Penentuan Tingkat Penyerapan Bunyi Batang Pisang Yang Berbeda Jenis Menggunakan Tabung Impedansi

---

Research has been conducted in order to determine sound absorption level from banana stem at different types as A1 (core banana of barangan), A2 (core banana of sweet), A3 (core banana of stone), A4 (The third mixture of core banana ) using the impedance tube is made of glass with size of 92 cm x 20 cm x 20 cm. Banana stem was used to processed into a square with size of 20 cm x 20 cm, the thickness of samples is 5 mm. Sound was source producted a loudspeaker with range of frequencies Hz, 250 Hz, 500 Hz, 1000 Hz, 2000 Hz, 4000 Hz. Samples was prepared by carrying out a comparison of Banana stems : corbstarch like 90 % : 10 %. Result showed that the biggest coefficient absorbtion value of sample A2 (core banana of sweet) was 0,58117 at frequency of 250 Hz while the value of low absorption coefficient in samples A3 (core banana of stone ) was 0.27631 at frequency of 125 Hz .
Keywords : Absorption of sound, banana stems, impedance tube, frequency
