Noise Kills

A study reports that chronic exposure to noise increases the chance of heart attacks. Oddly enough the average noise level of a typical busy large office, 60db, is about the threshold that researchers have found for an increased risk of heart attack. Even more oddly, they've found that noise in the workplace doesn't effect women. This doesn't seem right. Why would the type of noise matter? whether it's a jet plane or xerox machine, noise is noise. and why would it matter between the sexes?

I hate these kind of articles where they just present these weird findings without even a theory for the reasons. In Harper's magazine on the back page it's funny, but in general I want more sense made from the datasmog being pumped at me.
