CSDA was hired to provide acoustical design services for an apartment building located at 570 21st Street, Oakland, California. The project consists of a podium level (Type I) with four levels of Type III construction on top. Our services include measurements and analysis of environmental noise intrusion, calculation of required window and exterior door STC ratings. We also provided architectural acoustics input for sound isolation (e.g., party walls, floor-ceiling assemblies), along with mechanical noise/vibration control.


CSDA was retained to provide acoustical consulting services for this mixed-use project located along busy Telegraph Avenue in Oakland. The project consists of a 97-unit apartment building with Type V wood frame construction over a Type I podium. We provided an environmental noise study, along with architectural acoustics input for demising assemblies such as party walls and floor-ceiling assemblies. An analysis of HVAC and mechanical noise/vibration is also being conducted.


CSDA conducted an environmental noise study for the planned construction of a new, three story commercial building in downtown San Mateo. We measured and compared existing environmental noise levels to acoustical criteria in the State Building Code and the City of San Mateo’s General Plan. CSDA’s report included noise reduction measures, such as sound-rated windows and doors, for the mixed-use retail and office space.

Acousticians reviewed the mechanical drawings and provided multiple options to reconfigure or modify the mechanical equipment to meet the noise criteria in the City of San Mateo’s Municipal Code. In addition, CSDA provided HVAC noise/vibration reduction recommendations for the office spaces.



Kiddie Academy Childcare relied on CSDA to prepare an environmental noise study for their new location in San Jose, CA. Acousticians measured and calculated the existing environmental noise exposure at the site and evaluated interior noise levels inside the daycare center. As part of the study, CSDA calculated the expected noise generated by the children on the playground to neighboring residences to determine if a noise variance from the City was necessary to meet the San Jose Zoning Ordinance. We recommended mitigation measures, such as sound-rated windows and doors, to reduce noise generated by traffic on Almaden Expressway, and to meet CalGreen and City requirements.


CSDA conducted an environmental noise study for the planned Presidio Knolls School campus expansion in San Francisco, California. The project will replace existing campus buildings with new classroom buildings and a music building. CSDA identified noise reduction measures needed for the new proposed buildings to meet City of San Francisco and State of California noise criteria.
