Field of invention:
The idea in technical textiles is to develop the acoustic panel by using cork and -wool fibers
compressed with a heat setting for better soundproofing. The resource is highly available in all areas.
BAKGROUND OF ART:

• Acoustic panels are made up of cork and wool fibers, our idea is about soundproof
panels.
• The primary idea is natural resources, cork is highly soundproof.

coThe cork and wool fibers are made panels by compression by heat setting and the epoxy
resin binds the wool fibers with cork formation for acoustic panel development,It will act as
high sound ABSORBANCY material from the naturally available source of cork and wool by set using
epoxy resin.
• Compactness of structure and arrangement of structures can be utilized to customize its sound
barrier and absorption behavior.
• Noise is any unwanted and unpleasant sound and underrated health hazard.

Introduction:
Acoustic comfort is critical in shaping the quality of indoor and outdoor environments,
impacting occupant well-being and productivity. Controlling sound reflections,
transmissions, and absorptions has gotten a lot of attention in a variety of situations, from
homes and workplaces to auditoriums and industrial sites. As society embraces
sustainability and environmentally sensitive activities, there is an increasing demand for
acoustic materials that not only improve sound performance but also accord with environmental
concerns.

This study aims to investigate the development and characterization of natural fibe
composite materials with a focus on cork and Mineral Wool with sugarcane bagasse fo
acoustic applications in response to this need. Because of their intrinsic qualities,
thes materials hold promising options for sound absorption and insulation. The purpose of
thi research is to thoroughly evaluate the acoustic potential, environmental impact, and
practica feasibility of incorporating cork and Mineral Wool with sugarcane bagasse composites int
various acoustic co-efficient.

Acoustic Materials and Applications:

Acoustic materials are used to control sound transmission and reflection, addressing
noise-related challenges in various sectors. In construction, they enhance the acoustic
quality of buildings and reduce external noise penetration. In the automotive and aork Fiber Properties:
Cork is a versatile natural material extracted from the bark of cork oak trees. It possesse

emarkable compressibility, elasticity, low density, and thermal insulation properties. Cork'

nique cellular structure, consisting of enclosed air-filled pores, contributes to its sour1d-
bsorbing c pabilities.. Studies have shown that cork-based_ materials exhibit promisin ound
absorption characteristics due to the complex interactions between sound waves and he porous
structure. Natural fibers, derived from plant sources, offer several advantage ver
traditional synthetic fibers, including renewable sourcing, biodegradability, and lower nergy
consumption during production. They have been extensively researched for tructural
and non-structural applications. Natural fiber composites are formed by ombining
fibers with a polymer matrix, yielding materials with desirable' mechanical and hermal
prope1iies.
