audio emitter help

I am curious about the audio emitters I am placing in my game. I see the parameters and I am trying to adjust them so that the sound is heard far off. The problem is that no matter what I do nothing changes the reference distance of the sound(inner or outer).Basically I have this house that is on fire and I have had to place about 13 of these things around the house just to make it sound good at all positions around the house on the ground level. Is this normal or am I possibly using it incorrectly? I am using Torque 3D Game Engine 1.52.Here is one of the scripts for the emitter...thanks for any help offered.
