Abstract

Noise (unwanted sound) is a kind of pollution that hits public community in many cities and industrial areas, harms human health both physically and psychologically. The aim of the study is producing an acoustical composite as building material component for absorbing noise. The method was conducted by synthesizing and characterizing two kinds of samples: the first was made of crushed Pumice and Aluminium Oxide (Al) by mechanical mixing with Polyvinyl Acetate (PVAc) as binder without resonator, and the second was equipped by Quarter Wavelength and Helmholtz Resonators. The Physical and Chemical Properties of each sample has been characterized by EDAC, FTIR, XRD, SEM, Universal Testing Machine and Impedance Tube. The experiment results show that the composite of pumice and Aluminum Oxyde with PVAc as binder has high strength, waterproof and fire resistant. It so happens the value of absorbtion coefficient () of produced composite without resonator below 0,12 at all measured frequency area. The similar composite that equipped by Quarter Wavelength Resonator has value about 0,28 at frequency range between 1000 Hz – 4500 Hz, while the composite that equipped by Helmholtz Resonator inside the synthesized composite has value about 0,9, it effectively absorbs noise especially at low frequency areas below 1000 Hz. It is concluded that the tested composite which equipped by resonator is a good alternative as a building material component for noise absorber at low and medium frequencies areas because low in cost and easy to produce.
