Analisis Kinerja Akustik Panel Gedek Bambu dengan Sisipan Komposit Eceng Gondok
Abstract
sama dengan pengujian koefisien serapan bunyi. Hasil pengujian menunjukkan bahwa respon akumulatif sisipan panel berlubang dan variasi pada dimensi rongga udara dapat secata efektif meningkatkan kinerja akustik panel gedek yang diteliti hingga kisaran 0,5 hingga 0,83 dan bertahan dalam bentang frekuensi yang lebar mulai 400 Hz. Rugi transmisi berada pada kisaran (30-55 dB) dengan keteraturan respon yang mengikuti konfigurasi sampel.
