Floors and walls - noise

Our assessments of acoustical performance (airborne sound insulation and impact sound insulation) of floors and walls include:

 

  1. verification of compliance with requirements of Building Code of Australia (BCA) - assessment of transmission of sound (noise) between adjacent dwellings (impact noise, e.g. footfall noise, i.e. noise caused by people walking over a timber floor, and airborne noise, e.g. noise from TVs, amplified music systems, noise from conversations);

  2. determination of building facade insulation using traffic noise, by two-channel measurements with world-renowned
    Brüel and Kjær (B&K) Modular Precision Real-Time Sound Analyzers type 2270;
     
  3. in situ determination of impact sound insulation of floors according to Australian/New Zealand Standard: Acoustics - Measurements of sound insulation in buildings and of building elements - Part 7: Field measurements of impact sound insulation of floors (AS/NZS ISO 140.7:2006), using the tapping machine;
     
  4. in situ determination of airborne sound insulation between rooms according to Australian Standard/ISO 140.4-2006: Acoustics - Measurements of sound insulation in buildings and of building elements - Part 4: Field measurements of airborne sound insulation between rooms (ISO 140-4: 1998), using loudspeakers with synthetic, "pink" or "white" noise;

  5. in situ determination of airborne sound insulation between rooms and of building elements: measurements according to ISO 15186-1:2000 - Acoustics: Measurements of sound insulation in buildings and of building elements using sound intensity; and based on these measurements, calculations of the Weighted Sound Reduction Index (Rw) (replacement of Sound Transmission Class - STC) according to Australian/New Zealand Standard: Acoustics - Rating of sound insulation in buildings and of building elements - Part 1: Airborne sound insulation (AS/NZS 1276.1:1999 and ISO717-1:1996);

  6. scanning of walls, windows, doors, ceilings and floors to discover areas of noise penetration - control of noise transmitted between adjacent rooms, control of intrusion of external noise and control of noise escaping from clubs, discotheques, hotels, restaurants and pubs;
     
  7. evaluation of apartments and townhouses (evaluation of sound insulation properties of floors and walls) according to Acoustical Star Ratings for Apartments and Townhouses of Association of Australian Acoustical Consultants (AAAC).
