AMF SOUNDMOSAIC
GENERAL INFORMATION
The newly developed AMF SOUNDMOSAIC is a flat-panel (membrane) loudspeaker in
modular ceiling format and works on the principle of wave conversion. As such, the mineral
fibre ceiling tile itself works as the loudspeaker, the stimulation (oscillation) is effected by the
SOUNDMODULE on the reverse of the tile which therefore does not differ optically from the
rest of the AMF ceiling. As a result the AMF SOUNDMOSAIC is available in all classic
THERMATEX surfaces.
AMF SOUNDMOSAIC
One main component is the SOUNDMODULE,
which
as
the
simultaneously constitutes the most important
element of the component assembly. To
optimize the effect of the surface-emitted
sound, the adjoining tiles are integrated and
linked to each other by common ceiling tile
clips.
DESCRIPTION OF ASSEMBLY
The
mechanical
SOUNDMOSAIC is like that of any AMF mineral
fibre ceiling tile. For the correct installation
please refer to the installation instructions for
AMF System C. For an ideal emission of sound
we discourage its use as a perimeter tile. Its
installation should be done at least in the
second (ideally at least in the third) row from the
perimeter.
Please avoid the connecting cable resting on the
reverse of the ceiling tiles which might give rise
to unwanted vibrations.
The individual tiles are to be connected to each
other by clips (at least two clips for each tile
edge). Consequently, nine AMF ceiling tiles are
interconnected to each other in total, i.e.
besides
the
SOUNDMODULE a further eight circumferential
tiles.
Number
of
clips
SOUNDMOSAIC: at least 24 pieces.

Summary of Contents for AMF SOUNDMOSAIC
- Page 1 (oscillation) is effected by the SOUNDMODULE on the reverse of the tile which therefore does not differ optically from the rest of the AMF ceiling. As a result the AMF SOUNDMOSAIC is available in all classic THERMATEX surfaces.
- Page 2 TECHNICAL INFORMATION / INSTALLATION INSTRUCTIONS AMF SOUNDMOSAIC SPEECH INTELLIGIBILITY The required intelligibility of speech has considerable influence on the lay-out and number of loudspeakers needed. The objective is the constant intelligibility of sound and syllables also over some distance. A crucial criterion constitutes the so-called STI-Index: STI: Speech Transmission Index Measure of speech intelligibility of syllables, words and whole sentences.
- Page 3 Image 6 sound level of approximately 80 dB is sufficient for the AMF SOUNDMOSAIC to still achieve 70 dB at a distance of 8 meters; i.e. a drop in volume of only 10 dB. In comparison: A common conical loudspeaker requires a source sound level of about 90 dB for the same effect.
- Page 4 (loud) near the loudspeaker or as too low (quiet) at some distance. Interference for individual frequencies as it is customary with conical loudspeakers through the interaction of sound waves does not occur with the AMF SOUNDMOSAIC due to its special technology.
- Page 5 ADDITIONAL WEIGHT LOADS Due to its low weight the AMF SOUNDMOSAIC can be installed in any new or existing ceiling without special considerations (see “LAY-OUT” above for details). It is not necessary to provide for additional suspension hangers for standard ceilings.
- Page 6 Using this value in customary planning tools the conduct of sound emission buy the AMF SOUNDMOSAIC cannot be correctly simulated. SCOPE OF DELIVERY When ordering an AMF SOUNDMOSAIC you will receive the individual components that are required for installation on site.
