Calibration
Acoustical
-
with
the SV 36 sound calibrator
(or equivalent):
•
Calibration level for the pressure field
114.0 dB (equal to the calibrator pressure level - see calibration
chart of the used calibrator)
•
Calibration level for the free field and
0 deg incidence angle
113.87 dB (equal to the calibration level for the pressure field
minus free field correction of G.R.A.S. 40AE at 1000 Hz
– see
Table C.1.6)
Note:
The above levels correspond to 114 dB of calibrator’s sound pressure. If the calibrator has
a different sound pressure than 114 dB, the calibration levels must be accordingly adjusted.
Microphone
G.R.A.S. 40AE
prepolarized free-
field ½” condenser microphone
Nominal sensitivity
50 mV/Pa (corresponding to -26 dBV/Pa re 1 V/Pa)
Capacitance
17 pF.
Note: Maximum level of sound pressure level, which can be affect the microphone without destruction
the microphone: 148 dB.
