The CDR National Park Service (NPS) Geospatial Sound Monitoring Files include three measurements of all existing sound levels, natural sound levels without human sounds, and impact sound levels calculated as the difference between existing and natural sound levels. CDR provides 3-year estimates (2013-2015) of these measurements at the census tract-level for the contiguous U.S., Alaska, and Hawaii.
