Loud. Noises and pregnancy

So in work in an area where military aircrafts above me pass by constantly. They sometimes make the building shake and can hear them inside (only sometimes). So as I was walking outside, a jet flew above me and it was tremendously loud to the point where i had to stop walking and cover my ears. Two cars started alarming from the piercing sounds. Will it harm the pregnancy? Currently 7 weeks... please share experiences too :)
