Answer to:
Did the Big Bang make any noise? Yes there was noise as it still can be heard by machines today (as submitted by another person) but the noise occured straight after the Bang so technically there was no noise during the Bang.

Answer to:
If the universe is infinite is it possible that there is more then one "Big Bang" in existence and we just haven't been able to see past our local one yet? Yes this is possible in a way. The Big Bang created everything in existence so the only way there can be another "Bang"occuring now is if you count the currently expanding universe we're in now or another Big Bang in a different dimension as our own Big Bang would not have another happening in itself that would be weird.
