Proposed research question
What actually sound is? How can speakers reproduce it?

Why do I choose this topic?
Sound has always been an important part of our lives. From daily communicating to music, we are exposed to sound everyday. However, although it is always there, not many people understand the nature of sound.
​
What create sound? How can we hear it? These are some of the questions that lead me to this sound research, as a way to find out what actually sound is, and the way speakers reproduce it.
​
We will go through a concept of sound explanation to answer these questions!
