Our Tuned Absorber/Diffuser Panel combines superior acoustical characteristics and a choice of fabric or vinyl coverings to give you the best design solution for areas where more balanced sound absorption and high frequency diffusion are desirable.
Place
the Tuned Absorber/Diffuser where low and mid-frequency absorption is desired
in conjunction with increasing reflectivity and diffusion in higher frequencies.
The outstanding acoustical performance of this panel is the result of the
assembly of a sound absorptive fibrous core covered with a variable impedance
laminate. Openings in the laminate are sized and spaced to optimize the
absorption in lower frequencies while creating random mid and high frequency
reflective surfaces between openings (variable impedance). A design program
is utilized to acoustically optimize the hole pattern in the laminate while
maintaining the desired overall open versus reflective area in the panel
surface. For increased low frequency sound absorption, a thicker fibrous
core (2 to 4 inches) can be specified. For increased high frequency absorption,
the hole size can be changed to 5/8 inch diameter versus the standard 1/2
inch opening.
