Typical
installation
The only place available in most classrooms is above the blackboard.
However, more is better.
Mounting
methods
The FlatPanel can be flush-mounted or picture frame-mounted,
angled downward.
How the FlatPanel
works
The "hotspot" in any
room is at the corners where the wall meets the ceiling or
wall meets wall. These produce the most common acoustic flaws
that can limit speech intelligibility.
(top view)
Attenuation dampens teacher's vertical
resonance and reduces front to back reflection path.
Lateral sound from teacher is dampened.
Early reflection is allowed.
Attenuation on back wall dampens sound
once it is heard by students.
(Side view)
Side walls and ceiling are reflective
- lots of reflective surfaces provide early reflections
to improve strength of direct signal.
Backward moving vertical sound dampened
out by upper panels.
(Front view)
Upward sound absorbed by panels.
Downward sound absorbed by students and
carpet.
Minimum System:
Carpet reduces classroom desk noise.
Panels to each side of teacher eliminates
side to side storage of sound that blocks speech.
Panels behind teacher control vertical
resonance and dampen front to back reflections.
Panels on back wall dampen back to front
reflections.
Lateral circulation of sound in classroom
area is controlled by carpeted floor.
Upper side walls left bare to enhance
early reflections of teacher's voice.
