I have a rather high end gaming rig, and this is the only game ive had this issue with. On top of that, this “sound wave” only occurs in WvW, and only in battles. The best I can tell is that it occurs from to many high quality sounds comming in at once and…. overloading the game. Im no technician but that seems to be the case for me. This wouldnt be so terribly bothersome if i didnt get dropped from WvW and forced to reque and not be able to get back in WvW for (most times) several hours. I hope you fix two things from this thread – the sound wave bug and stop kicking players that go offline / disconnect for about 5 minutes (is fair, i think). rather ridiculous to boot people just for disconnecting /game crashing right away.
