These two sites are super cool for checking how much hearing you've lost from all of those loud concerts and 'cranking up the volume' on the headphones and jamming out in your car. It's added up and you're deafer than you thought! Check both ears - one may hear better than the other. BTW, this is the same test that they give kids in school each year to check their hearing - adults can usually only hear up to 15 kHz but kids can usually hear up to 20 kHz or higher.
