Abstract

Penelitian ini dilakukan untuk menentukan karakteristik koefisien absorbsi bunyi dan impedansi akustik dari material berongga plafon polivinil klorida (PVC) yang bermerek Shunda Plafon dengan sisi tampang lintang rongga yaitu : 5, 6, 7, 8, dan 9 mm menggunakan metode tabung impedansi. Rentang frekuensi yang digunakan adalah 1000, 2000, 4000, 8000, dan 16000 Hz. Hasil penelitian menunjukan bahwa material Shunda Plafon dengan sisi tampang lintang rongga 5 mm sampai 9 mm dapat dikategorikan sebagai bahan penyerap bunyi yang cukup baik karena memiliki nilai koefisien absorbsi bunyi terendah lebih besar dari 0.15. Koefisien absorbsi bunyi dan impedansi tertinggi yaitu 0.84 dan 0,97 +  i 0,07, terdapat pada material Shunda Plafon dengan sisi tampang lintang rongga 9 mm pada frekuensi 1000 Hz. Dengan demikian material akustik terbaik dari penelitian ini adalah Shunda Plafon dengan sisi tampang lintang rongga 9 mm. Namun penggunaan Shunda Plafon untuk penyerapan bunyi dapat disesuaikan dengan tingkat frekuensi kebisingan yang akan diserap. Shunda Plafon dengan sisi tampang lintang rongga 5 mm menunjukkan penyerapan bunyi yang cukup baik karena memiliki koefisien absorbsi bunyi besar dari 0.15.
