General
The measurements have to be carried out in compliance with the
respectively applicable standards.
For all tests (measurements) follow the safety references as des-
cribed
Direct the measurement microphone towards the sound emitting
source.
To minimise operator influence on the measurements make sure
that the sound level meter is placed at a distance of approx. 50
cm away from the body or mounted onto a tripod. The operator
body acts as a sound reflector and can lead to an error of mea-
surement of up to ± 6dB.
During the measurement process, ensure that any persons pre-
sent do not influence the sound field, i.e. under no circumstance
should the persons be present within the sound field.
