CSDA worked with the design team to provide acoustical consulting services for conversion of an industrial building into audio technology office space. We provided design input on room acoustics, sound isolation, and noise and vibration control for secure workrooms, electrical and server rooms, large and small offices, meeting rooms, shipping/plot room and kitchen.
CSDA was retained to provide acoustical consulting services to provide design input on a digital and metal lab spaces to reduce noise and vibration from the machines/equipment into the adjacent office spaces.
CSDA is working with the design team to provide acoustical consulting for a confidential client’s advanced technologies office space in Mountain View, CA. We provided analysis of noise and vibration from machinery to adjacent offices, along with providing design input on sound isolation, room acoustics and HVAC noise/vibration reduction.
Phase I – As a consultant, the team led by Freytag & Associates, performed an airplane noise assessment for the District of Columbia focused on noise impacts from changes to flight paths made out Ronald Reagan Washington National Airport (DCA). There were two major parts to the project. The first consisted of a thorough review and documentation of existing data supplemented by new investigations to document the past and current airplane noise environment over the D.C. area. Second, the team worked to develop revised air traffic procedures, acceptable to the FAA, to minimize the current noise impact over the affected areas in D.C. The overall purpose of the project was to determine what, if any, noise impacts have occurred in the District as a result of the FAA’s implementation of NextGen air traffic control procedures and routes. Finally, we identified potential flight path/route changes and other airspace modifications to reduce flyover noise in the District.
Phase II – This phase builds on the previous Phase I study. Utilizing the measurement data collected in Phase I, the consultant team will compute various supplemental noise metrics (Lmax, Leq, Time Above Level, etc.) identified by the U.S. Department of Defense (DOD) Noise Working Group to further quantify noise impacts and changes in aircraft noise due to arrivals and departures at Ronald Reagan Washington National Airport (DCA). Additional long term field measurements will also be conducted. Specifically, the results of the analysis will compute the change in noise exposure due to airspace modifications made from the Next Generation Air Transportation System (NextGen) initiative. The consultant team will also quantify the community impacts (e.g., sleep disturbance, speech interference) according to national standards. Additionally, we will identify and encourage improvements and changes to existing noise abatement procedures and practices to reduce aircraft noise impact over the District. Specific noise mitigation recommendations will be developed for presentation to airport management, the Metropolitan Washington Airport Authority (MWAA), and to the Federal Aviation Administration (FAA). The primary beneficiary of this project will be the District residents, as the goal of the project is to reduce DCA aircraft noise impacts and improve residents’ quality of life through aircraft noise reduction. The estimated date for this project is by September 2018.
CSDA is providing acoustical consulting services for the adaptive reuse of 6 buildings for confidential tech client located in Mountain View, CA. The office buildings contain offices, meeting rooms, phone rooms, research and development spaces, and industrial spaces. We are providing recommendations for sound insulation, room acoustics, and HVAC noise. Additional inputs will be provided for structure borne noise and vibration transmission from the research and development spaces.
