1" Pressure Response Prepolarized Microphone

For low frequency and low noise measurements

Applications:

  • Precise sound level meter measurements
  • For use with IEC 60318-3 couplers
  • Audiometer calibration
  • Testing sound booths
  • Calibration transfer standards

Highlights:

  • Prepolarized (0V) design
  • Low noise floor 10 dBA typical
  • IEC 61094-4 WS1P compliant
  • For use with Class 1 sound level meter for low noise measurements

A pressure microphone is designed to measure the pressure response. A pressure response occurs when the microphone is flush mounted at the boundary of a sound field. Pressure microphones accurately measure the sound pressure in ducts, cavities, impedance tubes, wind tunnels, and couplers. They are ideal for audiometer calibration, sound level meter measurements, ear simulators, calibration transfer standards, and testing of sound booth noise levels.

The 377A15 is a prepolarized (0V) microphone. Prepolarized microphones, when combined with ICP® preamplifiers, are interchangeable with many other styles of ICP® sensors (accelerometers, strain gages, force sensors, piezoelectric pressure sensors). ICP® sensors work with a wide variety of data acquisition systems which utilize 2-20mA constant current, low cost cabling, and cost effective signal conditioning/power supplies.
