If you’re in a noisy environment more than once a week, there is just no reason not to have ear protection. This is your job, and not taking the minimal precautions necessary to take care of the most easily-preventable risk of your occupation is simply foolish. For as little as $5-$10 you can find sonic-filtering ear plugs that do not block out all sound, preserve sound quality, and, most importantly, save your ears. Drop notions of looking uncool or people caring, keep your hearing, and quit making excuses. Protect your ears.
