Interesting, but kinda hard to believe that the sounds we hear in the forest could be coming from that high up I'm no expert, but if that's true, that's pretty mind-blowing

One thing that I found super interesting when I studied audio engineering is that our ears are very good at determining direction left/right, but absolutely hopeless at working out if a sound is up or down.

This makes their hypothesis a lot more believable to me; I can understand others incredulity.

> absolutely hopeless at working out if a sound is up or down

Easy, just turn your head to the side :P

The article explains that this objection was raised by other researchers, but that the sounds were triangulated to a height of about 250 feet (because they are caused by an electrical interaction at the top of an inversion rather than from the aurorae directly).
