Redefining Noise Control: The Science and Engineering of Acoustic Metamaterials
For decades, noise control has relied on traditional methods—thicker walls, dense foams, and fibrous liners. These solutions work for mid- and high-frequency noise but struggle against low-frequency sounds below 300 Hz, such as industrial hums or HVAC tones. Blocking these frequencies typically requires bulky materials over 150 mm thick, which is impractical for compact machines, […]
