Abstract

The use of synthetic materials as acoustics absorbers is currently still widely applied in industry. These materials, in fact not only cause pollution to environment but also contribute to human health problem. This project presents a solution to find sustainable and eco-friendly materials to be an alternative sound absorber by using perforated acrylic plate as sound absorber materials. The perforated acrylic plate is fabricated and its effectiveness is determined through experiment based on ISO 10534-2 Standard. Data collected is analyzed to achieve the objectives on comparing the effectiveness in absorbing the sound energy. The result shows that the acrylic perforated panel with different size of holes gives different absorption performance in reducing sound energy. Generally, the plates are effective for reducing noise at 1500-3500Hz frequency range.
