We at Colin Gordon Associates have the experience, knowledge, and capabilities to address any noise, vibration, or acoustical challenge. Our focus is to provide attentive, individualized service to architects, engineers, building owners, facilities managers, developers, and end-users.
We pride ourselves in our ability to analyze complex acoustical and vibration issues and translate that analysis into understandable, coordinated, and cost-effective solutions. Our staff are routinely involved in the research and development of vibration and noise control solutions and techniques, as our company philosophy emphasizes innovative designs for efficiency and design costs savings.
Steven Lank, LEED AP
VICE PRESIDENT
Steven Lank joined CGA in the spring of 2010. His consulting activities at CGA have focused upon vibration and noise measurements for high-technology facilities, structural analysis and evaluation, finite element modeling, construction vibration monitoring, HVAC noise analysis, and environmental noise modeling. He also oversees CGA's efforts in sustainable design, including LEED certification. Prior to joining Colin Gordon Associates, Steve worked as a structural designer of roof and floor systems in residential and light commercial construction projects, and as a Project Engineer on Health Sciences construction projects. His undergraduate thesis at the University of Virginia dealt with frequency analysis of guitar woods for the purpose of characterizing sound.
Stephen M. Jaeger, PE
SENIOR CONSULTANT
Stephen Jaeger has worked for CGA since 2003. He has over 30 years of experience in acoustics research, vibration/noise control, and measurements. Prior to joining CGA, Stephen worked for 15 years as an aerospace engineer for Dowty Aerospace Goucester, McDonnell Douglas, AerospaceComputing, and the NASA Ames Research Center. During his NASA tenure, he conducted research on jet engine and airframe noise, and consulted on the acoustical design of wind tunnels and advanced data acquisition techniques. At CGA, Stephen’s tasks are focused on acoustical design, noise control, vibration control, and environmental acoustics for high-technology facilities such as semiconductor fabs, university research laboratories, and healthcare facilities.
Matt Sneddon
SENIOR CONSULTANT
Matt has forty years experience conducting a broad range of acoustics and vibration research, development, and consulting activities. Much of this work has been interdisciplinary in nature, involving acoustics, signal processing, materials science, and software development, with projects ranging from small consultations to large R&D initiatives. He is equally at home managing the activities of project teams, mentoring technical staff, and working “hands-on” in direct technical roles.
Formerly a Senior Scientist with BBN, he worked on or directed approximately 200 projects over a 23 year period, and more recently at ATS Consulting, addressing transportation noise and vibration problems. Recent activities include developing improved methods for modeling elastic wave propagation through soils, and characterizing the behavior of high transmission-loss acoustic metamaterials.

Lee Gorny, PhD
CONSULTANT
Lee came to CGA in 2019 with seventeen years of experience in noise control engineering, acoustics and mechanical design. Here, he has focused on projects related to acoustical design and modeling, structural simulation using finite element analysis (FEA), and in measuring noise and vibration at industrial, commercial and high technology facilities. Prior to this, Lee worked at the National Institute of Standards and Technologies (NIST) developing a long-wavelength acoustical flowmeter (LWAF) and as an R&D engineer for SunPower Corporation, specializing in product design, simulation, integration and optimization.
Graham Freedland, PhD
CONSULTANT
Graham joined Colin Gordon Associates in January 2024. His background covers a wide range of engineering disciplines including extensive academic research in aeroacoustics, fluid dynamics and turbulence and three years of lithography focused work in the semiconductor industry. These experiences provide a unique analytical perspective, a strong sense of scientific curiosity, and a methodical and practical approach to problem solving.
At CGA, he approaches each problem holistically with the intention of researching, learning, and defining the behavior of the physical world. By applying a fundamental understanding of turbulent and geophysical flows to known acoustic and vibration relationships, it is possible to narrow the gap between random physical phenomenon and informed design and optimization.
Brent Ikei
CONSULTANT
Brent joined Colin Gordon Associates in 2025 and has expertise in acoustics, vibration, and audio engineering. He brings prior experience as an acoustic consultant, working on various types of projects such as tenant improvement, multi-family residential, and healthcare projects. At CGA, he continues to deliver acoustic and vibration guidance, accounting for project expectations and goals during design. Brent continues to expand his knowledge and expertise through vibration analysis, project management, and R+D initiatives at CGA.
Decades of Experience
Colin Gordon Associates was formed in March 1990, and provides specialized consulting services in acoustics and vibration control. The firm has grown steadily from a one-person firm to a strong organization offering services world-wide. CGA has evolved to provide a variety of services ranging from sophisticated vibration and noise control to solutions of more mundane problems that may arise.
CGA is the world leader in the design of low-vibration and low-noise environments for technological buildings, but we work extensively in many other sectors as well. On many projects, the company serves as a member of the architect/engineer design team. On others, the company acts individually and directly with the owner. On yet others, CGA provides oversight support as a peer reviewer, owner’s representative, or via monitoring services.

Colin G. Gordon
FOUNDER
Colin Gordon (1934-2005) founded the firm that bears his name in 1990 and worked in the field of acoustics research and noise and vibration for over thirty-five years. Twenty years were spent with the firm of Bolt Beranek and Newman (BBN), the firm largely responsible for developing the engineering science of acoustics between 1950 and 1970. Five years were spent with the Institute of Sound and Vibration Research (ISVR) at the University of Southampton. In his last twenty years, the microelectronics industry was a key area of focus, with the design of low-vibration facilities for the research and fabrication of integrated circuit "chips". Colin developed a strong and unique reputation in this specialized field. Colin was widely recognized within the microelectronics industry for his contributions to the understanding of the vibration and noise environments of technology buildings. He pioneered many of the now-common analytical approaches to floor design and the analysis of noise and vibration from ducting and piping. He was co-developer (with Eric Ungar) of the widely-used vibration criteria for vibration-sensitive facilities. He had mentored many of the current generation of vibration consultants in this field.
