The only way to block sound effectively is with mass--doesn't really matter what (mass-loaded vinyl, lead sheet, heavy foam) as long as it is massive. I build organs in my day job, and we use 3/4" MDF sealed with polyclear to make swell boxes (enclosed spaces with shutters on the front that can be opened or closed to control volume); the panels are very heavy, but have to be to be effective.
