Reply to Road Noise Makes Your Blood Pressure Rise – Literally | Study shows the sound of traffic is associated with increased risk of hypertension, calls for public health measures to reduce noise exposure by Hrmbee

Odd title. "Road noise" is typically what we call the noise that comes from your car'd being in contact with the road itself - road noise is louder on bumpier roads, more quiet on smooth roads. It also depends on how much noise-dampening ability your car's cabin has.

The sounds of traffic are different.
