ACOUSTICAL TREATMENT

Quality acoustics depend on a carefully engineered combination of sound absorption and diffusion. Materials such as thick, fibrous panels absorb sound, which reduces loudness and controls reverberation. Large, reflective irregular surfaces will diffuse sound and improve communication among ensemble members and the director. Suspended ceilings of absorptive panels are also quite effective at broad-frequency musical absorption. By studying each individual room and determining the proper combination and placement of absorptive and diffusive panels, a wide variety of acoustical shortcomings can be effectively treated.

UNTREATED ROOM Low frequencies are overpowering, reverberant and indistinct.

ROOM TREATED WITH ABSORBER PANELS ONLY Loudness is reduced but lack of reflective surfaces has negative impact on timbre which causes forced singing and overblowing.

ACOUSTICALLY BALANCED ROOM WITH ABSORBER AND DIFFUSER PANELS Loudness is controlled. Performers can hear themselves and each other. Conductor has accurate impression of balance.
