What if humans made an oof sound when they died?

Warzones would become even louder with the combined sounds of frag explosions, gunshots, and oof sounds. What if there was a nuke and millions of people died at once? What if it was the same for animals? If a stone fell down and crushed an ant hill, you would hear the collective oOF from the ground below. Since flies have a very short lifespan, you would be hearing OOF sounds daily, not knowing where they were coming from. What if a person was silently murdered and they made an oof sound? Would anyone know if it was a person or an animal? Would they care? Homicides and assassinations would be a lot easier to solve. What if “Oof-Silencers” were sold on the black market?
