Several layers of thick blankets should help actually. Ensure they cover the entire opening, allowing you to push them aside for ingress/egress. The air gaps and rough patterns in the blankets will assist in deadening any sound passing through them.

The barrier is a pretty bit project, but it might give you some ideas.
