Our team brings extensive experience, deep skill sets, and a holistic approach in developing a spectrum of comprehensive architectural acoustic, noise control engineering, and environmental acoustical solutions. Our experience is supported with specialized training, and advanced degrees in both architectural and engineering acoustics.

Our forward-thinking approach to design fosters highly-effective solutions to noise and vibration issues utilizing state-of-the-art equipment and software. And we are skilled at developing effective solutions within your budget.

Mission Statement

We believe that all people deserve respect and care in all aspects of their life, including the way their world sounds. We value the complex nature of sound in our experiences, which is integral to communication, relaxation, and our understanding of the world.

Mohamed Ait Allaoua


With a diverse education and varied project experience, Mohamed brings 20+ years of acoustical design experience — and a fresh approach to problem-solving.

He is a member of the Association for Learning Environments (A4LE — formerly known as CEFPI).

Mohamed’s close work with the team allows integration of cost-effective acoustical solutions early in the design process to maximize savings for our clients.

A die-hard soccer fan, Mohamed spends time away from the office on a local pitch playing for one of his soccer teams, or catching up his favorite professional team (Leicester City). He reserves most of his soccer accolades for his own budding soccer stars — his children Kahina and Mokrane.

John Davenport

Acoustical Consultant

John is educated and trained in environmental, architectural, and engineering acoustics.

He excels at solving complex environmental noise problems,
developing noise control solutions utilizing computer modeling and acoustical field testing.

When not in the office, he can be found hiking or tinkering with drum machines and synthesizers.

Stephen Johnson

Acoustical Staff Engineer

Stephen has been working with sound and music all his life (when he disassembled some of the hammer and key mechanisms of his piano, he started thinking about engineering). He holds a Bachelor’s degree in Mechanical Engineering from the University of British Columbia, and a Master’s degree in Composition from McGill University.

Stephen is a former music teacher and trained classical pianist. He focuses on providing accessible, clear and effective acoustic solutions, and will ensure you understand the “why” the same way he has over the years for his piano students.

Projects have introduced him to interesting people, unusual places, and adventures unique to acoustics. On off-hours, he may be found getting out and about in Seattle and British Columbia, trying craft beers and cheeses, as well as thumping on a piano.

Craig Harris


Craig brings a versatile skill set to the A3 team. While his education was focused in noise control, environmental noise and architectural acoustics, his previous work experience includes room acoustics 3D modeling and sound system design for private theaters. He has been with the company for over a year and has worked on variety of projects, and likes to be challenged. Outside of work, Craig spends his time running, biking, baking, and playing with his cat.

Carter Howard


With a background in acoustics, live sound engineering, and music, Carter brings practical experiential knowledge to projects where a high signal-to-noise ratio is critical.  He has a B.S. in Acoustics, an in-depth understanding of acoustical theory, noise & vibration control methods, and a passion for high-quality sound.  Carter brings fresh eyes to each project he works on, looking for solutions to meet any specific needs of the project.

Carter has practical experience in various types of acoustic analysis including 3D computer modeling techniques for both interior acoustics and exterior environmental noise, which provide acoustic simulations and demonstrations to aid clients in the decision-making process.

During his off hours Carter enjoys venturing into the vast wilds the pacific northwest.  An avid rock climber, he is always trying to find the best views atop the mountains.
