SOUND REFLECTING PANEL

SOUND PANEL• DIFFUSERS REFLECT THE ENERGY BACK

INTO THE ROOM.

• THIS ELIMINATES ACOUSTIC GLARE AND

GIVES THE IMPRESSION OF BEING IN A

LARGER, MORE NATURAL ENVIRONMENT.

• SOUND ARRIVES AS A WAVE FRONT AND

ENTERS THE DIFFUSER’S PHASE GRID

WHERE IT WILL BE REFLECTED BACK

INTO THE ROOM.

• SINCE THE WELLS ARE OF VARYING

DEPTHS, THE ENERGY EXITS AT

DIFFERENT TIMES RELATIVE TO EACH

OTHER.

THE FLOORING ACTS AS AN ABSORBING MATERIAL
