I was having problems with my hearing. Things were extremely muffled. I thought i was loosing my hearing with age. Then I got a cold and my ears totally clogged. So i went to the dr's and he's like, they are completely occluded with wax so he used the peroxide/seringe method and HOLY ****! He pulls out this dime-size diameter ball of wax from each ear. They were like ear plugs! Everything was so much louder. Even someone talking to me at a normal volume made me wince because it sounded so loud. I could here things I hadn't heard in 2 years. Gross I know, but I had to share
140db for like more than 1 minute will cause permanent hearing loss. That's freaking loud.
