Kinerja Serapan Bunyi Komposit Ampas Tebu Berdasarkan Variasi Ketebalan dan Jumlah Quarter Wavelength Resonator terhadap Kinerja Bunyi
Abstract
Dalam penelitian ini dilakukan variasi tiga dan enam konfigurasi resonator serta variasi air cavity yakni 1, 2, dan 3 cm. Hasil penelitian menunjukkan bahwa komposit ampas tebu dengan konfigurasi enam resonator memiliki kinerja serapan bunyi terbaik. Adapun pengaruh ketebalan sampel adalah menggeser penyerapan bunyi efektif pada frekuensi rendah sementara penggunaan resonator efektif akan melebarkan rentang frekuensi penyerapan sehubungan dengan bertambahnya mekanisme redaman viskous bersamaan dengan mekanisme
serapan resonasi.
