alright...you guys have never failed me before with your acoustical abilities. So here is what I am dealing with. my project studio is in my basement. The isolation room - is all concrete but there are a few spots where pipes come through the concrete and there are spaces that allow sound to travel from the laundry room in to the iso room. What is the best way for me to seal these piped areas. I have thought about using insulation or blankets - i just want to make sure I am safe. Safe and cheap are what i am aiming for. The cracks aren't too big so whatever I choose to use to seal the openings shouldn't be too big. i'll try to get some photos to help you get the picture on this one. so the question is..what do you use/what should I use? I just started building the isolation room in the last couple days. here is what i've got so far.

like i said - all concrete walls. we have 4x6 carpeted cubicle panels hanging about 4 inches off the walls. we have 2 panels for each wall - we'll be hanging sound proofing blankets between the concrete and the cubicle panels. we also put down shag carpet. the rooms dimensions are 10x7.5x7 -

i would like answers as quickly as possible because we need to be tracking as soon as next week. thanks for the help
