This document specifies field survey methods for measuring:
a) airborne sound insulation between rooms;
b) impact sound insulation of floors;
c) airborne sound insulation of façades; and
d) sound pressure levels in rooms caused by service equipment.
The methods described in this document are applicable for measurements in rooms of dwellings or in rooms of comparable size with a maximum of 150 m3.
For airborne sound insulation, impact sound insulation and façade sound insulation the method gives values which are (octave band) frequency dependent. They can be converted into a single number characterising the acoustical performances by application of EN ISO 717-1 and EN ISO 717-2. For service equipment sound the results are given directly in A - or C -weighted sound pressure levels.
