Natural fibres are low cost, low density, high specific properties, non-abrasive, and biodegradable. Empty Fruit Bunch (EFB) can be directly derived from natural resources; it is inexpensive and also has advantages due to its, organic nature, low cost, and easy viabilities. This research has been carried out to study the acoustic performance of EFB, which has a high potential to be used for sound insulation material. The effect of various types of EFB (short strand and fined) was investigated with 180 kg/ density in four different thicknesses (12 mm, 14 mm, 16 mm, and 18 mm). Samples were carried out using the Impedance Tube Method (ITM) consistent with international standard, ASTM E1050-98 used for measuring the sound absorbing coefficients (SAC). Results show that the SAC value increases with an increase in thickness for all samples. Maximum absorption for short strand fibre samples obtained by thickness of 14 mm with SAC value of 0.97 at 4604 Hz while for fined fibre; the maximum absorption was also obtained by thickness of 14 mm with SAC value of 0.93 at 3842 Hz. The result indicates that short strand fibre absorbed more sound energy at high frequency region compared to fined fibre. Overall comparison, the optimal sound absorption coefficient was obtained from short strand fibre which absorbed better sound energy with a wider frequency range. In conclusion, this research has successfully defined that EFB is viable to be used as raw fibre for acoustic absorber. 2023-05-03T15:00:47Z 2023-05-03T15:00:47Z 2020-09 https://irepository.uniten.edu.my/handle/123456789/20433 application/pdf |
