Hello,
I don't know what sounds fall in this category. But e.g. there is a sound that I would call "latin male clerical choral" when you be near this little helo echos near structures. Spyclass show me 25 meters distance if background music is off, with background music 15 meters, before I can't hear this sound any longer. In opposite, if I bounds spawn at night I can hear this sound from more than 150 meters.
