What we do

Acoustics, noise and vibration under one roof, from first feasibility study through approval, construction and verification.

Building acoustics

Architectural acoustics and room design.

Reverberation, speech intelligibility and finishes, from lobbies to lecture halls.

Sound isolation design.

Partitions, floors and envelopes designed to meet OBC and the criteria above it.

Mechanical noise control.

HVAC, generators and equipment, from selection through commissioning.

Acoustic testing and commissioning.

Field testing to ASTM and ISO, and verification that the design performed.

Tarion RB19 acoustic review and testing.

Design certification, shop drawing and field review, and field testing for Type C and D condominium projects under Registrar Bulletin 19.

Secure spaces and speech security.

Sensitive discussion areas, secure offices and briefing rooms, from envelope and door design through Speech Privacy Class testing to ASTM E2638.

Environmental noise

Environmental noise assessments (ECA and EASR).

Acoustic Assessment Reports and compliance under MECP publications.

Noise impact studies.

Predicted sound levels at receptors from a proposed or expanded facility.

Noise feasibility studies.

Land use planning studies for development approvals.

Transportation noise studies.

Road, rail and transit noise for sites near corridors, and for new and expanded transportation infrastructure, with the rail vibration assessment that usually goes with it.

Aircraft noise and NEF contours.

Noise Exposure Forecast contour development for airport operators, and assessment of development on land the contours affect.

Noise control design.

Silencers, enclosures, barriers and layout changes to bring a facility within limits.

Acoustic audits.

Measurement of an operating facility against its approval conditions and applicable limits, including the annual audits required at pit and quarry operations.

Noise Abatement Action Plans (NAAP).

Sequenced, costed abatement programs for facilities that cannot demonstrate compliance, with the acoustic audits that verify them.

Noise by-law compliance and complaints.

Investigation, measurement and resolution when a complaint has been filed.

Vibration

Rail and transit vibration.

Ground-borne vibration and ground-borne noise for sites beside GO, subway, light rail and freight corridors, assessed against the Metrolinx Adjacent Development Guidelines and the criteria the corridor owner applies, with setback and isolation where a site needs it.

Construction vibration assessment.

Predicted levels at neighbouring buildings, heritage structures and buried services from piling, shoring, excavation and compaction, with limits set before the work starts.

Blast vibration and overpressure.

Limits, prediction and compliance for quarry and construction blasting.

Building vibration control.

Footfall, structural response and isolation design.

Vibration-sensitive equipment and facilities.

Imaging, microscopy and metrology, designed to the equipment’s own criteria.

Monitoring

Noise monitoring.

Short and long-term monitoring for construction, compliance and complaints.

Vibration monitoring.

Continuous monitoring with alarm thresholds for work beside occupied buildings.

Advisory

Owner’s advisory and compliance review.

Acoustic output specifications, design and construction compliance review, and technical advice on the owner’s side of a P3 or alternative delivery project.

Peer review and expert witness.

Independent review, and expert evidence at the Ontario Land Tribunal, planning hearings, municipal proceedings and in litigation.
