level based on free-field measurements
A.1 A sound level meter located with its microphone at
the centre of a sphere and a reference direction for
sound incidence aligned with the X-axis
A.2 A sound level meter under test mounted on a turntable
to obtain incidence of sound from different directions
in the X-y plane
A.3 Method of simulating rotation in the X-Z plane by 90
degrees rotation of the sound level meter under test
around an axis coincident with the reference
direction, and then rotation around a circle in the
X-Y plane as in figure A.2
Describes a free-field calibration method for determining random-incidence sensitivity levels of sound level meters.
