I consider that proof that you don't understand what "exponentially" means.
Hint: if each person got twice as loud when there were twice as many people in the room (so, overall 4 times as loud) that would be merely quadratic growth. For exponential growth, each person would have to get twice as loud for each additional person, and human vocal cords aren't up to the task.
