An active noise control subassembly array for reducing noise caused by a source (such as an aircraft engine). A pair of subassemblies each has a piezoceramic-driven noise radiating panel to generate a panel noise canceling at least some of the source noise. A front plate is spaced apart from the panel and has a sound exit port. A first pair of spaced-apart side walls each generally abuts the panel and the front plate so as to generally enclose a front cavity to define a resonator. A back plate is spaced apart from the panel by a second pair of side walls...
An active noise control subassembly array for reducing source noise caused by a source independent of said array, said array comprising: a) a pair of active noise control subassemblies each including: 1) a piezoceramic-driven noise radiating panel bendably vibratable to generate a panel noise canceling at least a portion of the source noise and having a panel resonating frequency; 2) a front plate spaced apart from said panel, disposed generally between said source noise and said panel, and having a sound exit port; 3) a first pair of spaced-apart side w...
