I am remodeling a home, splitting a 4th bedroom in half to make a bigger master bedroom and bigger living room. For sound dampening purposes, I'll put in R-19 bats in between the studs of the new wall, then cut strips of cardboard boxes attached stud to stud, then sheetrock over the whole thing, tape, mud, sand, texture, and paint.
Anyone see why this could be a bad idea? It seems like the corregated boxes would add an extra layer of soundproofing, and the sheetrock would have a buffer from being attached directly to the studs further slowing down sound.

Will you be running electrical wires through there? That's the only thing I can think of that might make using the cardboard a problem - the fire hazard.
If the wires short and burn, that cardboard would be a good enough fuel to keep a fire burning long enough to ignite the batting and sheet rock.
If you're not running wires through there, though, the cardboard should be a good sound dampener.
