MUMBAI, India, Feb. 6 -- Intellectual Property India has published a patent application (202541084684 A) filed by Chaitanya Bharathi Institute Of Technology, Hyderabad, Telangana, on Sept. 6, 2025, for 'areca nut fiber reinforced composite boards for enhanced acoustic insulation.'
Inventor(s) include Kiran Kumar Amireddy; Paleti Satatha; B Shravan Kumar; and D Sri Harsha.
The application for the patent was published on Feb. 6, under issue no. 06/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a composite board for acoustic insulation, comprising areca nut natural fibers reinforced within a polymeric resin matrix. The inventive board is a single-medium structure that provides broadband acoustic insulation across low and high frequencies, without reliance on perforations, porous structures, or multi-layered assemblies common in the prior art. The areca nut fiber composite exhibits enhanced sound absorption and dampening properties while maintaining superior structural integrity and dimensional stability. Fabricated via a simple and cost-effective hand lay-up process, the invention utilizes an abundant agricultural by-product to provide an environmentally sustainable and biodegradable alternative to conventional synthetic and mineral-based acoustic materials, offering 2-3 times higher performance at higher frequencies ( 4000 Hz) compared to other agricultural fiber-based boards."
