A macroeconomics teacher makes an announcement about the curve.

For my sound analysis, I recorded the first ten minutes of my macro with the certification of my teacher. In the moment, I was distracted from my recording because the teacher announced the curve that was going to be implemented.

My mic was farther from my paper than I was, but in the recording it was easier to hear my pen moving across the paper than it was when I was taking notes in class! After recording, I reviewed the sound and found that the teacher was surprisingly very easy to understand, and that the reactions of people around me were remarkably easy to hear, though I did not even hear them during the lecture.

There is a clear distinction between the background and foreground sound in your recording.
It is very interesting that you did not hear the sound of paper and pen since you were paying attention to class at that time, and the sound of the paper and pen became very obvious. The raw sound we heard is very subjective, we chose to pay more attention to certain sound than the other. Like in this case, if you listen to the recording, the sound of papers and other noises are sometimes a lot louder than the teacher's voice, but when you were recording, you ignored other sounds and focused on the teacher's voice.
