The keynote at Auto Shanghai 2023 from Polestar’s CEO was delivered in both Mandarin and English in the same room without any wearables.
The speech was delivered via two dedicated listening zones, creating live simultaneous translations. This was achieved by using 3D Audio-Beamforming and Wave Field Synthesis.
Holoplot’s X1 Matrix Array allowed attendees to follow the live presentation in English or follow a simultaneous live translation in Mandarin Chinese.
The system configuration comprised a main X1 array positioned above the LED screen, covering the area closest to it. Two pairs of X1 suspended at the left and right corners were used to project sound towards the opposite audience zones. This involved configuring the stage as a rejection zone, ensuring the cabinets on the left side would reach the audience on the far right of the room while avoiding the middle area. The same principle was applied to the other two cabinets on the right side and allowed the presenters on stage to deliver their speeches in a much more natural way.
