Patent ID: 8083023

Claim:
A booth adapted to be positioned upon a substantially flat floor surface and adapted to confine and acoustically isolate musical drum instruments and musicians therefor, said booth comprising a rear wall, front wall assembly comprised of a number of vertically oriented plastic windows releasably interconnected in a polygonal path, and a ceiling member horizontally emplaced upon said rear wall and front wall assembly to define therewith an enclosed space, said windows being supported by pedestal blocks, said rear wall, ceiling member, and pedestal blocks being fabricated of substantially rigid fabric-covered sound-absorbing bonded rockwool structure having a density in the range of 5 to 9 pounds per cubic foot and a compressive modulus of 200 to 400 pounds per square foot at 10% compression, said pedestal blocks having a thickness of 4-5 inches, a flat upper surface having a trough which seats the lower edge of an associated window, and opposed vertical edge surfaces convergently angled toward the interior of said booth, thereby producing a trapezoidal configuration which permits sequential tight-fitting abutment of a number of said blocks upon a flat floor in a polygonal path, said blocks permitting passage thereunder of electric cables without impairing the acoustic isolation efficiency of the booth.
