Acoustics - Field measurement of sound insulation in buildings and of building elements - Part 2: Impact sound insulation (ISO 16283-2:2020)

EN-ISO 16283-2 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.

Akustik - Messung der Schalldämmung in Gebäuden und von Bauteilen am Bau - Teil 2: Trittschalldämmung (ISO 16283-2:2020)

Dieses Dokument legt Verfahren zur Bestimmung der Trittschalldämmung durch Schalldruckmessungen mit einer auf einer Decke oder auf Treppen in einem Gebäude wirkenden Trittschallquelle fest. Diese Verfahren sind für Raumvolumen im Bereich von 10 m3 bis 250 m3 und den Frequenzbereich von 50 Hz bis 5 000 Hz vorgesehen. Die Prüfergebnisse können genutzt werden, um die Trittschalldämmung in unmöblierten oder möblierten Räumen quantitativ zu bestimmen, zu beurteilen und miteinander zu vergleichen, wobei das Schallfeld etwa einem diffusen Schallfeld entsprechen oder nicht entsprechen kann.

Acoustique - Mesurage in situ de l'isolation acoustique des bâtiments et des éléments de construction - Partie 2: Isolation des bruits d'impacts (ISO 16283-2:2020)

Le présent document spécifie les modes opératoires permettant de déterminer l'isolation des bruits d'impacts à l'aide de mesurages de la pression acoustique avec une source d'impacts agissant sur un sol ou sur un escalier à l'intérieur d'un bâtiment. Ces modes opératoires s'appliquent aux pièces dont le volume est compris entre 10 m3 et 250 m3 et dont la fréquence est comprise entre 50 Hz et 5 000 Hz. Les résultats des essais peuvent être utilisés pour quantifier, évaluer et comparer l'isolation des bruits d'impacts dans des pièces non meublées ou meublées où le champ acoustique peut, ou ne peut pas, être assimilé à un champ diffus.

Introduction

ISO 16283 (all parts) describes procedures for field measurements of sound insulation in buildings.

Airborne, impact and façade sound insulation are described in ISO 16283-1, this document (ISO 16283-2)

and ISO 16283-3, respectively.
1) 2)

Field sound insulation measurements that were described previously in ISO 140-4 , ISO 140-5 , and

ISO 140-7 were a) primarily intended for measurements where the sound field could be considered

to be diffuse, and b) not explicit as to whether operators could be present in the rooms during the

measurement. ISO 16283 (all parts) differs from ISO 140-4, ISO 140-5, and ISO 140-7 in that:

a) it applies to rooms in which the sound field may or may not approximate to a diffuse field;

b) it clarifies how operators can measure the sound field using a hand-held microphone or sound

level meter;
c) it includes additional guidance that was previously contained in ISO 140-14 .

NOTE Survey test methods for field measurements of airborne and impact sound insulation are dealt with in

ISO 10052.

Two impact sources are described: the tapping machine and the rubber ball. These impact sources do

not exactly replicate all possible types of real impacts on floors or stairs in buildings.

The tapping machine can be used to assess a variety of light, hard impacts such as footsteps from

walkers wearing hard-heeled footwear or dropped objects. A single number quantity can be calculated

using the rating procedures in ISO 717-2. This single number quantity links the measured impact

sound insulation using the tapping machine to subjective assessment of general impacts in dwellings

that occur on floors or stairs in a building. The tapping machine is also well-suited to the prediction

of impact sound insulation using ISO 12354-2. These two aspects facilitate the specification of impact

sound insulation in national building requirements using only measurements with the tapping machine

as an impact source.

The rubber ball can be used to assess heavy, soft impacts such as from walkers in bare feet or children

jumping, as well as quantifying absolute values that can be related to human disturbance in terms of a

Fast time-weighted maximum sound pressure level.

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

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.
