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 ISO 717-1 and ISO 717-2. For heavy/soft
impact sound insulation, the results also are given as A-weighted maximum impact sound pressure
level. For service equipment sound the results are given directly in A - or C -weighted sound pressure
