Take any overflow box - internal or external, doesn't matter - and drill two holes in the bottom (holes will be in the bottom of the tank for an internal box). Put an ordinary standpipe in one hole. Leave the other hole as is. Put a gate valve under the no standpipe hole and adjust it so the water level in the overflow box is just seeping down the standpipe. Voila . . . dead silent overflow a.k.a. a Herbie.
