How to play one audio file at a time?

The piece that I'm working on is designed so that certain sounds are played depending on a sonic range finder input. My current problem is that I'm not sure how prevent overlaying and letting one sound file finish before starting another sound file begins. Does anyone have advice on how to go about this?
