Acoustics - Field measurement of sound insulation in buildings and of building elements - Part 1: Airborne sound insulation (ISO 16283-1:2014)

ISO 16283-1:2014 specifies procedures to determine the airborne sound insulation between two rooms in a building using sound pressure measurements. 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 airborne sound insulation in unfurnished or furnished rooms where the sound field may or may not approximate to a diffuse field. The measured airborne sound insulation is frequency-dependent and can be converted into a single number quantity to characterize the acoustic performance using the rating procedures in ISO 717‑1.

Akustik - Messung der Schalldämmung in Gebäuden und von Bauteilen am Bau - Teil 1: Luftschalldämmung (ISO 16283-1:2014)

Dieser Teil der ISO 16283 legt Verfahren zur Bestimmung der Luftschalldämmung zwischen zwei Räumen in einem Gebäude durch Schalldruckmessungen 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 Luftschalldämmung in unmöblierten und möblierten Räumen quantitativ zu bestimmen, zu beurteilen und miteinander zu vergleichen, wobei das Schallfeld etwa einem diffusen Schallfeld entsprechen darf, dies jedoch nicht muss. Die gemessene Luftschalldämmung ist von der Frequenz abhängig und kann in eine Einzahlangabe umgewandelt werden, um unter Anwendung der Bewertungsverfahren nach ISO 717-1 die akustische Leistung zu charakterisieren.

Acoustique - Mesurage in situ de l'isolation acoustique des bâtiments et des éléments de construction - Partie 1: Isolation des bruits aériens (ISO 16283-1:2014)

L'ISO 16283-1:2014 spécifie les modes opératoires permettant de déterminer l'isolation des bruits aériens entre deux salles d'un bâtiment à l'aide de mesurages de la pression acoustique. Ces modes opératoires s'appliquent aux salles dont le volume est compris entre 10 m3 et 250 m3 aux fréquences comprises entre 50 Hz et 5 000 Hz. Les résultats des essais peuvent être utilisés pour quantifier, évaluer et comparer l'isolation des bruits aériens dans des salles non meublées ou meublées où le champ acoustique peut ou non être assimilé à un champ diffus. L'isolation mesurée des bruits aériens dépend de la fréquence et peut être convertie en une quantité d'indice unique d'évaluation qui caractérise la performance acoustique à l'aide des méthodes d'évaluation spécifiées dans l'ISO 717‑1.

Akustika - Terenska merjenja zvočne izolirnosti stavbnih elementov in v stavbah - 1. del: Izolirnost pred zvokom v zraku (ISO 16283-1:2014)

Standard 16283-1 določa postopke za ugotavljanje izolirnosti pred zvokom v zraku med dvema prostoroma v stavbi z uporabo meritev zvočnega tlaka. Namenjen je prostorom s prostornino 10–250 m3 v frekvenčnem območju 50–5000 Hz. Rezultate preskusa je mogoče uporabiti za kvantifikacijo, ovrednotenje in primerjavo izolirnosti pred zvokom v zraku v neopremljenih ali opremljenih prostorih, kjer je zvočno polje lahko, ali pa ne, podobno razpršenemu polju. Izmerjena izolirnost pred zvokom v zraku je odvisna od frekvence in jo je mogoče pretvoriti v eno številko za opredelitev akustičnih lastnosti z uporabo ocenjevalnih postopkov v standardu ISO 717-1.

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, ISO 16283-2 and

ISO 16283-3 , respectively.

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

differs from ISO 140-4, −5, and −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 and (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.

1 Scope

This part of ISO 16283 specifies procedures to determine the airborne sound insulation between two

rooms in a building using sound pressure measurements. These procedures are intended for room

3 3

volumes in the range from 10 m to 250 m in the frequency range from 50 Hz to 5 000 Hz. The test

results can be used to quantify, assess and compare the airborne sound insulation in unfurnished or

furnished rooms where the sound field may or may not approximate to a diffuse field. The measured

airborne sound insulation is frequency-dependent and can be converted into a single number quantity

to characterize the acoustic performance using the rating procedures in ISO 717-1.

