We live in the era of pollution. Noise pollution is common everywhere so after the long day we all want to go to our home and relax in solitary. But today’s houses are built in such a way that we can’t enjoy ourselves in quiet and find a little peace, thanks to the thin walls, lightweight construction and the high-tech audio and video gears. Any modern day home is filled with many whiz-bang kitchen appliances and home theaters. With all these, we are creating noise as a byproduct of our busy lives. There are many initiatives you can take to reduce the noise problem in your room.In this article, we’ll discuss the methods of soundproofing a room.
How sound works:
The physical action sends sound waves through the air which in turn reaches in our ear to vibrate the eardrum (the sensitive membrane present in our ear. We hear the vibration as sound.
Know about the sound reducing materials:
The conventional walls are built up of drywalls which in turn works like a drum. A normal wall has two normal membranous drywalls on the two sides of the structural framework which is indeed filled with air. The sound waves work by hitting one membrane on one surface and the air in between carry the waves to the other surface which makes it audible. To reduce sound waves, you have to include a resilient channel between drywall and studs. With the resilient channel, the outer membranous drywall vibrates separately and the vibration doesn’t get transferred to the studs.

You can use-
1. Fiberglass insulation batts or even old R-11 thermal insulation as a resilient channel.
2. The fire resistant type X 5/8-in drywall, which is denser than the other drywalls, so it prevents sound better than other drywalls.
3. Use acoustical sealants or silicone caulk in the drywall.
4. Use 1-1/4 in screws for attaching drywall to the studs and use 1 in screw for attaching it to the channel.
The procedure of making the room soundproof without demolishing the wall:
1. Insert the insulation to the cavity:
You have to cut a hole at the top stud cavity and blow the insulation in the cavity. Then you have to attach the new drywall sheets using the acoustical sealants and screws. Afterward, use the caulker to seal the hole.
2. If you don’t have a resilient channel, use whisper clips and headrails with screws. Using the whisper clips in a staggered way to the studs would do the trick. You have to attach the 5/8 inch drywall to the headrails. This will leave a ¼ inch gap both at the top and the button. You can add a second layer of drywall to secure the soundproofing.
3. Attach drywalls:

Screw the vertically placed drywall sheet to the channel’s flange. While doing the ceiling, place the new drywall horizontally to the channel. Always use 1-1/4 in fine drywall screws.
4. Seal the gaps:
Fill all the gaps between the floor/ ceiling and drywall using acoustical sealants or caulk. Don’t forget to seal the corner gaps.
5. Install sound blocking door:
Doors are the largest opening of any room. The interior doors which are used commonly are hollow inside, which makes these doorways almost ineffective of blocking sound. In this case, the solid wood doors work wonders.
6. Install transition strips and door sweeps:
Door sweeps and transition strip help to seal the gap under the door. A wood transition strip is a better choice because it is thicker than metal strips. The transition strip is used for covering the flooring joints. Try to use an automatic door sweep.
The main work of your sound proofing is to check the cracks and caulk. Seal all the holes up. While attaching the channel, remove the existing drywall. You don’t have to attach the resilient channel at both sides of the wall. Attaching it on one side is also satisfyingly effective.
