why does this happens? (sound related)

[caleman]

so i import sounds to my map and give them to spells (at the positing of the casting unit or where the spell explodes)

the thing is that they can be heard everywhere, for example im at the north of the map and if a unit casts the spell at the south, im able to hear it

anything you know about this is welcome

Make sure the sound are 3D sounds and all the settings are ok.
