When acoustic measurements need to be made in demanding environments and applications, a variety of PCB® specialty microphones are available.

Low Noise Prepolarized Microphone

Low Frequency Microphone System

This 1/2" microphone and preamplifier system, model 378A07 aids in low frequency testing, ideal for infrasound measurements and studies ranging from wind turbines to natural events like tornadoes. Model 378A07 is comprised of a 1/2” (12mm) 377A07 prepolarized microphone, a 426E01 preamplifier, and a low frequency filter adapter, Model 079A43. Low frequency measurements are commonly required for wind turbines, sonic booms, diesel engines and specialized loudspeaker systems to name a few.

Surface Microphones

Surface Microphones

These low profile microphones are used for measuring true surface pressure and noise. Its footprint allows noise measurements to be taken where traditional microphones will not fit. A water and dust resistant grid cap is ideal for dirty and rough environments. Typical applications include wind tunnel noise measurements, brake noise, acoustic fatigue analysis, and clear air turbulence (CAT) testing.

Prepolarized Probe Microphone

Prepolarized Probe Microphone

The small profile Probe Microphone is used for acoustic measurements in small, hard-to-reach places and where precise placement is required in near-field testing within confined areas. This probe microphone is used in extremely high temperatures environments (800◦C).

Side Vented Pressure Field Microphones

Side Vented Pressure Field Microphones

These microphones can be flush mounted in a cavity, tube, wall or panel. This design allows for equalization of atmospheric pressure between the inside of the microphone and the outside of the structure. They are recommended for applications such as impedance tube testing, HVAC testing, and where high sound pressure levels or high frequency measurements are required.
