Noise = Stroke for Elderly?

For people over 65, research finds a 27% increase for risk of stroke for every 10-decibel increase in street noise.

Researchers studied 51,000+ Danish city dwellers for ~10 years. The study, however, doesn't categorically prove road noise causes strokes. But studies have linked noise to heart attacks and higher blood pressure — possibly because of increased stress and less sleep.
