I have to block off a hallway that leads into my studio space and I'm looking for recommendations on what type of curtain to use for sound control. The opening in the photo is about 2 feet to the left of where my desk and monitors will be, which will be pointed away from the opening and in the direction of where I made the photo from.

Thanks for the feedback!

 

If you need a curtain you can use molton which is used in theatre.

You could also get some moving blankets which work really well
