Sound working with sensors (HELP)

Hi everyone, I have a question. I hope someone can help me. I am just working on my graduation project. The problem is I dont know how to make it real. I don't know anything about programing or these stuffs. According to my project I have objects that will tell stories. and this stories will change according to the placement of the objects with each other. So how can I create something like that. Which arduinos do I need. I know that I need a distance sensor but How can I make that the sounds works. Please help. Thank you

(I hope it is not a topic out of this forum. Sorry I dont know anything about these.)