3.3
low-frequency energy-average sound pressure level in a room

ten times the common logarithm of the ratio of the space and time average of the squared sound pressure

to the square of the reference sound pressure in the low-frequency range (50, 63, and 80 Hz one-third

octave bands) where the space average is a weighted average that is calculated using the room corners

where the sound pressure levels are highest and the central zone of the room where the direct radiation

from any loudspeaker or the nearfield radiation from the room boundaries has negligible influence

Note 1 to entry: L is expressed in decibels.

Note 2 to entry: L is an estimate of the energy-average sound pressure level for the entire room volume.

3.4
reverberation time

time required for the sound pressure level in a room to decrease by 60 dB after the sound source has

stopped
Note 1 to entry: T is expressed in seconds.
3.5
background noise level

measured sound pressure level in the receiving room from all sources except the loudspeaker in the

source room
3.6
fixed microphone

microphone that is fixed in space by using a device such as a tripod so that it is stationary

3.7
mechanized continuously-moving microphone

3.9
manually-held microphone

microphone attached to a hand-held sound level meter or a rod that is hand-held at a fixed position by a

human operator at a distance at least an arm’s length from the trunk of the operator’s body

3.10
partition
total surface of the separating partition between the source and receiving rooms

Note 1 to entry: For two rooms which are staggered vertically or horizontally, the total surface of the separating

partition is not visible from both sides of the partition; hence it is necessary to define the partition as the total

surface.
3.11
common partition
part of the partition that is common to both the source and receiving rooms
3.12
level difference

difference in the energy-average sound pressure levels between the source and receiving rooms with

one or more loudspeakers in the source room which is calculated using Formula (1)

DL=−L (1)
where

L is the energy-average sound pressure level in the source room when its volume is larger than

or equal to 25 m or the low-frequency energy-average sound pressure level (50 Hz, 63 Hz and

80 Hz bands only) in the source room when its volume is smaller than 25 m ;

L is the energy-average sound pressure level in the receiving room when its volume is larger

than or equal to 25 m or the low-frequency energy-average sound pressure level (50 Hz,

63 Hz and 80 Hz bands only) in the receiving room when its volume is smaller than 25 m

Note 1 to entry: D is expressed in decibels.
3.13
standardized level difference

level difference that is standardized to a reference value of the reverberation time in the receiving room

and calculated using Formula (2)

---------------------- Page: 15 ----------------------
SIST EN ISO 16283-1:2014
ISO 16283-1:2014(E)

Note 2 to entry: The level difference is referenced to a reverberation time of 0,5 s because in dwellings with

furniture the reverberation time has been found to be reasonably independent of volume and frequency and

to be approximately equal to 0,5 s. With this standardization, D is dependent on the direction of the sound

transmission if the source and receiving rooms have different volumes; D will be higher when the test is carried

out from a smaller source room to a larger receiving room compared to the reverse situation. For this reason,

regulations that require testing to show compliance with a minimum standard of airborne sound insulation

usually require that the smaller room is used as the receiving room so that the lowest D values are measured.

Note 3 to entry: D provides a straightforward link to the subjective impression of airborne sound insulation.

3.14
apparent sound reduction index

ten times the common logarithm of the ratio of the sound power, W , which is incident on a test element

to the total sound power radiated into the receiving room if, in addition to the sound power, W , radiated

by the test element, the sound power, W , radiated by flanking elements or by other components, is

significant
R'l=10 g (3)
WW+
and the apparent sound reduction index is evaluated using Formula (4)
RD'l=+10 g (4)
where
S is the area of the common partition, in square metres;
A is the equivalent absorption area of the receiving room, in square metres.
Note 1 to entry: R’ is expressed in decibels.

Note 2 to entry: In general, the sound power transmitted into the receiving room consists of the sum of several

components from different elements (walls, floor, ceiling etc.).

Note 3 to entry: R’ can be used to compare field measurements with laboratory measurements of the sound

reduction index, R. In comparison to D it has a weaker link to the subjective impression of airborne sound

insulation.

Note 4 to entry: When R’ is determined in the 50 Hz, 63 Hz and 80 Hz bands using the low-frequency procedure

the link to sound power in Formula (3) is not exact.
3.15
equivalent absorption area
sound absorption area which is calculated using Sabine’s formula in Formula (5)
01, 6V
A= (5)
where
V is the receiving room volume, in cubic metres;
T is the reverberation time in the receiving room.
