Acoustics. Field measurements of airborne and impact sound insulation and of service equipment sound. Survey method Ingestion-build-183511 11 and BS 4903 which1 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 faades; 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
