Microphones for Aerospace/Acoustic Applications

The identification of noise sources is necessary to evaluate and reduce noise levels. Vibration at frequencies undetectable by the human ear may cause noise that can only be measured by microphones. Measuring the frequency of the noise is important because it helps engineers determine the method of acoustic treatment to help reduce the noise. Noise sources are measured with a large variety of prepolarized, externally polarized, array and specialty microphones, and are complemented by an assortment of preamplifiers, signal conditioners, calibrators, and accessories like mounting stands a nose cones.

PCB® offers a variety of acoustic measurement products, including condenser, prepolarized, externally polarized, array, probe, low-profile surface, and special purpose microphones. PCB® Microphone products are complemented by an assortment of preamplifiers, signal conditioners, A-weighting filters, handheld calibrators, and accessories.
