employers. It’s not meant to set volume levels for football games and concerts where you knowingly and voluntarily submit yourself. If it’s too loud for you at any given volume wear hearing protection.
