Abstract

Telah dilakukan pengujian karakteristk akustik dari material ampas tahu. Material tersebut merupakan material alternatif penyerap bunyi. Pengujian dilakukan dengan menggunakan metode tabung. Hasil pengujian menunjukkan bahwa material serat alam yang dicampur dengan lem memilki nilai koefisien absorbsi bunyi yang baik pada rentang frekuensi 1000-8000 Hz. Nilai koefisien absorbsi bunyi yang tinggi dimilki oleh material dengan pori-pori yang lebih besar (0,90 - 0,99). Selain koefisien absorbsi juga dilakukan pengujian nilai impedansi akustik. Hasilnya Menunjukkan bahwa perbandingan massa lem dengan ampas tahu diperoleh nilai impedansi yang baik (7,75 dan 8,33).
