ISO 7779:2018 is an international standard that specifies a method for measuring and reporting the airborne noise emitted by information technology and telecommunications equipment. It's a standard within the broader field of acoustics, aiming for reliable and reproducible noise emission measurements. The standard is used to determine the sound power levels and emission sound pressure levels of such equipment, which can then be used for noise emission declaration, comparison, and installation planning.
