Does anyone have experience with the use of strip-doors (hanging plastic strips) for reducing 
sound bleed on the floor?  We're using them to help create quiet spaces for individual exhibits.
I'd love to know anything about people's experience with them, but in particular: 

• What are your criteria for when to use them, as opposed to a hinged door? 
• Have you always used full-length ones, or shorter (which seem to work nearly as well 
acoustically)?
• Do you know whether they tend to discourage visitors from entering the space, or whether 
vistiors feel weird, as if they're in a meat locker, etc?

Thanks for any responses to the list or offline.
