There are two types of sound testing: airborne and impact tests.
Airborne sound testing involves placing a loudspeaker on one side of a partition wall while measuring noise levels on the other side to assess sound insulation.
Impact testing is carried out using a tapping machine on the floor, with noise levels recorded in the room below to evaluate sound transmission.
Under the Building Regulations, walls and floors between adjoining dwellings must undergo sound testing to ensure noise transfer remains within acceptable limits. The number of tests required for Part E compliance depends on the size of the development. However, for a typical small to medium-sized project (fewer than 10 dwellings with similar construction), the standard sound testing requirements generally include:
2 airborne wall tests
2 airborne floor tests
2 impact floor tests
