Noisy rooms are very common today. For instance, sound from a TV or fun-filled conversations among friends engulfs the living room. The sound of mixy spreads across the kitchen. Sound from the music system rocks the bedroom.
If these sounds from various sources are not controlled, they will disturb the atmosphere of other rooms in the building. After all, a person trying to fall asleep in the bedroom doesn’t want to be bothered by the loud TV sound, and the people watching TV don’t want to reduce the volume and strain their ears.
This is where soundproofing or sound insulation helps. Soundproofing is a technique of controlling the sound waves inside a room and confining the sound well within the room’s walls.
The process of soundproofing a room involves using many materials that insulate sound waves.
Soundproof doors, soundproofing foam, soundproofing panels and various sound insulation materials help in soundproofing a room.
1. Soundproof doors and windows:
Sound penetrates through doors and windows easily. Hollow wooden core in doors adds to the issue. Install solid wood doors to block sound from leaking.
Sound Transmission Class (STC) rating indicates the level of soundproofing material that can provide. A hollow core door ideally has an STC rating of 20 or less. A good soundproofing weather-stripped solid door has an STC rating between 34 and 36.
In the case of UPVC doors, you could use soundproofing glass panels to create soundproof doors. The glass used for doors is either toughened glass or laminated glass. Adding another layer of soundproofing panel helps stop sound leakage and provides a thick layer that is difficult to breakthrough.
2. Soundproof walls and ceiling:
The greater the wall’s density, the better the soundproofing capability. You can use additional layers of Gypsum sheet to increase the wall’s density and increase sound insulation.
You can also fill the walls with fibreglass/Polywool insulation and fix resilient channels and a sheet of Gypsum to improve the sound insulation of the walls and ceiling. A resilient channel is a thin metal channel that acts as a shock absorber.
The addition of a resilient channel to the existing wall can increase the STC rating by 3 to 5 points. You can easily install a half-inch thick resilient channel to achieve dramatic sound insulation.
3. Airtight the room:
Even a slight crack or hole could let sound pass through a room. Electric boxes and switchboards often create gaps and cracks in the wall through which sound escapes. You can use silicone caulk to seal the gap between the boxes/boards and the Gypsum.
You can also use weather-strip gasket tapes to cover the unwanted cracks. This approach of soundproofing is hassle-free, inexpensive, effective, and doesn’t consume much time.
