Spatial Audio Holography
Sub-Degree Directional Acoustic Sound Fields
Synthesizing customized 3D sound fields so that distinct listeners sitting on the same couch hear completely different audio without headphones.
Technical Explanation
Current spatial audio requires users to wear headphones. Spatial Audio Holography uses large distributed speaker arrays controlled by 6G edge processors. By calculating acoustic wave interference patterns in real time based on listeners' exact 3D head positions tracked by 6G ISAC radar, the system beams sound specifically to individual ears. Person A on the sofa hears English audio while Person B hears Spanish, with zero headphone hardware and zero audio bleed.
Key Functions
- Generating personalized localized 3D sound zones without requiring headphones
- Acoustic beamforming focusing sound waves specifically onto individual listener ears
- Zero acoustic bleed allowing multiple people in the same room to hear separate audio feeds
- Real-time listener head tracking driven by 6G ISAC cellular radar positioning
- Transforming smart home entertainment, automobile cabins, and open office spaces
