If you love subtle audio cues, Japanese train stations are going to blow your mind.
Someone made a 20-minute audio compilation of assistive cue recordings, and 3/4 of them are various bird sounds to signal the way out from a train platform.

Another one I know of is in the JR East area: the (perceived) gender of the speaker denotes whether a recorded announcement is for the even number platform or odd.
