I'm am a guitarist looking for a way to play minus noise escaping, is in that a way to do it for cheap?

Please be specific.
Glass doors that alter from clear to frosted...
Yes, I would like to know that, too, but I guess you can't find any cheap ways to do it. I know that here we are planning to "carpet" our company room so that the sound would be softer and all right, maybe it will also give a hand a bit in that situation, but yeah hehe, if I take it realistically consequently ...
Help Please!! How to cover a doorway...

I entail some suggestions for updating my home?
The cheapest way is daily egg cartons. They dispurse the nouns over more surface area, so more nouns absorbs, and smaller quantity escapes. you have to cover every inch of the room, though: walls, floor, ceiling, window and doors, too. You can paint them all funky and fun.

Another solution around doors and window is foam rubber.
Most of the cheap recording/rehearsal studios I go to use the egg carton and foam rubber combo.

Answers:    They be paid 1/2" sound board available at Sheetrock supply houses. You can do it several ways: Best solution: attach 1 1/2" furring on the walls and ceiling, put contained by 1 1/2 sound batts, cover it beside the sound board, mat the floor, replace the door with a solid core door, and apply a jute face wallcovering. It will cost you about $1 a sq.ft. of wall space, if you do the work yourself. It will not be soundproof, but it will be terrifically close.

They make nouns panels, but they are expensive in the region of $15 a sq.ft.
