Industry’s First 1/2” Prepolarized Low Noise Microphone System

PCB Piezotronics introduced a new 1/2” low noise microphone and preamplifier system, model 378A04, which enables test engineers to measure extremely low sound pressure levels in a cost effective, prepolarized (0V) package. Applications include measurements for fan tests, appliance noise, electric car sound quality, environmental noise, cabin noise & anechoic chamber qualification.
