Acoustical measurements

Measurements :

  • ASTC, AIIC ratings (FSTC, FIIC)
  • Mechanical devices and systems
  • Environmental noise survey


  • Condos
  • Multi-dwelling buildings
  • Shops
  • Offices
  • All adjacent or superimposed premises

Noise spreads easily from one room to another when partitions or floor / ceiling assemblies are acoustically weak. ASTC (FITS) and AIIC (FIIC) acoustical measurements quantify the acoustic insulation performance of walls and floors with respect to airborne noise and impact noise. The collected results are compared against the standards and recommendations to establish their compliance. The measures also make it possible to guide the design of the soundproofing means as well as to verify the results.

Noise measurements of building mechanical equipment and systems

  • Ventilation
  • Air conditioning
  • Refrigeration
  • Electric generator

Sonar acoustical consultants evaluates the sound levels of mechanical devices and systems to determine their compliance based on applicable standards (NC) and municipal and provincial regulations (dBA). The complete measurements are used for calculations and for the design of noise control / reduction means.

Environemental noise surveys

  • Urban environments
  • Routes
  • Railways
  • Industries

Governments and municipalities establish environmental noise requirements to prevent noise pollution from road and rail transport and industries. Sonar acoustical consultants carries out comprehensive on-site studies to assess environmental noise levels, among others for future residential construction and development projects.
