Reflection on my sound paper topic

I changed my topic from How the Nazis manipulated sound to The evolution of Sonic Weapons, but after thinking about it, id prefers to create the first one. Unfortunately, there is barely any information about sonic weapons in between the nazis Schallkanone to the modern-day LRAD, making it extremely hard to fill the gap with something interesting. Furthermore, How the Nazis manipulated sound is an interesting topic with lots of information out there, along with having more audible sounds to play in the audio paper.
