From loss of sleep to loss of hearing, noise can pose a real threat. Recent studies have even identified a possible link between noise exposure and dementia. Traffic noise is a major contributor to noise pollution that fuels these negative health outcomes. Tires hitting pavement make up the majority of highway noise. Better modeling and barriers can work to mitigate this for folks living near areas with high levels of noise- and DOT practitioners are working toward such solutions for all affected.

Joining us on the podcast today is Noel Alcala, Noise and Air Quality Coordinator at the Ohio Department of Transportation. Noel also heads the AASHTO Noise Working Group, which operates under the Committee on Environment and Sustainability. The noise working group convenes state DOTs and promotes discourse on, and works in reducing traffic noise and its negative effects.
