Decouple the Walls. Decoupling is one of the most effective forms of soundproofing. You cannot afford to skip decoupling if you want to achieve a high degree of soundproofing.
Add insulation in the Walls. Insulation is another element of soundproofing that must be looked into. Insulation helps in avoiding resonance in air cavities and hence,helps in soundproofing.
Install Double Drywall and Green Glue. Another two important elements of soundproofing are mass and damping. If budget constraints do not allow both,damping can be excluded.
Decouple the Ceiling. Just like the walls,you will need to decouple the ceiling for soundproofing to be effective.
Insulate the Windows. Double glazing and window plug are the two best options for soundproofing a window.
Seal the Gaps Around the Windows. If there are gaps or cracks around the windows,sound will leak inside even if you have double glazed windows installed.
Install a Solid Core Door. Standard hollow core doors are absolutely ineffective for blocking out sound because of low mass.
Seal the Gaps Around the Door. Like windows,sealing the gaps and cracks around the door is a step that cannot be missed.
Apply heavy Padding or Carpet on the Floor. The floors should not be ignored especially if you have a concrete floor.
Soundproof the Air vents. Air vents are a major source of airborne noise leaks.
How does sound travel through walls?
All surfaces absorb sound to some degree, and sound waves go through solid objects just like they do through open air, although solid surfaces absorb more of the sound. Unless they have significant insulation or consist of solid rock or masonry, most walls allow sound through to the other side.
What is noise reduction?
Sound or noise reduction is a process of applying engineered solutions to noisy equipment or processes with the main goal of mitigating the sound levels.
