Audio & Sound

Filed Patents 10 patents

Overview

This month's 10 filed audio and sound patents come from Sony (9) and Microsoft (1).

Sony's applications focus heavily on accessibility features for gamers with hearing loss, including multiple AI-powered systems that adapt game audio in real-time based on individual hearing profiles and audiograms. The company also filed several patents for wireless speaker systems that enable headset-free gaming through echo cancellation, beamforming, and multi-source audio mixing of game sound, music, and chat. Microsoft's filing covers acoustic modeling technology that simulates sound propagation through dynamic portals like doors and openings in games and VR environments.

Company Activity

Sony received 9 patents this month, with a strong emphasis on making gaming audio more accessible and flexible. Four of the applications address hearing loss through different technical approaches: one uses AI to adapt all game audio based on individual audiograms while preserving the original sound design's integrity, another applies frequency-specific gain that changes depending on whether a sound is quiet or loud, a third uses pre-stored filter combinations to efficiently boost specific frequencies during gameplay, and a fourth weighs audio modifications based on spatial position and sound type. The remaining 5 patents center on wireless speaker systems that let players game without headsets. One application describes speakers that can receive audio from 2 wireless sources simultaneously (like a console and phone) while using echo cancellation to isolate voice chat, another adds beamforming microphones to that setup for better voice pickup, and a third layers in multiple stages of equalization control. Sony also filed a patent for speakers that track a player's position in a room and adjust their output to maintain optimal stereo sound as the person moves, plus a system that lets users position non-game audio sources like music and chat in specific locations within a 3D soundscape to prevent them from interfering with gameplay.

Microsoft received 1 patent for acoustic simulation in virtual environments. The application extends precomputed wave-based sound propagation to handle doors, windows, and other openings that can open or close during gameplay, solving a limitation where such techniques previously only worked when every surface stayed fixed in place.
