Resonance Acoustics conducted an environmental noise study for Stanford’s University Hospital helipad. In order to renovate the elevator that serves the rooftop helipad at Stanford University Hospital, it was necessary to temporarily relocate the helipad to a soccer field on the University Campus. Since homeowners living adjacent to the campus voiced concerns that helicopter noise would negatively impact their quality of life, noise modeling was conducted to determine the expected helicopter noise and its impact. Using the Federal Aviation Administration’s (FAA) Integrated Noise Model (INM), graphic noise contours were produced to aid the University, City of Palo Alto and affected homeowners in understanding the expected noise impacts.
