Sound Intensity Probes, Software, etc.

Couplers for calibrating the phase response of microphone pairs used for measuring sound intensity.

Phase-matched microphones for sound intensity measurements.

A sound Intensity probe holds two closely-spaced phase-matched microphones. The method is based on the simultaneous determination of sound pressure and particle velocity. The sound intensity probe must ensure a well-defined acoustic spacing between the microphones as well as minimise disturbances to the sound field.

A probe power supply provides the special voltages for supply and polarization required by measurement microphones and preamplifiers. Probe power supply can also accommodate remote control capabilities of some sound intensity probes.

Software for the post-process and display of Acoustic Intensity, Sound Pressure Level, and Sound Power.
