The Development of Acoustic Screeing Device Made From Used Paper Material

Abstract

This quisi-experimental research aims to study the performance of acoustic screeing panels made from used papers and the invention of acoustic screeing panels. Thisacoustic screeing panelswas performed by measuring noise level. Data was analyzed with descriptive statistics. Results, the noise frequency of 50 Hz, volume level was at 4.3 dB(A) which means the noise absorbed panel can reduce noise level by 93 %, the frequency of 100 Hz the volume was at 7.0 dB(A) which means the noise absorbed panel can reduce noise by 90 %, the frequency of 150 Hz the volume level was at 11.2 dB(A) which means the noise absorbed panel can reduce noise level by 86 %, the frequency of 200 Hz the volume level was at 14.5 dB(A) which means the noise absorbed panel can reduce noise level by 83 %, and the frequency of 250 the volume level was at 13.2 dB(A) which means the noise absorbed panel can reduce noise level by 84 %. However, at the frequency of 300 Hz noise panels absorb panel cannot absorb noise. Base on this research the method of forming or structuring noise absorbed panel must be improved.
