This review presents a structured analysis of 54 studies on AMMs for duct acoustics, with civil, mechanical, aerospace, and biomedical engineering applications. AMM unit designs are categorized by physical mechanism, including resonant cavities, acoustic membranes, Herschel\u2013Quincke tubes, Fano-like interference structures, duct shape modifications, micro-perforated panels, and porous materials. The associated acoustic and flow-related performance parameters, such as insertion loss, transmission loss, absorption coefficient, flow velocity, temperature, pressure drop, Reynolds number, and Mach number, are systematically examined. Analytical, numerical, and experimental approaches are reviewed with attention to their respective merits and limitations, particularly in capturing multi-physical interactions between acoustics, fluid flow, and structural dynamics. Of the studies surveyed, 35 employed monophysical models, 8 used loosely coupled (monophysical parallel) methods, and only 11 adopted fully coupled multi-physical frameworks. This review highlights the need for integrated design methodologies and standardized evaluation under realistic flow conditions to advance the effective implementation of AMMs in ducted acoustic systems.<\/jats:p>","DOI":"10.1121\/10.0041769","type":"journal-article","created":{"date-parts":[[2025,12,10]],"date-time":"2025-12-10T16:11:04Z","timestamp":1765383064000},"page":"4560-4581","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":12,"title":["Review of metamaterials principles and methods in ventilation ducts: 1928\u20132024"],"prefix":"10.1121","volume":"158","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4695-6430","authenticated-orcid":false,"given":"Gioia","family":"Fusaro","sequence":"first","affiliation":[{"name":"Department of Industrial Engineering, University of Bologna , Bologna 40136,","place":["Italy"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dario","family":"D'Orazio","sequence":"additional","affiliation":[{"name":"Department of Industrial Engineering, University of Bologna , Bologna 40136,","place":["Italy"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8708-2314","authenticated-orcid":false,"given":"Massimo","family":"Garai","sequence":"additional","affiliation":[{"name":"Department of Industrial Engineering, University of Bologna , Bologna 40136,","place":["Italy"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"231","published-online":{"date-parts":[[2025,12,10]]},"reference":[{"key":"2026052709560650000_c1","doi-asserted-by":"publisher","first-page":"106594","DOI":"10.1016\/j.ijmecsci.2021.106594","article-title":"Metamaterial-based muffler with broadband tunability in a limited space: Optimal design, theoretical investigation and experiment","volume":"205","year":"2021","journal-title":"Int.
