The store I worked in at San Diego was going through a remodel, and they had to be a lot louder than 90dBA with their saws and other equipment. (I didn't even check if there's an app to measure dBA) They didn't offer any ear protection so me and one other guy brought our own. It didn't make me think highly of the company. If I were the store manager I would have set a box of ear plugs in the break room and let it be take as you need them. The other guy that cared about his hearing and I laughed about how they certainly didn't pay us enough to go deaf. I'm saving that for concerts and other frivolities.

The ear plugs actually pulled out a lot of wax when removed. That was rather satisfying. There was blood at some point but that's hardly the first time.
