When solving a noise problem, you need to establish a few things:
1) Is the noise coming from within this space or is it coming from an adjacent space?
2) How loud is the noise in dba (decibels) Radio Shack sells sound level meters for about $ 60, not very good but he got the ballpark.
3) How strong would you like. Off cource dead Silence is not a reasonable goal. Note that most households and offices are located on or about 35 to 45 dba, for starters.
Here are for some answers: Products that increase the TL of a divider are rated with an STC (sound transmission class). You need to increase the transmission loss (TL) of the materials that make up the partitions between the rooms (i.e., drywall, plaster, doors, windows). If your noise source were in another room and you'd like to keep it there.
The number of NRC is something completely different and is part of the most commonly misunderstood acoustics. The number of NRC is something completely different is one of the most commonly misunderstood acoustics. Foams also tend to be a misrepresentation. In order to enhance the TL of a partition, you must increase its mass. That's not to say they have no place in acoustics. They simply do not work for this problem. Be very careful when searching for "Acoustic" products that do not give an STC rating if you want them to increase their TL. They simply do not work for this problem. Look for products that have an STC rating of STC 26 or higher. Closed cell foam and spraying the material does not. Some of these may be a vinyl barrier burden 1 or 2 pounds per square foot.
