nope..don't buy it. you'd be more likely to suffer hearing loss from operating power tools, the lawn mower, playing the radio too loud (especially in the car), etc. noise is the common cause of high frequency hearing loss. damage is caused when you are subjected to noise over 130db., and most concerts we attend are direct assaults on your hearing. anytime your ears ring..there could be damage. now...maybe there's something to that study, but believe me...everyday noise is going to harm you (and most of that you can't control) more than a cell phone.
