That's the point though; it wasn't an explosion. An explosion has to explode outwards into something (space). The Big Bang was the expansion of space. There was no space before the Big Bang! Everything was contained within a singularity (infinitely small, infinitely dense) which expanded into everything we see today.
The Big Bang itself didn't have any sound, since there wasn't any space for the sound to travel in. The aftermath of the Big Bang (when the space had expanded and continued to expand) would have been exceptionally noisy, but not before, nor at the point at which the "Big Bang" occurred.
I wish people would stop this nonsense about it being an explosion. As I said before...just a name.

Quote:The Big Bang is not an explosion of matter moving outward to fill an empty universe. Instead, space itself expands with time everywhere and increases the physical distance between two comoving points.
