Rehabilitation centers.
A room similar to the lobby,tower,hangar etc. where they woudl have to spend the remaining time of their muting and be forced to listen to music like
Somewhere Over the Rainbow" - Judy Garland
"Body and soul" - Glenn Miller
"Buy buy buy Bonds - Bing Crosby
"Why Do They Call a Private a Private" - Ethel Merman
Over and over again
A few rounds of that should be enough to cure anyone
