Intellectual Property India Publishes Patent Application for A Multi-Modal Combinatorial System And Predictive Permutation Method For Contactless And Sensor Less Open-Air Active Acoustic Attenuation Of Upper-Airway Vibrations.

MUMBAI, India, Sept. 28 -- Intellectual Property India has published a patent application (202641088066 A) filed by I. G. Sriram Pardha Varma on July 19, 2026, for A Multi-Modal Combinatorial System And Predictive Permutation Method For Contactless And Sensor Less Open-Air Active Acoustic Attenuation Of Upper-Airway Vibrations..

Inventor includes I. G. Sriram Pardha Varma.

The application for the patent was published on September 25, 2026, under issue no. 39/2026.

Abstract: ABSTRACT: Title: AMBIENT ELECTRO-ACOUSTIC WAVE MODULATION AND DYNAMIC SPATIAL WAVEFORM PHASE-INVERSION SYSTEM An open-air electro-acoustic wave modulation system for contactless active mitigation of upper-airway tissue resonances within an airspace manifold is disclosed. The system comprises a stationary chassis housing a contactless FMCW mmWave radar matrix, a distributed digital MEMS microphone input array, a spatial audio projector engine, an asymmetric mechanical decoupling framework, and a centralized monolithic processing layer. The processing layer executes a synchronous dual- sensor matching loop that extracts a respiration vector from radar reflections and cross-references acoustic envelopes to verify a validation threshold. Upon verification, the processor utilizes an adaptive control loop and a power-damping clamp to inject a 180-degree phase-inverted anti-noise wave into targeted spatial coordinates centered over a listener’s ear canal, suppressing airborne sound amplitude in real-time. A physical galvanic disconnect switch isolates microphone power rails for hardware-level privacy.
