well since i was in the car audio industry for many many years before this, i have no hearing left. and it is a miss conception that noise from every day things will hurt you. in the research i did, in ear headphones will cause more damage than not wearing protection at all. and it is usually high pitched noises that hurt your hearing long term. low frequency noises dont impact as greatly. really low loud notes, as those from a manufactures demo vehicle will cause internal chaffing of organs and internal bleeding. ask me how i know, come on ask me
