Sets of tests in flats and maisonettes with separating floors but without separating walls
For flats and maisonettes with only separating floors, one set of tests normally comprises four individual sound insulation tests: two airborne tests and two impact tests, measured between pairs of living rooms and pairs of bedrooms on opposite sides of the separating floor.
Normally, one set of tests should comprise four individual sound insulation tests (two airborne tests, two impact tests) – (a) tests of insulation against both airborne and impact sound between one pair of rooms (where possible suitable for use as living rooms) on opposite sides of the separating floor; and (b) tests of insulation against both airborne and impact sound between another pair of rooms (where possible suitable for use as bedrooms) on opposite sides of the separating floor.
