Performing a quick field check
Click on the “Compass” button from the “Tools” tab:
Locate the sound intensity towards the sound source and check the compass indicator:
The compass indicator should be in the red region indicating a PI index inferior to 3 dB and positive
intensity.
Locate the sound intensity away from the sound source and check the compass indicator. Be sure
to locate the sound probe at the same point. You can use a tripod or a similar object as a reference
point.
The compass indicator should be in the blue region indicating a PI index inferior to 3 dB and
negative intensity.
Note that pressure and intensity levels should be very close when pointing towards and away from
the source.
