The BAD Panel is the ultimate synergy of advanced acoustical technology and simplicity of design for when performance is paramount but budgets are modest. Using an optimal binary pattern of perforations through a Class A fire rated rigid template, the BAD Panel achieves an excellent balance of sound absorption across the NRC frequency bands while preserving the ambience of the space. In all, this unique surface eliminates excessive high frequency absorption, transitions to a scattering surface in the very high frequencies, prevents lobing inherent in common perforated surfaces and significantly improves mid and low frequency absorption.
