Real World Application of Physics

In this small project, you are going to identify a “Real World” situation and analyze it using physics. The Real World situation, in this case, would be instrumental sound waves. All you have to do is,  fully describe the scenario, as well as why it matters, to you or to a broader group. Please include books, web pages, and other resources did you use to find the problem and determine why it is important. In words and in equations, how the physics we are learning (simple nothing too extreme)  impacts your scenario. Using multiple steps, explaining how you know what to do, each step of the way. You can use diagrams if need be.
