Psychological, physical harm due to Excessive Noise?

Yay, slow news day story! According to NBC3, folks in the Tenderloin (AKA the Uptown Tenderloin Historic District) and SoMa face "psychological and physical" harm due to noise pollution. The San Francisco Public Health Department says that the urban sounds filling city streets (i.e., traffic) can cause high blood pressure, heart disease, depression, and digestion problems. Yikes. SF is currently looking at measures to reduce traffic,the main cause of said loudness. (NBC3)
