Insertion attenuation with ogive
The insertion attenuation is the ability of the silencer to reduce the internal noise of the ventilation duct, usually caused by the fan. It is measured as the difference between the upstream sound power level and the downstream sound power level of the silencer, both expressed in thirds of an octave and without air passage.
