I-Track
Sound Intensity Imaging System
The adage “A picture is worth a thousand words” has
never been truer in the field of acoustics. The translation
of complex acoustical phenomena can be a hard task
especially when it comes to informing non-technical
clients. Wouldn’t it be easier just to take a picture? The
answer is YES!
The I-Track System is a powerful tool for easy, fast and
accurate sound imagery. The images are created by
combining the acoustic data provided by a MEZZO Sound
Intensity Probe with its position provided by a camera-
based tracking device in real-time. The result is a high-
definition sound image performed in a few minutes.
The I-Track System offers a complete solution to create
sound imagery both in the field and in laboratory. Its
compact system makes it easy to carry and fast to setup a
measurement.
The I-Track System provides invaluable information in
many fields of acoustics such as product manufacturing,
consulting, and laboratory experiments.

Quick and Easy: YES! Compromise on Accuracy: NO!
The I-Track System uses an optical tracking system to
precisely locate the sound intensity probe in space.
While you scan the measurement surface, the probe position
is tracked for each acoustic measurement interval (typically
10 times a second).
Every measurement point is drawn on the picture in real-
time creating the sound map on the screen as you scan the
measurement surface.
The resulting pictures are not only great looking, but are also
highly accurate. Sound intensity, pressure and PI index levels
can be plotted for every frequency band as well as for global
level. Correspondingly, the associated spectrum shows the
spatial average of pressure, intensity, PI index (F3), P|I| index
(F2), Extraneous sources index (F3-F2) and sound power.
The I-Track system offers proprietary phase mismatch
compensation filters, class 0 digital filters and 64-bit
computing offering the highest level of precision.
The I-Track system offers a high-quality, unrivaled, real-time
sound imagery system at an unbeatable price.
