Tetra Tech’s High Performance Buildings Group offers a full range of international acoustics and vibration consulting services covering all facility types in the built environment.

Our acoustics specialists focus on all aspects of acoustics, including architectural and specialized spaces, environmental noise impact assessments, and the physical assessment of noise and vibration. We are consistently acknowledged for our use of sustainable materials in our designs.

In parallel with Tetra Tech’s other disciplines, our acoustics specialists achieve first-rate outcomes effectively and economically. To achieve sustainable designs, we minimize material and operating costs over the life of the building. We do this through early engagements; higher-order statistics; and a comprehensive, researched approach.

In the field of acoustics, Leading with Science® means high levels of expertise, innovation through research and development, and the development and application of specialized computer software. Among the advanced technologies we employ, Tetra Tech provides portable auralization that allows design teams to experience in real time how critical spaces and audio installations are expected to sound.

From offices around the world, Tetra Tech provides a uniform approach to the successful delivery of acoustic services. We have provided specialist acoustic services internationally since the mid-1990s, and our group of acoustic engineers and scientists continues to grow. We are a member firm of the Association of Australasian Acoustical Consultants (AAAC), and our professional staff participate as members of the Australian Acoustical Society and the Acoustical Society of New Zealand.
