Abstract
This study investigates the potential of natural fibers—such as sawdust, jute, pineapple, and
coconut fibers—as sustainable sound absorbers, addressing the environmental concerns
associated with conventional synthetic materials. Traditional sound-absorbing materials often
contain artificial, non-biodegradable components that negatively impact the environment. In
contrast, natural fibers are renewable and biodegradable, making them a promising alternative.
The research focuses on the acoustic characteristics of natural fibers, evaluating their ability
to attenuate sound waves at various frequencies. Through rigorous experimental procedures,
including specialized equipment and acoustic testing chambers, the study assesses the
absorption coefficients and other relevant properties of these fibers. It also examines the
effects of different material compositions, surface treatments, compression, and fiber
processing methods on acoustic performance.
The research findings unequivocally showcase the remarkable sound-absorbing attributes of
natural fibers, particularly within the mid to high-frequency spectrum. Their innate porosity
and intricate fibrous composition play a pivotal role in efficiently dissipating sound energy.
This underscores the compelling potential of natural fibers as sustainable alternatives for
sound absorption applications. By leveraging these materials, there exists a dual advantage:
mitigating environmental impact through the use of renewable resources while simultaneously
achieving superior acoustic performance. This paradigm not only addresses the pressing need
for eco-friendly solutions in acoustic management but also aligns with broader sustainability
goals across industries. Embracing natural fibers in this context represents a significant stride
towards enhancing environmental stewardship and advancing sound control technologies for
a more harmonious and sustainable future.
By delving into the capabilities of natural fibers for acoustic applications, this study provides
valuable insights into harnessing biodegradable and environmentally friendly materials. The
findings advocate for the integration of sustainable materials across diverse sectors, including
construction and automotive industries, thereby advancing a greener approach to acoustic
management. This initiative resonates with the growing call for ecologically sound
alternatives, aiming to mitigate the impact of sound pollution on both the environment and
human health
