Acoustics, Noise & Vibration
Maximizing occupant safety and comfort in all types of structures – new and old – and tuning listening spaces for optimal acoustics.
Whatever your project, controlling noise and vibration can be critical to success. Perfecting the acoustics in a concert hall. Making it easier for students to concentrate in class. Limiting uncomfortable sway in tall buildings. Protecting industrial workers from hearing loss. Keeping sensitive medical imaging equipment rock steady. Complying with national or local regulations. Preventing your construction activity from damaging nearby structures. We have the expertise you need for all these and more.
We’re also adept at analyzing, testing, documenting and remediating unwanted noise and vibration in existing structures. And we can provide compelling expert witness testimony if necessary.
We apply tried-and-true techniques and innovative methods to a full spectrum of architectural and forensic acoustics services.
Architectural acoustics, noise and vibration. Analysis and design to control and balance competing acoustic, noise and vibration requirements for new buildings and renovations.
Construction vibration assessment and monitoring. We assess, monitor and mitigate construction vibration levels in jurisdictions that require vibration-control plans. This includes considerable expertise with Toronto's By-Law 514-2008 which requires an assessment of the zone of influence of construction vibration in support of building and demolition permit applications to minimize the adverse effects on adjacent buildings and structures.
Aeroacoustics. We perform wind-induced noise risk assessment and remediation. Wind flow over architectural features such as façades and railings can cause significant whistling or humming. We analyze the geometry of these features, as well as the local wind environment, to control or eliminate wind-induced noise.
Footfall-Induced Vibration. We use advanced analytical tools – including FootPrint, our own proprietary software – to predict and mitigate the effects of footfall-induced vibration, one of the hardest-to-predict sources of disruptive movement in buildings.
Vibration testing, monitoring and control. We measure and analyze the structural vibration profiles of sources that could affect your project, from roads and subways to HVAC equipment, human activity and wind.
Tuned mass dampers (TMDs). We design – and verify the effectiveness of – solid and liquid TMDs for floors, long-span structures, bridges and towers. We’ve also invented a new kind of TMD.
Environmental noise and vibration control. We help you stay on the right side of regulations with noise and vibration assessments, noise-impact statements and design for noise-reduction measures. With decades of experience, we’re well-versed in the requirements of jurisdictions across Canada and the United States.
Forensic noise and vibration testing. Dealing with unwanted or objectionable noise? We quantify it, find its source and recommend fixes. Need a specialized monitoring system? We can do that too.
Expert witness testimony. Our seasoned and well-respected experts can clearly communicate salient information on the material and psychological aspects of acoustics, noise and vibration.
Acoustics, noise and vibration control education. We offer courses that are accredited with architectural governance bodies in Canada and the United States.
We maintain laboratory-quality instrumentation for sound and vibration measurement, recording and analysis. Our experts use industry-leading products for environmental noise analysis, room acoustics prediction (ray tracing), system analysis and computational analysis.
