Design and development of one-dimensional acoustic bundle ventilated metamaterial
Sanjeet Kumar Singh, Om Prakash, Shantanu Bhattacharya · EDP Sciences · 2026
A one-dimensional kink-fiber acoustic meta-structured blanket is proposed and validated to enable broadband sound absorption while permitting airflow through the structure.
Plain English summary
Why this matters
Key findings
- Four one-dimensional kink-fiber metamaterial configurations are proposed: KF, YAM, CDAM, and IRAM.
- The design is subwavelength with a characteristic size of 7 cm.
- Broadband sound absorption of about one octave is reported.
- Absorption values of 0.5–0.9 are reported in the 500–1600 Hz range.
- Validation is reported via transfer matrix method, FEM, and impedance tube experiments.
Limitations
The abstract does not specify detailed tuning mechanisms, parameter ranges, durability under real airflow conditions, or performance outside the reported 500–1600 Hz band.
