A theoretical method based on mutual radiation impedance is proposed to compute the sound absorption performance of a Helmholtz resonator array in the low-frequency range. Any configuration of resonator arrangement can be allowed in the method, while all the resonators may or may not be identical. Comparisons of the theoretical predictions with those done by the past studies or experiments show that the present method can accurately predict the absorption performance in more general cases.
提出了一种基于互辐射阻抗的理论方法来计算亥姆霍兹共振器阵列在低频范围内的吸声性能。该方法允许共振器排列的任何配置，而所有共振器可以相同也可以不同。将理论预测结果与过去的研究或实验结果进行比较表明，该方法能够在更一般的情况下准确预测吸声性能。
