The Hyatt Regency San Francisco Airport is a nine-story hotel located in Burlingame, California. The close proximity to the San Francisco Airport and events held in the beautiful atrium located at the center of the property created a need for sound attenuation. Acoustical panels were installed on the atrium side in addition to a secondary glazing unit on 785 guest rooms. This window reduces the sound levels in the guest rooms by 15 decibels, resulting in improved guest comfort levels. The hotel is now able to host more events in the atrium space.
