Abstract:

Sounds associated with oversnow vehicles, such as snowmobiles and snowcoaches, are an important management concern at Yellowstone and Grand Teton National Parks. The John A. Volpe National Transportation Systems Center’s Environmental Measurement and Modeling Division (Volpe Center) is supporting the National Park Service (NPS) with its on-going Winter Use Plan (WUP) program. As part of this support, acoustic measurements of twenty-five snowcoaches were made at three locations in Yellowstone National Park in January 2009. Measurement methodologies were guided by SAE J1161 with recommended improvements from 2008 measurements also performed for NPS by the Volpe Center. Data collected will be used to 1) refine and finalize snowcoach sound level testing procedures recommended from the 2008 Volpe Study, 2) determine which snowcoaches have the Best Available Technology (BAT) with respect to noise emissions, 3) determine any site-specific measurement bias, 4) develop a sound level versus speed relationship to determine if any measures could be taken for vehicles exceeding BAT requirements, and 5) develop OSV noise-distance relationships for use in a modified version of Federal Aviation Administration’s (FAA) Integrated Noise Model (INM) developed for NPS in a previous study.
