Actually, this is what the book "Who Is Fourier?: A Mathematical Adventure" is about. It's the adventure of a group of families who wanted to learn more about languages, which led them to sounds which led them to learn about Fourier transforms. It's a lot of fun and it actually has real math that you often get to learn in a signal processing class in college. While it is very focused, this book and the approach will pique your interest in other topics.
