Very loud whirring pulsing noise from a POI

In the Abeyance/Forest realm, I came across a floating block location with a POI on the side of it, that had a button attached to the wall above a gate where there is a chest inside. There is a divider wall where there is a button triangle on the floor to release the essence once the POI is completed.

Once the POI was completed, thre is this very very loud whirring pulsing sound coming from the POI. So much so, you can stand back from the gate location about 5 feet to hear it, then move back about 100 feet, still being in front of it, and STILL here it. I have tried turning down "SFX Volume" and it does not change this.
