NF EN ISO 10052/A1

<p>This document specifies field survey methods for measuring</p> <p>a) airborne sound insulation between rooms,</p> <p>b) impact sound insulation of floors,</p> <p>c) airborne sound insulation of façades, and</p> <p>d) sound pressure levels in rooms caused by service equipment.</p> <p>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.</p> <p>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 <em>A</em> - or <em>C</em> -weighted sound pressure levels.</p>
