Actions and mathematical modeling that will bring noise levels from a racetrack or raceway to a level the community will accept

Historically, new and existing racetracks and raceways encounter conflict between owners, racecar drivers, and the surrounding community. Racecar drivers enjoy the thrill of a raceway, but neighboring residents often complain about the noise negatively impacting the quiet enjoyment of their homes. This is true even when the homes are near a major highway or road. Raceways and neighboring communities are attempting to find workable solutions without compromise to the safety and enjoyment of the raceway. The presentation discusses objective information used to assist communities or town boards, nearby neighbors, and track owners to engage in productive dialogue of the outcome of the possible solution sets. Multiple solution sets are discussed which are typically acceptable to all parties, including various barriers and other innovative noise mitigation plans. The mathematical modeling and analysis of the topography around the track is presented to show how the local terrain can be used to help to achieve the required level of track noise reduction. The information will be presented through the lenses of three case studies. Two studies demonstrate solutions for specific raceways. The other case study is used to further emphasize the importance of incorporating the local terrain into the solution set.
