Far- heard sound using Detonator

I am using Detonator to create explosions (obviously). I can't quite seem to figure out how to make the sounds louder. The problem is that I am using a plane, and the distances are quite large, but I can't hear them unless I'm flying very low. I've tried using "distance threshold", "min. sound", and "max. sound", but it's still so hard to year.

you could change the object that the audio source is attached to so that it is closer to your audio listener,maybe parent an empty game object to your trigger/detonator object that is closer to the players natural distance during countdown

You can change the parameters of the audio source: min distance, max distance, rolloff
