Whether it’s identifying an elusive vibration source, isolating a single piece of equipment, a room, a whole building, a bridge or an entire transit system, Aercoustics provides unmatched experience and advanced technical methods for vibration monitoring, computer modeling, statistical and subjective analysis and design. Including the design of full building isolation systems and the design and installation of Tuned Mass Damper (TMD) systems.
Based on solid technical evidence and depth of experience, we offer both objective data and human perspective for assessing risks and complaints.
Here are some examples from the range of technologies, assessments, feasibility studies and mitigation plans that we offer for both existing and proposed developments in Canada and abroad.
- Simultaneous multi-channel surface & underground vibration level surveys
- Ground-borne vibration studies and predictions, and mitigation design
- Building-wide noise and vibration studies
- Assessments for rail grinding programs, rail defect repairs, wheel condition, new rail fasteners and new rail pads
- Wheel Condition Detection, statistical processing
- 16-channel monitoring systems
- Accelerometers, including high-sensitivity units
- Customized in-house MATLAB software for analysis.
- Performing arts centres and public institutions
- Research facilities
- Residential developments
- Industrial – e.g. heavy machinery, blasting
- Transportation – rail and subway lines
- Construction – e.g. vibratory hammers, pile drivers, blasting
- Human and environmental impact studies
- Structural damage studies
- Mitigation recommendations and designs
- FEA is a computerized mathematical modeling system factoring in materials, stresses, forces, mass and motion
- Modal analysis determines the vibration characteristics of a system; natural frequencies, mode shapes, etc.
- Both are extensively used by Aercoustics to model and predict vibratory response of structures
- Both methods are useful tools in assessing vibration problems and developing mitigation measures
- Per National Building Code of Canada, Section 4.1.8
- Sheet Metal and Air Conditioning Contractors’s National Association (SMACNA) guidelines
- Analysis of seismic restraint or anchorage systems
- On site inspection and quality control programs
- Response spectrum analysis
- Finite element analysis and modeling
