This document specifies procedures to determine the impact sound insulation using sound pressure measurements with an impact source operating on a floor or stairs in a building. These procedures are intended for room volumes in the range from 10 m³ to 250 m³ in the frequency range from 50 Hz to 5 000 Hz. The test results can be used to quantify, assess and compare the impact sound insulation in unfurnished or furnished rooms where the sound field may or may not approximate to a diffuse field.rd edition 2020-07 Acoustics — Field measurement of sound insulation in buildings and of building elements — Part 2: Impact sound insulation Acoustique — Mesurage in situ de l'isolation acoustique des batiments et des éléments de construction — Partie 2: Isolation des bruits d'impacts Reference number ISO 16283-2:2020(E) ？ ISO 2020 ISO 16283-2:2020(E) COPYRIGHT PROTECTED DOCUMENT ？ IS
