TRB will conduct a webinar on Tuesday, September 25, 2018, from 1:00 PM to 2:30 PM ET that features research from the National Cooperative Highway Research Program (NCHRP)’s Research Report 882: How Weather Affects the Noise You Hear from Highways.

This webinar will discuss how meteorology affects the sound adjacent to highways. Presenters will describe the quantitative research and the results of the report. They will also discuss public outreach materials that state highway agencies can use to screen for meteorological influences and explain the effects to the public.

Some registrants will need to pay $95 to attend this webinar.  Sign into to view registration information.

Learning Objectives

At the end of this webinar, participants will be able to:

  • Describe how meteorology, primarily vertical changes in temperature and wind, increases or decreases sound levels adjacent to roadways
  • Evaluate the implications for noise barrier effectiveness
  • Describe how state highway agencies can use the results of this research, including specific tools, to effectively explain those effects to the public
