CSDA provided acoustical consulting services for the installation of the Philips Azurion 7 C20 Flex Arm Radiology equipment in the Operating Room of Marin General Hospital. The project consisted of the installation of radiology equipment on the Operating Room floor as well as equipment suspended from the ceiling of the second floor. CSDA measured and analyzed existing floor vibration levels at the Hospital and compared the measured levels to the manufacturer’s vibration velocity criteria to verify that ambient vibration from staff and patient footfall noise would not create imaging problems.


CSDA provided acoustical consulting services to Taylor Design for a new MRI facility in the Hospital. CSDA reviewed and analyzed the Air Handler/Water Chiller equipment installation locations and equipment sound data and calculated the expected noise levels from the rooftop equipment into the spaces below. Noise reduction recommendations including sketches and details were provided. Vibration isolation recommendations were made to reduce structure-borne noise transfer into the building.

CSDA also reviewed the MRI noise data and calculated MRI noise to the adjacent spaces as well as performing measurements and analysis of floor vibration with respect to the MRI manufacturers vibration criterion.


CSDA provided on-call acoustical consulting services for the Regional Connector project in Los Angeles. The Regional Connector consists of a 1.9-mile underground rail line with 3 new stations providing direct connection between Azusa and Long Beach, and between East Los Angeles and Santa Monica. The Regional Connector is expected to open in 2022. We are providing review of quarterly noise and vibration control plans as well as other on-call services.


The renovation of St. Anthony High School’s Clark Field will provide a much-needed community resource. The field and its facilities, located seven miles from the school, will provide all the athletic amenities needed with the bonus of acting as a community connection to St. Anthony High School.

The main field will accommodate bleachers for 1,200 spectators while each baseball and softball field house their own dedicated spectator seating. The site will also be home to the new athletic building, considered the “anchor” of the site, this building will house locker facilities, offices, weight rooms, storage, concessions, restrooms, and multi-purpose rooms.
