MUMBAI, India, Feb. 27 -- Intellectual Property India has published a patent application (202541133436 A) filed by Rajalakshmi Engineering College, Chennai, Tamil Nadu, on Dec. 30, 2025, for 'non-airflow aerophone and human interaction system using continuous acoustic impulse response control.'
Inventor(s) include Dr. M. Thangamani; V. Govarthan; and B. Dinesh.
The application for the patent was published on Feb. 27, under issue no. 09/2026.
According to the abstract released by the Intellectual Property India: "Unlike conventional aerophone instruments requiring airflow, pressure sensmg, or reed 220 excitation, this invention derives continuous expressive control solely from dynamic impulse response estimation of acoustic cavities using inaudible or perceptually masked probing signals. Finite-length chirp signals with delta-like autocorrelation are injected into the cavity; responses are captured, windowed under linear time-invariant approximation, and converted into high-dimensional impulse response estimates encoding human-induced geometry changes. These estimates function 225 as primary control states for real-time audio synthesis or digital control without airflow measurement or intentional audible output, enabling musical performance and human interaction applications."
