The Microflown PU probe is able to simultaneously measure multiple acoustic properties such as sound pressure and particle velocity at any point of a sound field. As the only probe that can directly capture the complex acoustic behaviour present in the near field, detailed acoustic information becomes easily available to accurately find and quantify the acoustic output of multiple sound sources. The broadband response of the probe covers the complete frequency range from 20 Hz to 10000 Hz, without the need of introducing any assumptions or computational errors.

Features include:

  • Broad Band | 20Hz -10kHz
  • Compact design
  • High spatial resolution
  • Low susceptibility to P/I
  • Less dependent on environment conditions

Applications:

  • Sensor array applications
  • Noise Source Identification
  • Configurable grids for Near Field Acoustic Camera
  • Range of Acoustic quantities: Sound Intensity, Sound Power, PVL measurements
