It will create a very weird auditory illusion. It has a similar rhythmic pattern of ocean waves with highs and lows. The sounds will also come in waves as a point in the "song" will ripple across a vast distance sometimes when they are out of sync a bit. Think of 1 million people playing 2 million maracas at the same time and you might get an idea of what it is like during one of the big emergences.
During the first part of the emergence, at night you'll hear the strangest noises coming from the ground as millions of them start digging their way out of the ground. It can be really freaky if you're outside on a quite night listening to that happen. You also get to hear them split open their skins, in the millions.
The up side to all of this is that you can eat them, everything else can eat them, and there's great fishing during that time if you use lures that look like them or hook them on. The worst part is that the young, sapling, fruit tress will get destroyed. The older ones just get a pruning usually.
