4.1.1
Sound Pressure Calibration and Pressure-Residual Intensity Index Verification
PULSE LabShop does not include Type 4297 in its choice of calibrators.
Before you can calibrate a sound intensity probe, a number of conditions must be met:
In the Configuration Organiser, there must be a signal for each of the two channels you are
using for the sound intensity probe. These signals must be members of the same signal
group.
A transducer must be added to or selected from the Transducer Database for both channels
for the probe. Remember that the microphone transducers must be of the same type and
should be a paired set.
In the Measurement Organiser, there must be a CPB analyzer inserted in the measurement
template that you are going to calibrate from, and the signal group containing the two signals
from the probe must be connected to it.
In the Calculation tab page for the CPB analyzer, measurement of mean pressure and
intensity (or measurement and storage to the multi-buffers) for the signal group containing
the signals from the probe microphone channels must be selected.
For sound pressure calibration you can then use a generic acoustical calibrator.
For pressure-residual intensity index, you need to add a function in the Function Organiser
and in the Function properties select Calculation of the
to create a display.
