“…Indonesia has an abundance of biomass fiber resources which may be processed and used in manufacturing. Since many studies observed biomass fiber applications and their acoustic characteristics [8][9][10][11][12][13][14][15][16], one of the applications in buildings is biomass fibers which are treated as sound absorbers. As far as these efforts are concerned, a study by Tang et al investigated corn husk in terms of its sound damping performance [8].…”

“…Several studies have investigated materials made of biomass fibers [10,11,17,18]. Three variables: thickness, fiber size, and polymeric content as binder, were observed by Othmani et al based on sugarcane waste material and its resistivity and sound absorption performance [10]. Like Othmani's study, research by Ismail et al also examined waste materials of coir and shredded paper from offices by investigating four samples in a reverberation chamber (refer to the ISO 354-1985 standards) [11].…”

The aim of this research is to observe the acoustic performance of absorber-based biomass fiber-reinforced polyester resins that were experimentally associated with the design of tailed cavity resonator inclusion, i.e., the cavities are partly in the form of a narrow slit. The model of electro-acoustic resonators and several treatments were developed and became the bases for understanding the changes of acoustic reactance in the new structure. Variations in the inclusion cavity and the addition of a narrow slit were tested experimentally using an impedance tube technique based on ASTM E1050-98 and ASTM E2611-09. The improvements of acoustic performance were conducted by single and multiple cavity tailed inclusions with the addition of a Dacron fibrous layer and back cavity. The experimental results showed that a sample of 15 mm single tailed cavity kenaf fiber had higher sound absorption and wider broadband frequencies than did the hemp fiber, with a peak on 0.31–0.32 between 1.00–2.00 kHz. Meanwhile on multiple tailed cavities, the 30 mm hemp fiber had higher and wider broadband frequencies than did the kenaf, with peaks on 0.45–0.63 at frequencies between 1.75–2.10 kHz. It can be concluded that the tailed cavity inclusions could improve performance. Compared to the coco-husk with resonators in previous studies, the tailed cavity was a little bit lower, but the tailed cavities hemps and kenafs samples showed good sound absorption performance with lower band frequencies capabilities.

“…As Othmani et al. [27] reported, resin content reduction in the sugarcane fiber composite raises the air flow resistivity along with the sound absorption coefficient. This is usually achieved by the higher levels of porosity in the composite that is the result of applying lower resin content.…”

The present study examines the acoustic behavior sample composites made of date palm natural fibers and polyvinyl alcohol. It also provides the comparison between the sound absorption coefficients obtained from the experimental tests and the ones predicted by the mathematical models. An impedance tube system was used to measure the normal sound absorption coefficient of the samples. Using the differential equation algorithm, the predicted sound absorption coefficient for the Johnson-Champoux-Allard model was also calculated. The sound absorption properties of samples increased significantly by increasing the frequency, and increasing the thickness of materials with constant density. Comparison of the data from the experimental tests and mathematical model showed that increasing the thickness of samples will make the predicted and tested values of acoustic absorption coefficient significantly comparable. Date palm fibers have a good potential for dissipating the energy of sound waves particularly when an air gap is introduced behind the sample and can be used as a new source for the fabrication of natural fiber reinforced composites.

“…Sansevieria cylindrica fiber was studied for its dynamic, mechanical, surface and thermal properties and the effect of alkali treatment on fiber properties and corresponding effects on the mechanical and thermal properties were analyzed [9]. Various other studies were done to characterize the properties of natural fibers, its composites and its nonwovens [1,[10][11][12][13][14][15][16].…”

The increasing concern over the waste reduction and health hazards associated with the use of synthetic fibers such as glass fibers, carbon fibers, aramides and other fibers have turned the attention towards natural ecofriendly green fibers. In this paper natural fibers namely-milkweed fiber, Agave americana fiber and Sansevieria roxburghiana fibers have been studied experimentally to determine the physical, chemical, morphological and thermal properties by FTIR, SEM, PLM, X-Ray diffraction, DSC and TGA analysis methods. In this study, Sansevieria fiber was observed to have the highest tenacity of 53.58 g/tex and showed maximum degradation temperature of 375 °C. Milkweed fibers were found to have the lowest density of 0.9 g/cc and possessed hollow structure with smooth surface as observed from SEM and PLM techniques.
