Does anyone know a good way to exaggerate the sound attenuation? I am trying to make it extremely obvious (if you are paying attention) while playing my game that there is a hidden obstacle right in front of the character. Currently, I have the attenuation set to 1 (Default) and a max distance of 30 (which is about 4 tiles wide in my game). So on the far side, the player just faintly hears a noise, and when you are right next to the obstacle you hear it more clearly.
What I would like to have happen is on the far side the player barely hears anything, with much more clear volume increase points (for lack of better wording) up until the player is right next to the obstacle. I think the current setup leaves to much guesswork, "Am I one tile or two tiles away?"
Thank you.
