Measurement of sound insulation in buildings and of building elements -- Field measurements of impact sound insulation of floors
FIELD MEASUREMENTS OF IMPACTS
Measures the impact sound insulation between a pair of rooms.
The steady state 1/3 octave band filtered receiving room sound pressure level is measured while a standardized tapping machine is hammering on the test floor.
Determines the receiving room equivalent absorption area and derives the normalized/standardized impact sound pressure level.
The results can be used to determine whether floors have met acoustic specifications, e.g. Building Regulations.
