THE MAKING AND CHARACTERIZATION OF RUBBER WOOD COMPOSITE PARTICLE AS NOISE REDUCTION MATERIAL
Keywords:
sound absorption, karet fiber, Tubes Impedance
Abstract
The purpose of this research is to find out the composition between rubber wood and
cement matrix in making composite silencer material which has the best sound
absorption at frequency 250, 500, 750 and 1000 Hz. In this research, using Arduinobased impedance arcade type impedance testing apparatus used ISO 11654 standard.
The matrix used is rubber wood particles, portland cement and water. The composite is
printed with a mass fraction (4:16, 6:14, 8:12) gram using a mold 4 cm in diameter and
14 cm in height. The test specimens were made with a diameter of 4 cm and a thickness
between 1 - 1.5 cm. The results showed that for the best absorption coefficient value
found in the mass fraction of 8 grams of particles: 12 grams of cement matrix is 0.33 with
a frequency of 750 Hz. While the lowest absorption coefficient of sound with a mass
fraction of 4 grams of particle: 16 grams of cement matrix is 0.12 with a frequency of
500Hz.
