The Most Intriguing Noise in the World Is Your Neighbor?

A new study has determined the most annoying sound in the world is not snapping gum, it's not fingernails on a chalkboard. Researchers have tested a series of sounds on people and they monitored the test subjects for signs of agitation. The sounds of someone upstairs just doing regular things, walking, dropping something proved to be the most annoying of all. Imagine how happy downstairs neighbors everywhere are that after 29 years off Broadway's stump is finally closing.
