Introduction

Methods of measurement of impact sound insulation in buildings and of building elements haves e r s a s s o e oo o u as insulation which are frequency dependent. The purpose of this document is to standardize a method whereby the frequency-dependent values of impact sound insulation can be converted into a singlenumber characterizing the acoustical performance.
