Thanks for the reply. Sadly, set3DLevel does not help me here, because I do want the volume to be lower when the sound is emitted at far distance. Setting this value to anything lower than 1.0 will make it hearable from far away distances.
Setting the height of the sound does kind of work to lower the weird effect you get when the sound is on top of you (where you only hear the sound from 1 ear), but when the sound goes further away from you, you of course still hear it in 1 ear.
So I don’t think either of these solutions will work for me.
