a good idea, but if everyone can hear the sounds in the videos, why hasn't everyone heard the sounds outside? in order for your theory to work
everyone's ears would have had to change to detect the sounds, because everyone can hear the frequencies in the videos. yet, not everyone has heard
the sounds outside, so it makes more sense that no ones ears have changed. i think the best possible explanation is that the sound is really coming
from the sky/earth, or it is just a hoax
