摘要: Acoustic resonators are formed by injection molding or other process that allows the shape, size, orientation, and arrangement of each resonator to be customized. Customizing features their resonance frequency adjusted based on intended deployment. A non-periodic non-uniform can increase level noise reduction compared a periodic uniform resonators. chain guard includes recess receive supports plurality rows frames. In stowed configuration, pivots towards row/frame more compactly stow panel
