1.0 Introduction
Congratulations on the purchase of a quality ICP

Microphone. In order to ensure the highest
level of performance of the Microphone, we recommend that you follow the product’s basic
installation and operation procedures. By following these procedures and using this Microphone
in conjunction with other PCB equipment (Signal Controllers, Power Supplies, Cables,
Calibrators, etc.), you will ensure years of trouble free usage. If after reading this manual, you
have additional questions concerning the Microphone or its application, feel free to call a factory
Application Engineer at 716-684-0001, or your local dedicated PCB Sales Engineer.
2.0 Product Description
The PCB 130B series of Surface Microphones are prepolarized, condenser microphones coupled
with ICP

sensor powered preamps and are thus referred to as ICP

microphones. This eliminates
the need to purchase a separate preamplifier. The 130B40 Surface Microphone provides an
extremely cost effective method for making general purpose measurements on flat and curved
surfaces subjected to air movement. Typical applications include measuring wind-induced noise
on ground and airborne vehicles, acoustic radiation from surfaces, and noise tests in wind
tunnels, as well as comparing the external noise on a moving vehicle with its internal noise,
along with other applications. The low profile of the 130B40 Microphones (0.126”/3.2 mm)
allows their use in tight-fitting places where other microphones would not fit.
