based PC, the MEZZO Intensity Probe benefits from the
versatility and flexibility provided by computers. This approach
allows the MEZZO Intensity Probe along with the MEZZO
Intensity Analyzer Module to be offered at a very competitive
price.
• Intensity Analyzer (included)
• I-Track for Mezzo (optional)
Used along with the MEZZO Intensity Analyzer Module, the
MEZZO Intensity Probe complies with IEC 61043 (1993) standard.

Mezzo I-Track System (Optional)
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 MEZZO 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
the 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 MEZZO 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 MEZZO I-Track System provides invaluable
information in many fields of acoustics such as
product manufacturing, consulting, and laboratory
experiments.

Mezzo I-Track System (Optional)
The MEZZO I-Track System uses a digital camera and a
tracking device 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 precise. Sound intensity, pressure and PI index levels
can be plotted for every frequency band as well as the 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 MEZZO I-Track Software Module offers the same sound
intensity processing features as the MEZZO Intensity Analyzer
Module such as the phase mismatch compensation filters,
class 0 digital filters and 64-bit computing offering the
highest level of precision.
The MEZZO I-Track system along with the MEZZO Sound
Intensity Probe offers a high-quality, unrivaled, real-time
sound imagery system at an unbeatable price.
