CSDA Design Group was contracted as the acoustical engineer for the ground floor retail space of a new five-story, mixed-use residential and retail complex. Located in the city of Sunnyvale, CA, the Solstice Apartments consists of 280 units, studios to three-bedrooms totaling 250,000 SF and 34,000 SF of retail. Our scope included analysis and design input to reduce structure-borne and airborne noise from the sports facility to the apartments above. We also conducted on-site acoustical measurements to verify compliance with the City’s noise ordinance requirements.
