Acoustic panels custom-built in Quebec to form a sound barrier around mechanical equipment.
A rooftop heat pump that disturbs the neighbours, a chiller too close to the offices, a complaint from the municipality: when equipment noise becomes a problem, an acoustic barrier reduces it before it reaches people.
Every Deflection sound barrier is custom-built to suit the needs of your project. Turnkey projects are our specialty: from the site visit to the installation of the acoustic panels, we take care of everything.
The Deflection sound barrier is made of acoustic panels installed between noisy equipment and the area to protect. Placed around a heat pump, chiller, fan, condenser or industrial machine, this acoustic barrier reduces noise on rooftops or at ground level, indoors and outdoors.
Each sound barrier is custom-built in Quebec. The acoustic panels can form a straight line, an L, a U or any other shape, to suit the needs of the project. Several sizes are available.

| Octave band centre (Hz) | 125 | 250 | 500 | 1K | 2K | 4K |
|---|---|---|---|---|---|---|
| Absorption coefficient | 0.98 | 1.10 | 1.06 | 0.96 | 0.95 | 0.74 |
| Transmission loss (TL) | 24 | 32 | 44 | 55 | 57 | 64 |
These terms describe the same solution: acoustic panels assembled between the noise source and the area to protect. It is also called a noise barrier. At Deflection, it is custom-built in Quebec, whatever name your specification uses.
A sound barrier can be straight, L-shaped, U-shaped or any other shape. Every barrier is custom-built to suit the needs of the project, and several sizes are available.
Yes. We visit the site to assess your needs and define the acoustic barrier that suits your project.
Yes. A compliance report is provided on request, at the start and at the end of the project.
The Deflection acoustic panel, galvanized steel with rock wool fill, has a noise reduction coefficient (NRC) of 1.0 and a sound transmission class (STC) of 43. It is available in 2 in or 4 in thickness.
A sound barrier is placed on one or more sides of the equipment. An acoustic enclosure covers the equipment completely. The choice depends on the noise level to be reached.
