title = "Effect of Alkali Treatment and Particle Size on Sound Absorption Coefficient of Particleboards Made from Oil Palm Frond",
abstract = "This study uses an experimental approach to illustrate the significance of particle size and alkali-treated on the sound absorption coefficient of oil palm frond (OPF) particleboard. Two variables were investigated: Particle size and one hour of NaOH treatment of oil palm frond. The particleboard was manufactured based on OPF material with 10% urea-formaldehyde as the binder and 1% NHCl4 as the hardener. The mixing of OPF with UF was pressed under hot-pressing of 9 tons at 140°C for 5 minutes to obtain OPF particleboard. 100 mm and 29 mm diameter of OPF particleboard were fabricated with three different particle sizes in the constant density of 0.4 g/cm3 and thickness of 10mm. Three particle sizes were fine, medium, and coarse particle sizes with a diameter of 0.2-0.6, 1-2, 2.4-4.8 mm, respectively. The SAC was determined using a two-microphone impedance tube following ASTM E 1050 at frequencies 50 to 6400 Hz. The single rate number, noise reduction coefficient (NRC), the mean of arithmetical values for the SAC at four-octave bands frequency (250, 500, 1000, and 2000), was determined. The data from experimental and calculation were obtained and investigated.",
