Quest Items making spawning sound from far away.

I am currently in Jiquani's Machinarium on the character "Darling_Jerome". When I entered the dungeon and went west I started hearing the Important Item Drop sound from my loot filter. Eventually I discovered it happened when passing a certain threshold. I'm guessing that one of the Soul Cores was being spawned and despawned based on distance. This wound up being pretty distracting, as the sound it makes is the same as a valuable orb.
