PCB Piezotronics’s New Model 130A23 Measurement Microphone

PCB Piezotronics’s new Model 130A23 high-amplitude array microphone is designed to enable research engineers to locate noise sources in appliances, machinery, aircraft, and automotive interiors. This all-in-one prepolarized microphone and preamplifier measures acoustic signals in the audible range of the human ear with the extended dynamic and frequency range often found on more expensive condenser microphones.
