Abstract

Penelitian ini membahas tentang pengujian diffuser dengan menggunakan
kayu-kayu yang berbeda (kayu tripleks meranti, kayu jati, dan kayu kamper). Tujuan
pengujian ini adalah untuk memudahkan insinyur akustik memilih kayu yang akan
digunakan sebagai diffuser dalam perancangan tata suara auditorium. Pengujian dilakukan
dengan metode boundary plane measurement yang merujuk pada AES-4id-2001. Hasil
pengujian diperoleh grafik respon polar dan koefisien difusi dengan frekuensi 800 Hz,
1000 Hz, dan 1250 Hz. Berdasarkan pengujian tersebut, kayu kamper merupakan kayu
yang terbaik untuk dijadikan diffuser.
