Duty Finder Notifications Feature?

[JemC]

I was thinking about this today. I want to lift weights in my apartment and people coming in and out want to talk. I try to pay attention to the screen but get distracted. We can control the sound chat makes; can we control the sound this makes? Turn duty finder pop volume up or make it another loud sound? I can't hear it and I don't want to blast the game. Tho I try I'm not always looking at the screen when it pops.

I'm on PS3 but I'm down with Onyx suggestion as well. Option to make it flash?
