Duabanga moluccana cross sectional specimens were analyzed to gas permeability, pore size, and open-pore porosity and also measured its sound absorption coefficients with an impedance tube. Duabanga moluccana showed a larger pore size and greater open-pore porosity than other hardwood species, and its sound absorbing performance was superior to that of the gypsum board currently used as a commercial ceiling material. Although this was a laboratory-scale investigation, we demonstrate that Duabanga moluccana cross sections have potential as a natural sound absorbing functional building material.<\/p>\n","protected":false},"author":5,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[4024],"tags":[4109,4107,4106,4108],"release_year":[],"ppma_author":[3898,3899],"class_list":["post-4325","post","type-post","status-publish","format-standard","hentry","category-wood-research-volume-67-number-4-2022","tag-duabanga-moluccana","tag-eco-friendly-materials","tag-open-pore-porosity","tag-sound-absorbing-performance"],"featured_image_src":null,"author_info":{"display_name":"Stela Sl\u00e1mov\u00e1","author_link":"https:\/\/www.woodresearch.sk\/cms\/author\/slamovavupc-sk\/"},"authors":[{"term_id":3898,"user_id":0,"is_guest":1,"slug":"eun-suk-jang","display_name":"EUN-SUK JANG","avatar_url":"https:\/\/secure.gravatar.com\/avatar\/?s=96&d=mm&r=g","0":null,"1":"","2":"","3":"","4":"","5":"","6":"","7":"","8":""},{"term_id":3899,"user_id":0,"is_guest":1,"slug":"chun-won-kang","display_name":"CHUN-WON KANG","avatar_url":"https:\/\/secure.gravatar.com\/avatar\/?s=96&d=mm&r=g","0":null,"1":"","2":"","3":"","4":"","5":"","6":"","7":"","8":""}],"_links":{"self":[{"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/posts\/4325","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/users\/5"}],"replies":[{"embeddable":true,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/comments?post=4325"}],"version-history":[{"count":2,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/posts\/4325\/revisions"}],"predecessor-version":[{"id":4347,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/posts\/4325\/revisions\/4347"}],"wp:attachment":[{"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/media?parent=4325"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/categories?post=4325"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/tags?post=4325"},{"taxonomy":"release_year","embeddable":true,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/release_year?post=4325"},{"taxonomy":"author","embeddable":true,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/ppma_author?post=4325"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
