MUMBAI, India, Jan. 9 -- Intellectual Property India has published a patent application (202511113461 A) filed by K. R. Mangalam University, Gurugram, Haryana, on Nov. 18, 2025, for 'portable tabletop dual-loop active noise cancelation acoustic shield for home workspaces.'
Inventor(s) include Dr. Tanaya Verma.
The application for the patent was published on Jan. 9, under issue no. 02/2026.
According to the abstract released by the Intellectual Property India: "The invention provides a portable acoustic shielding system in the field of noise control, featuring a fold-flat three-panel enclosure with a rigid outer skin, a 25-mm open-cell foam core, and an outer PET-felt layer, joined by precision magnetic joints and calibrated hinge assemblies that form a U-shaped semi-sealed acoustic volume with gap tolerances under 2 mm. It incorporates a dual-loop active noise cancellation module utilizing an inbound loop with external MEMS microphones and an outbound loop with an internal microphone, interfaced with a DSP board based on a 150 MHz ARM Cortex-M7 processor executing adaptive feed-forward and feedback filtering algorithms to generate anti-phase sound waves in less than 500 s. Internal and external loudspeaker assemblies, integrated wiring conduits, and a user interface module enable selectable operational modes for enhanced acoustic performance."
