SONOMA VALLEY HOSPITAL

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.
