What is sound proofing?

Soundproofing is a method by which you reduce the amount of sound or noise that either enters or leaves a room. Otherwise known as noise or sound control, there are several different methods for soundproofing depending on the type of noise you are soundproofing against and the source from which the noise originates.

There are to main methods for soundproofing - sound absorption and sound blocking. Sound absorption is used in situations where you may want to absorb sound before it leaves the room you're in. An example is in a Home Theater where you may use high volumes but don't want the sound to disturb those in other areas of the house.

Sound blocking is a method in which you keep sound from entering a room. An example would be soundproofing your bedroom so that you do not hear noises from your kitchen or laundry room as you try to sleep.

In some cases, like in the creation of a sound studio for music recording, you might want to use soundproofing materials that can perform both functions. That way your music isn't marred by outside sounds and you aren't bothering those around you either.
