1 Scope
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.
