GRSM SOUND NAT

Scientists made long term measurements of sound in parks as well as urban and rural areas across the country. This information helped predict current sound levels for the entire United States. A model was developed to understand relationships between measured sound levels and variables such as climate, topography, human activity, time of day, and day of year. The resulting geospatial sound model can also estimate how places would sound naturally, without human influence. The corresponding Integration of Resource Management Applications (IRMA) NPS Data Store reference is Great Smoky Mountains National Park Natural Sound.
