Many people listen to music on MP3 players while in the library. This is cool. But when listening to music in a confined space, ask yourself this:
1) Have several people given me the stink eye?
2) Are people moving away from me, giving me enough room to perform an impromptu flamenco dance?
3) Are my ears bleeding?
If you answered yes to any of these questions, your personal music may be leaking loudly into a very public space. Most offenders seem surprised that their music is loud enough to be heard by others, so if in doubt, try this: while at your preferred volume, remove your earbuds and with your fingers, cover the part that should be in your ears. Can you still hear any sound? If so, your music is loud enough to disturb others.
Please be considerate of this shared study and work space.
