Are you frequently disturbed by different sounds entering your room while you are working or sleeping? It is then time for you to take a look into the different sound proofing techniques. Sound proofing is done by materials that either block the sound from entering the room or absorb the sound to contain it in an area. Since sound is measured in decibels, all the sound proofing materials have a standard transmission class rating. This helps to depict how much sound decibels the sound proofing material will block or absorb. A normal wall has an STC rating of 20 or 25 which allows you to hear normal speech through the wall. If you want the normal speech to be heard as a murmur, you will need a wall with an STC rating of at least 42.An inexpensive method of soundproofing is the use of foam sound proofing materia c-plex60 ls. The foam fits in any space and can be either 1/2 inch to 2 inches thick. The STC rating of the foam is between 40 and 50. Vinyl sound proofing materials, having an STC rating of 42 to 55, are also used. He Inexpensive metal wall channels with a STC rating of 38 to 50 are other alternatives. The location of the home, the nature of the noise problem, and of course the budget of the homeowner is a major factor in determining the techniques for soundproofing required. One of the most effective noise proofing techniques for new construction is to stagger the location of the doorways so that they are not directly opposite one another. This technique restricts the sound from traveling across hallways and reverberating around the house. Absorbent materials like carpets, curtains or furniture helps to absorb sound.
