A city is a noisy place. The Canadian Hearing Society in … Canada… (bet you couldn’t guess that one?!) has some hearing loss prevention promotional material that says that “noise levels are doubling every decade”. While this is a story that sounds alarmist and is sure to grab attention, there are some data to support it. Noise levels do change very gradually

New Orleans, Blues, and Politics- part 1
