Sound absorbing material or acoustic material is a special material made for absorbing sound at a certain frequency. Materials that are soft, porous, and fibrous are believed to be able to absorb sound energy. Banana midrib and water hyacinth are examples of natural materials with porous characteristics, which used as sound absorbent materials in this study. This experiment uses the impedance tube method, with sound intensity measurements varied from level 1 to level 5 at frequencies of 200 Hz, 400 Hz, 600 Hz, and 800 Hz. Based on the results of the absorption coefficient values, banana midrib has the highest absorption coefficient at a frequency of 800 Hz, while water hyacinth has the highest absorption coefficient at a frequency of 600 Hz. Based on the results, the banana midrib is more effective than water hyacinth, as a natural acoustic material.","PeriodicalId":82301,"journal":{"name":"Phi Kappa Phi journal","volume":"32 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81052719","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
