Abstract

The recent paper “Sound Transmission Performance of Plate-Type Acoustic Metamaterials for Quieter Aircraft Cabins” (Applied Acoustics 238 (2025) 110806) investigates acoustic metamaterials for cabin noise reduction. However, several critical issues affect the validity of its conclusions. Material properties are inconsistent and sometimes incorrect and differ between simulations and experiments, undermining the validity of comparisons. The choice of the unit cell configuration as “optimal” is based solely on eigen frequency stability, without providing direct evidence of improvements in sound pressure level or sound transmission loss. Moreover, simulations apply force excitation while experiments use acoustic excitation, preventing reliable validation. Finally, several references cited cannot be retrieved from standard databases, raising concerns about their authenticity. This note highlights these issues and calls for clarification.

对“飞机机舱静音用板式声学超材料的传声性能”的评论[j]。声学学报，238 (2025)110806 [j]

最近的一篇论文“用于更安静飞机客舱的板式声学超材料的传声性能”（应用声学238(2025)110806）研究了用于客舱降噪的声学超材料。然而，几个关键问题影响其结论的有效性。材料性质不一致，有时不正确，模拟和实验之间的差异，破坏了比较的有效性。选择单元格配置作为“最佳”配置仅仅是基于特征频率稳定性，而没有提供声压级或声音传输损失改善的直接证据。此外，模拟采用力激励，而实验采用声激励，妨碍了可靠的验证。最后，引用的一些参考文献无法从标准数据库中检索，这引起了对其真实性的担忧。本说明强调了这些问题，并要求澄清。

期刊介绍： Since its launch in 1968, Applied Acoustics has been publishing high quality research papers providing state-of-the-art coverage of research findings for engineers and scientists involved in applications of acoustics in the widest sense. Applied Acoustics looks not only at recent developments in the understanding of acoustics but also at ways of exploiting that understanding. The Journal aims to encourage the exchange of practical experience through publication and in so doing creates a fund of technological information that can be used for solving related problems. The presentation of information in graphical or tabular form is especially encouraged. If a report of a mathematical development is a necessary part of a paper it is important to ensure that it is there only as an integral part of a practical solution to a problem and is supported by data. Applied Acoustics encourages the exchange of practical experience in the following ways: • Complete Papers • Short Technical Notes • Review Articles; and thereby provides a wealth of technological information that can be used to solve related problems. Manuscripts that address all fields of applications of acoustics ranging from medicine and NDT to the environment and buildings are welcome.
