Ok, so my school put in affect a new policy stating that headphones are no longer allowed but earbuds are because headphones are obstructive and could be a hazard if there is a fire alarm. First off I'm not even going to get started on how much I hate earbuds, but don't earbuds isolate more sound than headphones? I just need some facts I can add to a petition I'm taking to the school board. What is the decibel cancellation with in- ear earbuds vs. headphones. Which is really more hazardess? I just need some facts and maybe some links that would support this. If I am wrong please let me know, but I thought that earbuds isolate more sound than headphones because they go in the ear and form a seal inside the ear canal. Thank you P.S. I hope I put this in the right forum.
