GSO IEC 61043:2015 Scope

The primary purpose of this Standard is to ensure the accuracy of measurements of sound intensity applied to the determination of sound power in accordance with ISO 9614-1. To meet the requirements of that standard, instruments are required to analyse the sound intensity in one-third octave or octave bands, and optionally to provide A-weighted band levels. They are also required to measure sound pressure level in addition to sound intensity level to facilitate the use of the field indicators described in ISO 9614-1. This International Standard only applies to instruments which detect sound intensity by pairs of spatially separated pressure sensing microphones. This International Standard specifies performance requirements for instruments used for the measurement of sound intensity, and their associated calibrators. The requirements are intended to reduce to a practical minimum any differences in equivalent measurements made using different instruments, including instruments comprising probes and processors from different manufacturers.
