Noise abatement strategies and modeling approaches for outdoor attractions at theme parks

Recent experience in noise abatement approaches and results for a new theme park are presented. Significant contributions from different source components on roller coasters lead to different abatement strategies taken for each. Measured source data will be presented. The relative performance of abatement applied separately to the source and sound path will be discussed, as well as the effects of source directivity. Source and propagation modeling approaches are presented, including how a customized version of a recently developed national noise model for highway traffic was applied for roller coasters and other sources.
