Atmospheric Effects on Highway Traffic Noise Propagation
Community & Cultural Concerns, Environmental Process
Research Idea Scope
Problem Statement – Studies by several research groups have shown that the atmospheric refraction and scattering effects that occur on the sound wave propagating from a highway traffic source is a source of error during prediction and measurement. It is possible for noise levels to change by as much as 10 dB or more at a receptor location due to these atmospheric effects. This is a topic that is not easily understood by the Public. Proposed Research – Develop materials to help explain atmospheric effects on highway traffic noise. Include information on why noise mitigation is not effective in addressing this phenomenon. The deliverable will be a brochure that can be distributed to the public.
