it isn't really just audio though. The pilot is staring at things while talking, and there are automated systems like TCAS that provide alarms and visual indications as well. And a lot of commercial airliners have HUDs.

If anything, the helicopter needed more avoidance technology from the sounds of it. And that has more to do with the lack of integration the military does with civilian systems.

This was a perfect example where audio fell short. The ATC couldn't know if the heli was referencing the same aircraft. Some sort of digital display + highlighting would fit here.
