When generating a sound eld based on 3D Audio-
Beamforming technology, signal processing coefcients
for each loudspeaker driver are algorithmically optimized
depending on the target audience area, the Audio
Modules’ locations, as well as areas in the respective
architectural surrounding of the array that shall be
actively avoided by the sound eld.
A single HOLOPLOT Matrix Array can simultaneously
create multiple optimized 3D Audio-Beamforming
sound elds, targeting different areas and reproducing
different content for each of these areas. The 3D Audio-
Beamforming capabilities of a HOLOPLOT Matrix Array
are dependent on the size of the array.

OPTIMIZED SOUND FOR
AUDIENCE AREAS
HOLOPLOT 3D Audio-Beamforming enables the control
of sound wave propagation by adjusting the vertical and
horizontal steering angle and the vertical and horizontal
opening angles. The sound eld of a HOLOPLOT Matrix
Array can be congured individually to adapt to an
installation’s requirements, even when facing complex-
shaped environments or challenging room acoustics.
A sound eld based on HOLOPLOT 3D Audio-Beamforming
technology is usually deployed to provide the following:
• uniformity of coverage (spectral consistency over a
predened audience area)
• improved speech intelligibility
• reduced unwanted sound spill onto stages and into
neighboring residential areas
• eliminated sound from reective surfaces, reducing
the creation of acoustic echo and minimizing room
reverberation artifacts
A HOLOPLOT Audio System can be deployed as single, or multiple arrays of HOLOPLOT
Audio Modules. Each array of Audio Modules can simultaneously generate multiple
sound elds based on two HOLOPLOT core technologies: 3D Audio-Beamforming and
Wave Field Synthesis — each with its own characteristics and advantages.
