Sound proofing is provided by materials that either block sound from entering an area or absorb sound to contain it in an area. Sound is measured in decibels. When you get materials to block or absorb sound, you will see that they have an STC (standard transmission class) rating. An STC rating depicts how much sound decibels the sound proofing material will block or absorb. An example: a normal wall has an STC rating of 20 or 25. This means you can hear normal speech through the wall. If you want the normal speech to only be heard as a murmur, you will need a wall with an STC rating of at least 42.
Now that you understand the STC rating of sound proofing materials, you can learn what means of sound proofing are available to you. A rather inexpensive method of soundproofing is to use foam sound proofing materials. The foam can fit in almost any space and can be either 1/2 inch to 2 inches thick. The STC rating of the foam is between 40 and 50. Another mean is to use vinyl sound proofing materials. Vinyl materials have an STC rating of 42 to 55. For floors (such as in the case of multi leveled buildings) you can utilize sound blocking carpet underlays that fit in between the floor levels. Carpet underlays have an STC rating of 29 to 40. Inexpensive metal wall channels are also available. These attach directly in your walls and ceilings. The STC rating for these is 38 to 50.
These are the many different means that you can use to soundproof your environment. The prices can vary depending on how much sound you wish to block and how big of an area you wish to cover. With careful research, you should be well on your way to a more peaceful and quiet environment.
