Annex A Coaxial circular paths in parallel planes for microphone
traverses in a free field over a reflecting plane
Annex B Calculation of air absorption coefficient
Specifies four methods for the determination of sound power levels in the frequency range between 11,2 kHz and 22,4 kHz with the centre frequency of 16 kHz. The first three methods are based on the reverberation room technique, the fourth on a free field over a reflecting plane.
