Microphones

Piezoelectric Microphones are transducers used to convert acoustic sound into an electric signal. Piezoelectric microphones are designed based on the piezoelectric effect resulting from properties of the piezoelectric materials that audio waves bend the piezoelectric material generating a changing voltage as the analog output. Piezoelectric microphones are used with high frequency sound finding applications in NVH (Noise, Vibration, and Harshness) testing, cabin noise analysis, pass-by noise testing, environmental noise analysis, building noise studies, acoustic chamber testing, appliance noise evaluation, wind tunnel and aerodynamics testing, as well as medical imaging and industrial Non-Destructive Testing.
