Beskrivelse

This International Standard specifies four methods for the determination of the sound power levels
of high-frequency noise emitted by machinery and equipment in the frequency range covered by the
octave band centred at 16 kHz, which includes frequencies between 11,2 kHz and 22,4 kHz. They are
complementary to the methods described in ISO 3741 and ISO 3744. The first three methods are based
on the reverberation test room technique. The fourth method makes use of a free field over a reflecting
plane.
The test conditions which prescribe the installation and operation of the equipment are those specified
in ISO 3741 or ISO 3744 as applicable.
