We're already being loud. We've been leaking radio transmissions into space for the past century.
We have barely uttered a sound in the universe.

Although there could be aliens on another spiral arm, or Andromeda, communication would take longer than the lifetime of our civilization; and material trade would take longer than the lifetime of our species.
