I'm looking to construct a transparent sound booth to conduct seated audio recorded interviews in public. It doesn't need to be completely soundproof, but it needs to significantly buffer sound from the street (it might not need a top) and it must be see-though so that pedestrians can watch interviews. I'd also like to be able to assemble/disassemble fairly quickly (20 minutes tops) as it won't be based in a permanent location. Any ideas or guidance? Thanks!
