Electroacoustics - Sound level meters - Part 1: Specifications
Gives electroacoustical performance specifications for three kinds of sound measuring instruments: - a conventional sound level meter that measures exponential time-weighted sound level; - an integrating-averaging sound level meter that measures time-average sound level; and - an integrating sound level meter that measures sound exposure level. A single instrument may make any, or all, of the three kinds of measurements. Two performance categories, class 1 and class 2, are specified in this standard. In general, specifications for class 1 and class 2 sound level meters have the same design goals and differ mainly in the tolerance limits and the range of operational temperatures. Tolerance limits for class 2 specifications are greater than, or equal to, those for class 1 specifications. Sound level meters conforming to the requirements of this standard have a specified frequency response for sound incident on the microphone from one principal direction in an acoustic free field or from random directions.
Elektroakustik - Schallpegelmesser - Teil 1: Anforderungen
Electroacoustique - Sonomètres - Partie 1: Spécifications
Donne des spécifications pour les caractéristiques électroacoustiques de trois types d'instruments de mesure acoustique: - le sonomètre conventionnel, qui mesure le niveau de pression acoustique avec une pondération temporelle exponentielle; - le sonomètre intégrateur-moyenneur, qui mesure le niveau continu équivalent de pression acoustique; - le sonomètre intégrateur, qui mesure le niveau d'exposition au bruit. Le même instrument peut effectuer un des types de mesure ou les trois. Deux catégories de caractéristiques correspondant à deux classes de sonomètres, la classe 1 et la classe 2, sont spécifiées dans la présente norme. Généralement, les spécifications concernant les sonomètres de classe 1 et de classe 2 correspondent aux mêmes caractéristiques nominales et ne diffèrent principalement que par les limites de tolérances et le domaine des températures de fonctionnement. Les limites de tolérance concernant les spécifications de la classe 2 sont supérieures ou égales à celles des spécifications de la classe 1. Les sonomètres conformes aux prescriptions de la présente norme présentent une réponse en fréquence spécifiée pour des ondes acoustiques incidentes sur le microphone suivant une direction principale dans un champ acoustique libre ou suivant des directions aléatoires.

This European Standard was approved by CENELEC on 2003-02-01. CENELEC members are bound to
comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European
Standard the status of a national standard without any alteration.
Up-to-date lists and bibliographical references concerning such national standards may be obtained on
application to the Central Secretariat or to any CENELEC member.
This European Standard exists in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CENELEC member into its own language and
notified to the Central Secretariat has the same status as the official versions.
CENELEC members are the national electrotechnical committees of Austria, Belgium, Czech Republic,
Denmark, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta,
Netherlands, Norway, Portugal, Slovakia, Spain, Sweden, Switzerland and United Kingdom.

Foreword
The text of document 29/507/FDIS, future edition 1 of IEC 61672-1, prepared by IEC TC 29,
Electroacoustics, in cooperation with the International Organization of Legal Metrology (OILM), was
submitted to the IEC-CENELEC parallel vote and was approved by CENELEC as EN 61672-1 on
2003-02-01.
This European Standard, in conjunction with EN 61672-2, supersedes EN 60651:1994 + A1:1994 +
A2:2001 and EN 60804:2000.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2003-11-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2006-02-01
Annexes designated "normative" are part of the body of the standard.
Annexes designated "informative" are given for information only.
In this standard, annexes A and ZA are normative and annexes B and C are informative.
Annex ZA has been added by CENELEC.
