Electroacoustics. Sound level meters - Pattern evaluation tests Ingestion-build-63436 and software that controls machinery1 Scope This part of IEC 61672 provides details of the tests necessary to verify conformance to all mandatory specifications given in IEC 616721 for time weighting sound level meters, integrating averaging sound level meters, and integrating sound level meters. Pattern evaluation tests apply for each channel of a multi channel sound level meter, as necessary. Tests and test methods are applicable to class 1 and class 2 sound level meters. The aim is
