There's that really distinctive "Asian cicada" sound. Sustained, repetitive "wiu wiu wiu" and then suddenly a shift to slightly lower, flatter tone that is held for four or five beats "waaaaaa." My musicologist friends could describe it better, I'm sure, if they heard it.
I don't recall hearing that particular, very distinctive cicada sound anywhere in the US (that doesn't mean I've never heard it… just that it never seemed salient). But I remember it from summer in Korea in 91, and from my summers here more recently. The one other place I've heard it and really noticed it, is in Japanese anime — it seems to function like an audio signifier for "hot, humid, summer stillness," kind of the way traditional crickets chirping signifies "silence" in American cartoons.
I really like the sound.
