Sound Tests may take the form of an Airborne test, an Impact test or both depending on whether the acoustic properties of Walls, Floors or Ceilings are required to be proven. Airbourne Sound Testing is the measurement of how much sound is stopped by separating walls or floors between dwellings and rooms such as bedrooms, classrooms, hotel rooms, offices etc. This is carried out by making a controlled noise on one side of the separating wall or floor and measuring how much sound is being received on the other side. This allows us to calculate how much sound is stopped by the structure under test. Normally the larger room will house the Sound Source and the smaller room, the Receiver.
Technical Guidance Document E, (TGD E Ireland) of the Building Regulations requires new buildings and conversions to demonstrate reasonable levels of airborne and impact sound insulation performance between separating walls and floors.
