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

Try the yellow spraycan foam that you can buy from any hardware store. It comes with a nozzle and will fill the crack 100%. It makes a great weather and sound insulator. The stuff is usally on the isle with the doors and windows, because it is such a great sealer for that type of work as well.
Best of luck

Our A/C ducts go though the wall between one studio and the other. When we installed them we wrapped the ducts with a type of foam rubber that is used for just such a purpose. Then we carefully calked around the hole and then had our carpenter put wooden cutout templates on both sides of the wall and calked them as well. We have no sound transmission through theduct or the walls around them. Not too expensive and worth the trouble. Not sure how much "sound" will be stopped with foam in place foam. I think you are going to need something with mass and dampening.
