PCB Piezotronics Announces New Side Vented Condenser Microphone Model

Designed for High Frequency and High Amplitude Applications

March 28, 2013, Depew, NY - PCB Piezotronics, Inc., a global leader in acoustic, vibration, pressure, force, and torque sensors with over 30 years of microphone manufacturing experience is pleased to announce the release of new Model 377A14 Side Vented 1/4" Condenser Microphone. The 377A14 microphone is designed for use in very high frequency (100 kHz) and high amplitude (174 decibels) applications.

The Model 377A14 features a side vented design providing a greater degree of accuracy when the microphone is flush mounted in a wall or tube where there are significant pressure differentials between the inside and outside of the tube or wall. Typical applications include testing of panels, airplane wing testing, HVAC, sound absorption in impedance tube tests, or general high amplitude or high frequency sound or noise measurements in cavities or small enclosures.

Model 378A14 is a Pressure Field microphone and preamplifier combination which combines the 377A14 microphone with a matching 426A05 preamplifier to help minimize leakage of external atmospheric pressure. This is available with TEDS (Transducer Electronic Data Sheets) programming for traceability of model, serial number, sensor location, sensitivity, and additional calibration information. These models are IEC 61094 compliant and are based on ICP® sensor technology.
