There exist several reasons for carrying out soundproofing. The most important reason among them for soundproofing being creation of a peaceful environment. You may be troubled by the traffic noise outdoors or the noisy neighbors in the flat above or adjacent door in a multi-residential building or office building. You may also wish to carry out the soundproofing of a juvenile’s bedroom for keeping away the clamor of the stereo, or the baby’s room for keeping noises out. Whatever may be your reason for desiring a quieter and lesser noise; there exists a definite soundproofing method for doing the particular job right.
In case you have taken the decision to take up the soundproof job yourself, first you have to determine where the source of the noise is. This will help you to plan how to approach the issue of soundproofing. Sound can originate from a very large number of sources both internal as well as external and therefore you have to start by switching off every one of the appliances and other electrical items at home and listening to track the source of the sound. You are aware that noise can pass through even the tiniest of gaps or cracks in your room and so you will start checking the windows, walls, doors, ceilings and the corresponding sealants.

Soundproofing can give more Privacy:
The uniqueness of soundproofing of an area like a wall is judged by sound transmission class (STC). Normal private conversation can be heard and comprehended on the other side of a wall of STC-25 rating. When you improve the soundproofing to STC-60, not a difficult one to achieve, a loud shouting will be audible but not comprehended. For a good outdoor wall only adding thermal insulation like cellulose or fiberglass, will save energy, but that alone will only marginally help in soundproofing it. If you make the wall totally airtight it might have a larger impact in stopping external noise from neighbors and traffic.
Inner walls in most of the homes are not thoroughly insulated. A single drywall layer nailed to 2×4 studs will have a STC of about 34. This would mean that loud talking can be heard and understood on the other side of the wall. In older homes, there can be openings and gaps in walls making things much worse. A minimum of STC 48 is specified for a normal bedroom wall when the adjoining bedroom is normally not noisy. In the case of a bedroom wall adjoining a noisy living room or a kitchen, the minimum recommended is STC-52, STC-58 being considered optimal. The level of noise tolerance also varies according to individuals.
