Mei Wu Acoustics

The following are typical acoustical and vibration issues associated with residential projects:

Projects > Residential Spaces

Our work on residential projects varies from recommending high quality acoustics and sound isolation for luxury residential buildings to recommending low cost construction details to meet building codes and basic acoustical requirements. The following are a few recent residential projects.

Block 2 and 1180 4th St, Mission Bay, San Francisco CA Block 2 and 1180 4th St, Mission Bay, San Francisco CA

Block 2 and 1180 4th St are ongoing residential design projects in Mission Bay San Francisco. Block 2 is 350 market rate apartment units and is in the Design Development phase, while 1180 4th St is 150 affordable units and is in Construction Documents phase. Mei Wu Acoustics is the acoustical consultant for both projects. mercy housing - 1180 4th Street San FranciscoIn the early design stages, the primary tasks have included modeling future traffic noise exposure and developing façade elements to meet building code exterior noise level requirements, as well as developing wall and floor/ceiling details to meet building code interior sound isolation requirements. MWA has also provided guidelines on room layout strategies and specification items for mechanical noise and vibration control.

Triton Plaza, Foster City, CATriton Plaza, Foster City, CA

Triton Plaza is a 300-unit mixed-use luxury rental apartment complex. It is a current MWA consulting project, nearing the end of its design phases. MWA worked very closely with the architect in the design of the building shell in Triton Plaza; it is located 150’ from CA-92 and required extensive research and discussion on different window types and z-duct design to meet building code requirements. MWA has also advised on all internal acoustics issues such as acoustical isolation of dwellings for code and MEP noise and vibration control.

Meridian Apartments, San Bruno CAMeridian Apartments, San Bruno CA

This project included the design and construction of a five-story 300-unit apartment building with a five-six story "embedded" parking structure and detached recreation and business center. The building was located near major freeways and the San Francisco International Airport. MWA was responsible for all aspects of acoustics.

Santa Clara University Residential Hall, Santa Clara CASanta Clara University Residential Hall, Santa Clara CA

This was a wood frame four-story building including housing for 260 students, five faculty members, and a common area with classrooms and seminar rooms. MWA was responsible for all aspects of acoustics.

330 & 335 Berry Street, San Francisco, CA330 & 335 Berry Street, San Francisco, CA

This project included two new residential buildings with total 131 condominium units plus parking garages. Each podium includes a central landscaped courtyard. The building was designed to achieve the equivalent of a LEED certification. MWA was responsible for all aspects of acoustics and vibration.

Paragon Apartments, San Bruno, CAParagon Apartments, San Bruno, CA

This was a new, high density 4-story apartment building over a 2-level concrete parking garage (one of the parking levels was below grade). The building had 150,000 square feet spread across its 185 units and parking deck. MWA was responsible for all aspects of acoustics.

Acoustical Testing in Existing Residential Buildings, CA

MWA conducted ambient noise testing, sound isolation testing (STC and NIC) and impact sound testing (IIC) in many existing residential buildings, compared test results with building codes, and provided noise mitigation recommendations.

Mission Street Housing Project, San Francisco, CA

This project has over 100 rental units for fixed-income housing constructed on 13 levels. The ground floor has retail space, community space, and supportive services space. The ground level has outdoor courtyard space and a children's play area. The project requires a LEED silver rating at a minimum. MWA is responsible for all aspects of acoustics.

Tannery Arts Center Buildings 11 and 12, Santa Cruz, CA

This low-income housing project was a wood-construction, three-story buildings with a total area of 180,000 square feet. The units were artist-live-and-work lofts. MWA was responsible for all aspects of acoustics.

Sustainable Community Number One, Boise, ID

This was a 16-story 106 unit condominium building with retail and office communities, located near a busy intersection in downtown Boise. The rooftop had an outdoor shared patio/lanai barbecue space. MWA recommended a low profile floor-ceiling design to minimize building height. Interior partition alternatives were suggested for space savings and recycled materials were studied as effective solutions. Design issues included magnetic elevators, steel stairs, and low noise toilets. Many features were sustainable by design, such as photovoltaic power and garbage composting. This project was put on hold.
