| Abstract | The structure of a cavity is broadly applied in passive noise absorbers to adjust the inlet
reatance, which is a key factor affecting the sound absorption performance of the absorbers.
The performance of cavity in reactance adjusting is mainly limited by its volume. Large
volume is needed to lower the resonance for excellent low-frequency noise absorption. This
work introduces a potential method to adjust the reatance for better low-frequency
performance by cavity design when the volume is fixed. The effect of cavity shape on the
cavity’s inlet reactance is investigated with a 2D finite element model, and the corresponding
mechanism is explained. In addition, the acoustic property of two parallel irregular cavities is
investigated to study the inter-resonator interaction. |
