Building acoustics embraces the design of indoor environments to achieve acceptable levels of privacy, communication, and comfort for the building occupants. Acoustical performance involves room shaping, reverberation control and the location and separation of spaces. Noise control concerns may encompass the design of the building envelope, the placement and isolation of mechanical spaces and the design and control of ventilation, exhaust and air conditioning systems. Vibration issues include the control of walker-induced vibration and vibration isolation of major mechanical systems.

California Institute of Technology
The Chen Neuroscience Research Building is a Gold LEED certified facility that supports vibration and noise sensitive spaces including laboratory spaces and a large lecture hall. The building is three stories tall and includes two basement levels. We provided acoustical input regarding partitions for behavioral suites with stringent STC requirements as well as architectural acoustics support for offices, conference rooms and the lecture hall. Additionally, we provided support for vibration control via the structural and mechanical design for the vivarium and research labs. A site survey was conducted to confirm that the area was not problematic with regards to vibration and noise. Additionally, measurements were taken to verify that the construction of CNRB did not negatively affect nearby sensitive spaces on campus.
The Whiting-Turner Contracting Company / Johns Hopkins University
The Materials Characterization and Processing core facility is maintained by the Department of Materials Science and Engineering at Johns Hopkins University. The MCP serves the entire Johns Hopkins community, with focus on inorganic characterization and processing. Our vibration surveys for both post-demolition, and post-construction of the lower level labs were consistent with results prior to the start of the project.

A renovation of the existing Peterson Hall 2, the center is dedicated to increasing services for CSULB’s tens of thousands of students. The facility serves as the new to the Bob Murphy Access Center, formerly known as Disabled Student Services. The Student Success Center also houses programs such as BUILD, which supports undergraduate research in the health sciences, and the Women’s Gender & Equity Center.
University of Chicago
This multifaceted research center is home to the Institute for Molecular Engineering, Department of Astronomy and Astrophysics, the Kavli Institute for Cosmological Physics, the Dean’s Office of Physical Sciences, and the Pritzker Nanofabrication Facility.
University of Michigan
This new facility houses The Center of Excellence in Nano Mechanical Science and Engineering, and includes a state-of-the-art Ultra-Low Vibration Facility. The unique and innovative vibration and noise control design for the ULV facility resulted in some of the lowest vibration amplitudes we've ever measured.
