High Amplitude and High Frequency ½

High Amplitude and High Frequency ½" Measurement Microphone

14 September 2015
Free-field, ½" microphone minimizes overloading

PCB Piezotronics, Inc.: A new free-field microphone, model 377A06 from PCB Piezotronics, Inc. provides an accurate (flat) response in applications where high frequencies (up to 40 kHz) need to be measured very accurately. The 377A06 avoids an overload that can be experienced when a standard high sensitivity (50 mV/Pa) microphone measures over 136 dB or above 20 kHz. This microphone is a cost effective alternative to a ¼" microphone and preamplifier combination and has a much lower inherent noise.

Common applications for this high amplitude, high frequency microphone include environmental monitoring, railway testing for horns above 140dB and sonic boom measurements.

Key benefits of the 377A06 include the ability to measure to 40 kHz (+/- 3 dB), a 3% distortion rating to 160 dB, and a cost effective ½" package that maintains a 21 dBA noise floor.

PCB® carries a full complement of prepolarized and externally polarized condenser microphones and preamplifiers. Prepolarized microphones use standard coaxial cables and are ICP® compliant, allowing power supplies to be shared with other ICP® compliant products such as accelerometers, pressure and force sensors. This interchangeability can result in a significant per-channel cost savings as well as reduce test set-up time. PCB products are backed by our best in class warranty and Total Customer Satisfaction policy.

Model 377A06 is a stock item and available for immediate shipment. For additional information please visit or contact Mark Valentino, Product Manager, at (866) 816-8892 or email at .
