Electroacoustics. Random-incidence and diffuse-field calibration of sound level meters Ingestion-build-156411 NOTE Some measurement methods defined1 Scope 1. 1 This International Standard describes a free field calibration method for determining random incidence sensitivity levels of sound level meters. Additionally, the standard describes a diffuse field calibration method for determining diffuse field sensitivity levels. 1. 2 For the purpose of this International Standard, diffuse field sensitivity level may be used interchangeably with random incidence sensitivity level.
