Environmental noise IconEnvironmental Noise & Vibration

People and the buildings in which they work and live are at the mercy of the environment.

Acentech specializes in evaluating, measuring, isolating, and mitigating the causes of environmental noise and vibration. Working across a spectrum of facilities, Acentech’s experts can promptly investigate, utilizing the most advanced field testing instrumentation and analysis technology, to execute streamlined solutions to meet regulatory requirements, address stakeholder needs, and reduce the impact on affected communities.

We consult in the areas of assessment, prediction, and mitigation of environmental noise and vibration:

  • in industrial facilities and array of facility types
  • at construction sites
  • from renewable and clean energy sources
  • from transportation-related noise from highways, railroads and airports


We maintain and use a full inventory of the latest software and noise and vibration instruments which are laboratory calibrated and traceable to the National Institute of Standards and Technology (NIST) to model, measure, evaluate and help mitigate noise.

  • Noise and vibration measurements, modeling, and data analysis
  • Site evaluations

  • Underwater noise evaluations


To improve the quality of life for its residents, the State of California established noise requirements for residential projects in 1974.  Noise requirements were incorporated when Title 24 of the California State Building Standards Code, defining the California Energy Code, was adopted.  Acoustical requirements were expanded to new commercial properties in 2010 when the CalGreen Building Code was adopted.  For over 30 years, Acentech has been helping developers, architects, and local governments navigate acoustical requirements and best practices for noise mitigation, to ensure compliance with the current Title 24 State noise requirements. 

If your project is in the development phase, or in the process of being approved by a building department, Acentech can quickly document the existing noise levels, evaluate the project’s design, and perform acoustical calculations to determine how the proposed project compares to the State requirements.  If modifications are required, Acentech can assist the project team in the development of a cost-effective approach to meet compliance.
