Fort Union Trading Post National Historic Site: Acoustic monitoring report
Job JR. 2016. Fort Union Trading Post National Historic Site: Acoustic monitoring report. Natural Resource Report. NPS/NRSS/NSNS/NRR—2016/1305. National Park Service. Fort Collins, Colorado
In 2015, the Natural Sounds and Night Skies Division (NSNSD) received a request to collect baseline acoustical data at Fort Union Trading Post National Historic Site (FOUS). Between August and September 2015, one sound monitoring system was deployed for approximately 20 days. Results indicate that background sound pressure levels without human noise present (natural ambient sound level; Lnat) at FOUS001 ranged from 39.7 dBA during the daytime to 36.9 dBA at night. With human noise present (existing ambient sound level; L50), sound pressure levels were higher, ranging from 42.2 dBA during the day to 40.7 dBA at night. The goal of the study was to establish a baseline inventory of the soundscape (collection of all sound and noise sources in an area) at FOUS. This inventory will be used to establish indicators and standards of soundscape quality that will support the park and NSNSD in developing a comprehensive approach to protecting the acoustic environment through soundscape management planning. Results of this study will help the park identify major sources of noise within the park, as well as provide an understanding of the acoustic environment as a whole for use in potential future comparative studies.
