MUMBAI, India, April 17 -- Intellectual Property India has published a patent application (202531098041 A) filed by Guru Nanak Institute Of Technology, Kolkata, West Bengal, on Oct. 10, 2025, for 'development of acoustic sensor for hearing impaired persons.'
Inventor(s) include Dr. Sunipa Roy; Ms. Palasri Dhar; Dr. Somdatta Paul; Dr. Ipsita Saha; Shubhadeep Bhattacharya; and Mrinmoy Dutta.
The application for the patent was published on April 17, under issue no. 16/2026.
According to the abstract released by the Intellectual Property India: "The present disclosure discloses a portable device for assisting hearing-impaired persons by capturing environmental sounds and instantaneously converting them into vibrotactile feedback. The device comprises an acoustic sensor, a digital sound processing unit, and one or more vibrotactile actuators. Advanced algorithms utilizing zero-crossing rate, Mel-frequency cepstral coefficients, spectral subband centroids, and line spectral frequencies are employed for robust sound classification. Distinct vibrational patterns corresponding to different sound categories are generated in real time, enabling users to perceive critical auditory events such as alarms, horns, and doorbells through tactile sensations. The system incorporates high-sensitivity graphene-based acoustic sensors, operates with a rechargeable portable power supply, and delivers response times of less than two seconds, thereby providing an efficient, reliable, and user-friendly assistive technology for hearing-impaired individuals."
