I used to play Tchaikovsky's 1812 very loud when I was in school. Living in a coed dorm, my neighbor was a girl who would play the same rap song over and over for everyone in the hallway to hear. However many times I've told her to turn the volume down she would always forget. So... all I can say is that the cannons did wonders. I would sometimes hear cheers from others in the hall when she turned off her stereo.
