摘要针对现有声子晶体模型难以在结构传播与空气传播双通路实现噪声抑制的问题，文章提出了一种双层反对称阻尼式声子晶体结构，以双层阻尼式声子晶体为单元抑制噪声结构传播，将迷宫型散射体反对称式排列抑制噪声空气传播，实现双通路宽频带降噪。研究基于有限元理论与力声类比法对模型的能带图、传递曲线与吸声系数进行计算，对比分析了吸声性能与传统结构的差异，并通过实验进行验证。研究发现，模型中的双层阻尼—散射体结构可将降噪带宽拓展为传统结构的3.3倍，且同体积附加质量仅为传统结构的53.3%，反对称结构可突破吸声系数瓶颈，实现高效吸声。结果表明该模型可以实现双通道宽频带范围内的噪声控制，并具有轻质化的特点，能很好地补足现有声子晶体模型在宽频带噪声控制领域的短板。

Abstract：The paper proposes a solution to the problem of insufficient noise reduction bandwidth in both structural and air propagation pathways, which cannot be applied to existing engineering equipment with wide band sound radiation. A double-layer anti-symmetric damping phononic crystal is introduced in this paper, with the double-layer damping phononic crystals as the unit cell, and two identical unit cells are arranged in antisymmetric manner to achieve a weak coupling effect while controlling the transmission of forward and backward sound waves to improve noise reduction. The finite element method and force-sound analogy method are used to calculate the energy band diagram, transmission curve and sound absorption coefficient of this structure, and comparative analyses are carried out on the differences in sound absorption performance between the proposed structure and traditional structure. Then the results are validated through experiments. Results show that the double-layer anti-symmetric damping phononic crystal effectively controls structural noise, the noise reduction bandwidth is expanded to 3.3 times that of traditional structures, with the additional mass of only 53.3% compared to traditional phononic crystals while maintaining the same volume. For the noise transmission through the air, the anti-symmetric structure shows excellent noise reduction performance by achieving a high sound absorption coefficient. The results indicate that this model can realize dual channel noise control over a wide frequency range and has the advantage of lightweight, which effectively supplement the shortcomings in broadband noise control in existing models.

Key words： Phononic crystal Dual channel noise reduction Broadband noise reduction Noise suppression
