A Particle velocity probe is a probe capable of measuring the acoustic particle velocity.
The only particle velocity probe to date has been produced by Microflown Technologies and is called the Microflown.
To model a tri-axial particle velocity probe's measurement of a source incident from the near field, see:
The tri-axial particle velocity probe's azimuth-elevation beam pattern:
A tri-axial particle velocity probe may be used to enhance speech reception in a video conferencing scenario:
