You can’t live in peace if your walls are allowing sounds to pass through them. Every time you play loud music, your neighbours come to knock at your door. Or sometimes, it’s the neighbour who is making the noise.
However, this should never be the case. You can soundproof your walls and block most of the noises. Walls perform differently when it comes to soundproofing. Different walls allow different levels of noises to pass through them.
In this article, therefore, we will discuss 6 affordable ways to soundproofing a wall cheaply.
Factors Determining the Level of Noise Through Your Wall
The following are factors that determine the level of noises that would pass over the walls.
- The Type of Noise
There are two categories of noise that will force you to soundproof your floor. The idea is to block the sounds from leaving or entering your room in an apartment.
Below are the three significant noises that you should be concerned about when soundproofing your apartment floor.
- Airborne Sounds
These are the type of noises that travel through the air. Airborne noises from a crying baby, people talking, music system, T.V. Sounds, and any other sounds travelling through the air.
Airborne noises don’t easily travel through the walls unless they are thin or have cracks.
Airborne noises can be blocked from the walls by thickening it. Therefore, if you hear sounds through your wall, use thickening materials over it. In this article, we will discuss some of the thickening techniques to apply to the wall.
- Impact Noises
This is a type of noise caused by an impact between two items. Impact noises can easily pass through the wall. The noises are as a result of items hitting the wall.
Impact noise travels through solid surfaces. Therefore, when soundproofing your walls, you need to use different techniques to block impact noises.
- Structural/Vibration Noise
Structural noise comes from appliances. The vibrations travel through the walls, floors, and ceilings. The sound can move through any solid structure.
Some of the structural noises include Bass sound, humming refrigerators, dishwasher, washing machine sounds, and any other heavy sound.
For effectiveness, first, eliminate the noises from the sources — soundproof the appliances to reduce or dampen the vibrations. The best technique to do this is to use sound absorption materials.
- Wall Thickness
The thicker the wall, the better the effectiveness in soundproofing. Thick walls block airborne noises completely. Also, impact and vibration noises find it difficult to pass through the solid and thick walls.
Therefore, if you are constructing a house, make the walls as thick as you can.
- Material Used
Houses are built with different materials. These materials dictate the kind and level of noise that can pass through the wall.
The major construction materials are; wood, bricks, concrete, MDF, cardboard, and metallic sheets. Concrete and brick walls are effective in soundproofing. They can block high-frequency noise level like traffic noises. Also, they deaden impact and vibration noises passing through them. In addition, airborne noises bounce over the wall.
Cardboard and wooden walls allow all noises to pass through them. On the other hand, metallic walls amplify the sound bouncing off them.
Effective Ways to Soundproof Walls Cheaply
1. Seal the Ceiling Cracks
Wall cracks are a culprit in allowing noise to pass through them. The cracks differ by the material used over the walls.
Despite the material used to construct your wall, there are high chances it will crack. The wall cracks become an issue because they allow noise to pass through them.
Therefore, start by inspecting your walls. Check any cracks. Sometimes you might not see big cracks. It’s essential to be keen when inspecting your walls. Don’t overlook small cracks on your ceiling.
Even small cracks will need to be blocked. If not sealed, they will develop big cracks. Also, small gaps allow air and sound to pass through them.
For a proper inspection, rub the concrete wall surface. Clean all dust and check any cracks that you might have missed.
