calibration records, contractual regulations, and risk associated with incorrect readings. PCB
recommends 12 to 24 month intervals, depending upon the above factors. Contact your PCB
representative to schedule factory recalibration of your microphone, or you can also calibrate the
microphone on site using PCB’s handheld CAL250 Acoustic Calibrator.
In addition, environmental factors will impact the microphone’s sensitivity. Changes in
temperature, humidity and atmospheric pressure can cause a microphone’s sensitivity to change.
To account for this, many end users perform a single-point sensitivity, in-the-field calibration. To
perform this calibration for the 130B40 Microphone we recommend using a handheld CAL250
Acoustic Calibrator.
If you have a handheld calibrator, before performing a calibration, ensure the microphone has
stabilized in the environment in which it will be used. This can take a few seconds to a few
minutes, depending upon the extent of the environmental change. To perform the calibration,
install the fairing pad onto the 130B40 Surface Microphone to help ensure a proper seal. Place
the microphone and fairing pad on a flat, level surface. Turn the handheld calibrator upside down,
and place the 1” (25mm without the adapters) opening onto the fairing, centered around the
microphone sensing element. Press down slightly to ensure a seal and to minimize outside noise,
then perform the calibration using the instructions provided in the calibrator’s manual.
