Sound Meter Standards

This part of IEC 61672 gives electroacoustical performance specifications for three kinds of sound measuring instruments: • a time-weighting sound level meter that measures exponential-time-weighted, frequencyweighted sound levels; • an integrating-averaging sound...

This part of IEC 61672 provides details of the tests necessary to verify conformance to all mandatory specifications given in IEC 61672-1 for time-weighting sound level meters, integrating-averaging sound level meters, and integrating sound level meters....

Sound exposure is a physical measure that accounts for both the sound pressure and its duration, at a given location, through an integral-over-time of the square of instantaneous frequency-weighted sound pressure. This International Standard is applicable to instruments for...

This second edition of IEC 61672-3 describes procedures for periodic testing of time-weighting, integrating-averaging, and integrating sound level meters that were designed to conform to the class 1 or class 2 specifications of the second edition of IEC 61672-1. The aim of the...

General This standard describes instruments (sound level meters) for the measurement of certain frequency and time weighted sound pressure levels. Types This standard specifies sound level meters of four degrees of precision, designated Types 0, 1, 2 and 3. 1.3...

IEC 61672-2:2013 provides details of the tests necessary to verify conformance to all mandatory specifications given in IEC 61672-1 for time-weighting sound level meters, integrating-averaging sound level meters, and integrating sound level meters....

This standard specifies requirements for integrating-averaging sound level meters including requirements with respect to power- and ratio-frequency fields and to electrostatic discharge, and the permitted radio-frequency emissions, together with test procedures to verify compliance.

La presente Guida specifica le prove necessarie per la verifica periodica degli strumenti per la misura di livelli di pressione sonora ponderati in frequenza e mediati nel tempo. Gli strumenti sono indicati come "misuratore di livello sonoro" o "fonometro" e possono presentarsi in forme differenti...
