Apparent Impact Insulation Class
American Society for Testing and Materials
Certified consultant that specializes in architectural acoustics and how to effectively control noise and vibrations as it relates to buildings. The Acoustic Consultant analyzes the source of the unwanted noise or vibration and suggests solutions that will contribute to constructing a more soundproof building.
Scientific and technological field that seeks to understand and control the sound quality of building such as office towers, hotels, apartments and condominiums.
Noise that comes from, for example, voices, radio, television, etc. These noises are transmitted by the structures (floors or walls) or through openings in the room's inner wall and the outside shell of the building (windows, vents, etc.).
Canada Green Building Council
Crossed Laminated Timber
Canadian Construction Materials Center
Layer of cementitious products, resin or lime applied to the structural elements, intended to smooth, level, surface a support and/or embed elements (a heated floor system, for example), to which finished floor, for example ceramic tiles, a resilient floor or a parquet, glued or floated, is then applied.
Concrete surface in varying thicknesses (generally between 6" and 10") used for both structural purposes and general use in a building.
Installation of a glued floor with an acoustical membrane by applying adhesive (glue) under and over the membrane.
Field Impact Insulation Class
Field Sound Transmission Class
The cross section of all materials of a floor structure, that is to say from the ceiling of the unit below to the finished floor of the upper unit. The term "sandwich" is often used in the industry and has the same meaning.
Bandwidth of frequencies perceptible by the human ear and the threshold perceptibility. The range of sound perception varies according to the person's age, heredity and the ear abuse of intense activity, which make the ear more sensitive to sound. The hearing threshold of the human ear is 0 dB and the threshold of pain occurs at around 120 dB.
Impact Insulation Class
Noise that comes from a shock or a vibration and transmitted by vibrating through the structure, walls and floors of the building. An impact noise transmitted directly through the wall inevitably becomes an airborne noise.
Mechanical force which links the components of a material.
Leader in Energy and Environmental Design
Concrete mix of 8 megapascal (MPa) and Styrofoam, used to leveled existent concrete slabs on structures that can't support the increased weight of standard concrete.
National Wood Flooring Association
National Building Code
National Research Council of Canada
Complex sound produced by various vibrations, often diffused and not harmonic. A noise is usually disturbing and unpleasant, whether the amplitude is high or low.
Standardized noise where the acoustical energy is distributed uniformly in frequencies 125, 250, 500, 1000, 2000 and 4000 Hz.
Sheet material manufactured from thin layers or "plies" of wood veneer that are glued together with adjacent layers having their wood grain rotated up to 90 degrees to one another.
Concrete slabs, structures or building components which are cast off site, delivered and then lifted into place as required on the actual job site. Flooring slabs may have continuous circular cavities and are commonly referred to as 'core slab'.
Metal channel that reduces the transmission of vibrations while supporting gypsum boards which are effectively detaching the ceiling assembly from the structure.
Composite material provided with steel bars which combine resistance to compression of the concrete, and tensile strength of steel.
Value that represents the thermal resistance of materials (insulating value). The higher the R-value of the insulation is, the more effective it will be in preventing the transfer of thermal energy.
Sound Transmission Class
Concrete commonly used in all types of standard construction.
Pieces of dimensional lumber or metal that once assembled are used in the structural component of interior or exterior walls & partitions.
Tile Council of North America
Partial or complete blockage of the transfer of heat flow from one material to another by a product with an R factor installed between these two conductive materials.
Process by which we prevent direct contact between the rigid materials of the structure and the floor finishes which could result in the transfer, transport or even the amplification, pending the application, of sounds and mechanical vibrations, by resilient materials.
Volatile Organic Compounds
LEED Certification Expert in Quebec
A consistent sound or noise that has a relatively wide continuous range of frequencies of uniform intensity. A constant background noise which is capable of masking or drowning out other sounds.
AcoustiTECH specializes in acoustic solutions and offers the most effective solutions available for mitigating sound in multi-storey residential projects. Our partnership with Soprema & Fermacell allows us to expand our portfolio with efficient and diversified acoustic solutions. Our approach to sound-insulation is quite different than most as we ask questions about the nature of your building, your acoustic need or requirement and finally your budget. Once we have a better understanding of the big picture we simply provide "acoustical recipes" (options) which can allow you to save money, improve the sound quality of your building and/or even change the way you build. We back this up with a team of acoustic experts whom will help you reach your goals and rest easy regarding sound issues in your building. We are the reference when it comes to sound insulation of multi-storey buildings
