Campus-Wide Environmental Noise Model

National Institutes of Health, Bethesda MD

We worked with NIH to develop a comprehensive detailed computer environmental noise model of their entire campus in Bethesda, MD.

We conducted sound power measurements of all major building noise sources distributed across the over 300 acre campus. Sources associated with all of the over 30 buildings on campus, as well as the central utility buildings and other support facilities were documented.  Multiple surveys were conducted at different times of year to document the change in operating points of the various noise sources.
This data was utilized to construct a comprehensive computer noise model of the site, showing the propagation of noise across the campus and the impact on adjacent properties.  The noise model was calibrated using detailed noise monitoring results conducted along the campus property line.

The full model was delivered to NIH to be incorporated into their campus GIS system, and to be used to evaluate the impact of current and future noise sources.
