AuSIM 3DVx Voice Comm Series
Distributed Voice Comm Localization
for Stationed, Mounted, and Dismounted Teams
3D audio offers an opportunity to closely link members of a functional team
into a more effective, more cohesive unit.
AuSIM's 3DVx™™ system is an evolving platform to provide
high-precision 3D audio to active workers and equipment operators in a great variety or pursuits.
Based on AuSIM's AuSIM3D® technology,
3DVx provides the wearer with multiple discrete voices in
full duplex along with advanced aural information display capability.
3DVx™ combines a digital audio processing unit and professional-grade analog-digital interface with a network and a tracked headset to present the wearer with voices and audio icons which maintain 3D spatial relationships, regardless of the location or orientation of the listener. In addition to providing listeners with inherent location information of sounds and voices, the positioning of sounds in a 3D space enhances listeners' situational awareness, and enables them to perceive multiple sources concurrently, helping them direct their attention to any presented audio stream.
3DVx is an evolving platform to provide 3D (positional) audio to active workers and equipment operators in a great variety of pursuits. Based on AuSIM's AuSIM3D™ technology, the 3DVx, short for “3D Vox” (vox is Latin for voice), provides the wearer with multiple voices in full duplex along with advanced aural information display capability.
This is a flexible, expandable technology, starting with POC (Proof-of-Concept) systems and expanding to rugged wearable systems and digital, tracked headsets. The equipment can be built to any required degree of ruggedness, for commercial or military applications.
3DVx combines a digital audio processing unit and professional grade analog-digital interface with a network and a tracked headset to present the wearer with voices and audio icons which maintain 3D spatial relationships regardless of the location or orientation of the listener. In addition to providing listeners with spatial situational awareness through the inherent locations of sounds and voices, the positional separation enhances the ability to discern between multiple sound sources competing for attention.
Combining sophisticated algorithms and efficient signal processing with significant computing power, numerous discrete sound sources can be projected in in space around a headphone-wearing listener. 3DVx combines this capability with voice communications channels and position/orientation sensing devices (GPS, gyroscopes, etc.). The resulting system allows a user to maintain contact with other team members while hearing their voices propagated from the direction they are physically located. Additional information can also be conveyed in the listener’s aural world as “auditory icons”.
3DVx prototype system, now undergoing field trials
Using a local network, units share position, orientation, voice, and synchronization.
The network may be wireless, as complex as a digital radio Three Dimensional
Voice System for Team Communications and Dispatch Operators system capable of
carrying 300 Kb TCP/IP, or as simple as a standard hardwired office ethernet
environment. However, the portable nature of 3DVx makes a wireless connection
a necessity in most applications.
