Depending on where the best photos are
I'm a wedding photographer, and the DJ music at receptions can be obnoxiously (and ear damaging) loud!  Depending on where the best photos are, I often find myself standing in front of a huge speakers trying to get the shot.  Needless to say, without ear protection I know I would be doing serious damage to my hearing.  My assistant photographer at last night's wedding said her ears were ringing because of the high volume of the music.  Thankfully I had my Downbeats, which saved my butt... and ears.  Highly recommended.
