Air Force Research Laboratory MultiTalker® Helps to Make Cockpit Safer 

What is the Science behind MultiTalker®

Several factors differentiate the PAC45L from the typical old audio system. MultiTalker® function in this digital audio system provides unprecedented intelligibility for multiple communication radios by applying the Head Related Transfer Function processing. Developed by the USAF Laboratory, this spatial audio uses the brain’s ability to differentiate conversations by placing them in different spaces relative to the listener. The PAC45L system can place three receivers into one of nine locations in the crew’s headset.  See the links above for more detailed information.

All audio wiring is made to the central HUB45AR, decreasing wire count and complexity. Serial data lines from the CTL45L control heads provide the control input.

The PAC45L includes Bluetooth® connectivity for telephone use as well as music or iPad audio alerts.

In addition, an independently powered Audio Alert system is present in the PAC45L. Up to 9 audio alerts are available, and through the use of IntelliStore™ each of these inputs can be custom recorded. Either rising, falling, or Sonalert inputs can activate these alerts based on available existing triggers. Once acknowledged, they are reset and then begin monitoring the inputs again.

CTL45L heads are available in Gray or Black. The bezel labeling is fully customizable at PS Engineering, providing precise labeling of the audio sources.
