Acoustics. Measurement of airborne noise emitted by information technology and telecommunications equipment Ingestion-build-86103 ultraviolet degradation or other methodsWhat is ISO 7779 Measurement of airborne noise about? ISO 7779 is an international standard that discusses acoustics. ISO 7779 specifies procedures for measuring and reporting the noise emission of information technology and telecommunications (ITT) equipment. The basic emission quantity is the A weighted sound power level, which can be used for comparing equipment of the same type but from different manufacturers, or for comparing different
