What We Do

Acoustic Treatment

There are two critical factors that are required during every meeting, lecture, or conversation – being understood and understanding what is being said; whether on a video conference call or an in-person meeting.

The often forgotten factor during video conference calls is that the conversation is between two different spaces that will have different acoustic properties.

Nothing does more to stop the flow of conversation than poor sound quality. (reword)

Our Solutions 

Room Acoustics

Architectural and design trends of hard surface rooms can lead to poor acoustics and speech intelligibility – known as the ‘Fishbowl’ effect.

We concentrate on optimizing Room Acoustics with specialty materials, transparent sound absorbers and camouflage solutions.

Isolation Acoustics

We provide solutions which keeps private information from your meetings in the room.

  • Protection of private conversations
  • Containing amplified voice and A/V information in meetings
  • Isolation optimization through sound barriers and room ‘tightening’

DeAmp Panel

The only truly transparent sound absorber. 

DeAmp Transparent Sound Absorbers are the solution to controlling the acoustics in rooms with large areas of glass or other hard surfaces – while maintaining transparency and openness.

Customizable options for DeAmp panels include:

  • High resolution CMYK colour printing
  • 3M™ and SOLYX® film application 
  • Options include coloured, matte, non-glare, frosted P95, and ‘sign white’ acrylics
  • Back lighting options

Diffusers, Scatterer & Redirecter

Diffusion, scattering, and redirection products control reflections without making the space sound too acoustically “dead”. 

Typically constructed with Class “A” fire-rated wood or thermoplastics. 

  • Available with an infinite range of veneers and stains
  • Available as a painted surface or as Pantone/RAL colour
  • Mounting options are typically on the wall or ceilings
  • Quadratic Residue Diffusers are sequence 11 with Schroeder low frequency cut offs 

 

Fabric Wrapped Panels & Stretch Fabric Walls

Fabric wrapped panels are the most common form of acoustic treatment. For large area coverage, stretch fabric walls are a great option for “hidden acoustics”.

Custom options are:

  • Hundreds of fabric options to match your decor.
  • A range of thicknesses to absorb at different frequency bands.
  • Constructed of only fire-rated fabric and substrate.
  • Multiple mounting options are available for fabric wrapped panels.
  • Customizable options for stretch fabric walls.

Eco-Felt Absorbers

An eco-friendly option for acoustic absorption. Made from 100% polyester fibre of which 60% is derived from recycled water bottles.

Which contributes to LEED MR credits. 

Fire testing – Class A E84 and ULC S102.

 

Custom options are:

  • Available in 20 colours and two thicknesses.
  • Infinite design options – such as wall & ceiling panels, hanging canopies, and acoustical privacy barriers.
  • Computer-controlled cutting to any shape imaginable.
  • Impact, bacteria, and moisture resistant.
  • Tackable, lightweight with no VOCs.

Frequently Asked Questions About Acoustics

Q: Where can acoustic treatments be implemented? Is it only in new buildings?

A: This answer can be broken down into two sections – isolation and room acoustic treatments.

Isolation acoustic treatments

  • Should be accounted for during the design and planning stage of either renovation or new build projects.
  • This type of treatment is most often a material or design that will be incorporated into the wall, ceiling or entrance door assemblies that make up the room(s).
  • No matter the level of acoustic isolation that is required between adjoining spaces, the materials can easily be designed and built into the assemblies so they will be completely unseen.
  • Adding these materials after the walls, ceiling and entrance doors are already built and installed will present a challenge.  It can be done however it is typically more costly and typically will not perform to the same level of efficiency.

Room acoustic treatments

  • The limiting factor for this type of acoustic treatment is usually the client’s, Interior Designer’s or space planner’s aesthetic design.  We recommend that the room acoustic design is planned for at the same time as the finish design is being considered.
  • The use of all hard-surface materials in a space will greatly impact the room acoustics.
  • If the floor is hard, if there is an exterior half-wall of glazing, if there is an interior hallway wall full-height glass partition, if there is a drywall ceiling – these all hard surfaces will result in a considerable amount of reverberation in the room.
  • If all the walls are parallel with no or very limited design geometry – this will result in a build-up of reverberation in the room.
  • To address the hard surface reflections ‘some amount’ of absorptive material must be installed on these surfaces. The primary goal is to integrate these treatments into the decorative details of the design and room aesthetic without significantly changing the design intent.
Q: How much of the space do you treat?

A: The amount of space that needs to be treated is difficult to assess without seeing the space. The below factors will dictate the amount and type of treatment to be used.

  • How big is the room?
  • Does the room have high ceilings?
  • What is the rooms cubic volume?
  • What is the shape of the room?
  • Is it round?
  • What materials make up the walls, floor and ceiling surfaces?
  • What is the intended use of the room?
Q: How do you know that a space needs acoustic treatment?

A: There are both subjective observations and empirical testing that can be used to judge how ‘correct’ the acoustics are in a space:

  1. How we judge the “rightness or fittingness” of a room’s acoustics can be precisely designed and measured.
  2. However, most people do not become consciously aware of this room characteristic until the room has been built.
  • A simple subjective assessment of the room plans before the room is built will reveal if there will be a future problem.
  1. Are the surfaces in the room 50% or more hard surfaces?  If the answer is yes – there will be acoustic problems.
  2. If a room sounds even a little like what you experience in a fire-escape stair-well or parking garage – this is a problem.
  3. If a room has loud ambient (background) noise – this is a problem.
  4. Can you clearly hear when the HVAC system turns on/off?
  5. Is external noise – from other rooms, hallways or from the outside world – clearly heard in the room?
  • We also offer testing (with instrumentation) of spaces pre-installation of acoustic treatment – to clearly document the existing base-line acoustic problems.  These tests are conducted to ASTM or ISO international standards and so are not subjective but empirical.
  • After installation of the specified acoustic treatment(s?), re-testing of the space is also offered to gauge performance and to what extent the problems have been addressed. We recommend that three tests are conducted in most spaces.
  1. Background Noise
  2. Reverberation Time
  3. Speech Transmission Index
