5.4.2 UNITS CONVERSION
Opening this tab you can define the following:
- Enter the microphone sensitivity and the microphone response correction.
- Enter all other transducers sensitivity and reference levels.
MICROPHONE SENSITIVITY
When taking acoustical measurements, the readings and the scales will be in
Pascals (Pa, dBSPL, dBPa or dBPa/V). In this case, the software will assume that
you are measuring a pressure quantity and it therefore needs to know a conversion
factor that defines the voltage produced by the microphone when it is measuring a
certain pressure. This conversion factor is usually the sensitivity of the microphone
(as found in the microphone’s calibration chart) or the sensitivity of the microphone
+ preamplifier chain of equipment.
If you are working with the CLIO system standard accessories there are two
possible cases:
a) you may use a microphone MIC-01, MIC-02 or MIC-03 directly connected to FW-
01; it is necessary to input the sensitivity of the microphone (in mV/Pa)
increased of 3.3dB i.e. multiplited by 1.465.
b) you are using the PRE-01 preamplifier, it is necessary to know its internal gain;
if it is 0dB then input the microphone sensitivity, if it is +20dB then input the
microphone sensitivity multiplied by 10.
NOTE: It is necessary to input two separate sensitivities, one for channel A and one
for channel B.
Please also refer to 8.4.1 for a description of the procedure for assessing
the sensitivity of the microphonic chain using an acoustic calibrator
capable of producing 94dBSPL.
