The sound was only audible up to 3000 miles in radius, or about 1/13th the globe. It wasn't audible in the other side of the Earth (although it was detectable.)

The fact that sound was only audible up to 3000 miles in radius is not enough to rule it out, you need other arguments.

("It is thought by some to have been created as seismic waves from the impact converged on the opposite side of the planet.")
