The hard surfaces of traditional baffles are useful for redirecting and restraining (aka, “baffling”) the flow of sound energy, but they’re quite poor at absorbing sound energy. Even baffles that claim to absorb sound —such as felt, fabric and foam— are surprisingly ineffective, demonstrating notorious discrepancies between their performance in laboratory tests and their performance in actual, real-world installations. Cella Acoustic Baffles provide such excellent performance; just one side of a Cella baffle is more sound absorbent than an entire felt, foam, or metal acoustic baffle.
