Bowling Balls in dungeons
There are specific sounds like this in various places in the game. A specific ambient sound seems to be non-ambient and plays at full volume. This also happens with some end-of-event speeches to me. I can be miles from the end of a local dynamic event, the usually bronze medal pops up, and the follow-up dialogue plays like I am standing inside the mouths of the NPCs talking.
I would think making specific reports of what sound and where will get them fixed. Some have been corrected as stated in the patch notes, so they are fixing them when they know about them.
