What is that sound? (Destiny)

I've noticed some weird location-based sounds while running the VoG, right before we pick up the relic to fight the Templar. It sounds like two rock faces scraping together.

My running theory is that, because the location of the sounds seem inconsistent between runs, it's a bugged sound-effect that keeps looping that plays after a Vex dies.
