What is
Sound Insulation Testing?

A sound insulation test or airborne sound insulation test is a method of detecting whether houses and flats are retaining noise within the confinements of the dwelling. The test calculates how much noise is escaping through the walls, floor and ceiling of the building. 

Different sound insulation tests are conducted dependant on the type of house or flat being tested. An airborne sound insulation test occurs on the dividing walls between two flats or houses, whereas the airborne and impact sound insulation test is conducted on the floor of the flat or house. 

Sound Insulation Testing must be completed in order to pass document E of building regulations. Without this approved document it is illegal to rent or sell your property.

for Testing

Sound insulation testing needs to be completed when you’re building it at a stage before completion.

The list below indicates what is needed in the building for an accurate test to take place:

  • 110v or 240v power needs to be available in the building

  • All soil pipes should be filled with water

  • Access to all rooms in the building is required
