Here's a way to make it even quieter. I've used Durso standpipes since 2002, which are simple and quiet. They press together, no glue necessary. I noticed it was a tad echo-y under the solid lid, so I made a minor mod to tweak it and it made absolutely silent. This is in a 60g aquarium with a single 1" drain.
