How to Deaden Sound Through Walls


Hearing loss is only one of the many health issues that may be brought on by prolonged or excessive exposure to noise. Noise that never stops may make it difficult to go to sleep and may also contribute to cardiovascular health problems. You are able to make adjustments to lessen the noise and soundproof the rooms that are most impacted by the noise in your home, even if it sounds like Grand Central Station during rush hour. Even if you live in a condo and share a wall with a neighbour, there are noise reduction alternatives accessible to you that may help deaden the sound that travels through walls. These choices can be helpful in reducing the amount of sound that is transmitted.

How Sound Travels

Sound is made up of waves with a low frequency, and these waves travel in all directions from the source until they come into contact with another surface. This surface may take in the sound and muffle it, bounce it around and cause it to resonate, or even transport it to the next room. In general, newly built houses are better at transmitting sound than older homes are because newer homes have tighter building membranes, which results in higher vibrations. Similar to how water may seep into rooms via gaps and crevices, sound can do the same thing. Sound-controlling products may either absorb sound or confine it, or they can do both.

Build a Barrier

According to Soundproofing Company, the number of decibels of sound reduction that a product offers may be determined by looking at its Sound Transmission Class rating. A typical wall without insulation has an STC rating of 33, which is considered to be a bad rating due to the fact that it allows loud conversation from rooms next to it to be clearly heard and understood through the wall. The sound transmission coefficient (STC) may be raised to 44 points by installing insulation and a second layer of drywall on top of the existing wall.

At this point, a person is unable to hear loud conversation, and music sounds muffled through the wall due to the proximity of the wall. According to Trademark Soundproofing, improving the soundproofing of a space may be accomplished by placing materials between two layers of drywall. Soundproofing materials such as sound-absorbing boards, mass-loaded vinyl (a rollable, flexible material), and caulk between the walls are all effective in reducing sound transmission. A STC value of 60 or above is indicative of the superiority of certain soundproofing materials.

Put a Lid on It

According to Houselogic, acoustic panels not only increase the sound quality in home theatres but also minimise the amount of sound that travels across rooms. Made of porous expandable polypropylene, they absorb sound before it ricochet off walls and ceilings. The panels may be fastened to the walls using clips or hook-and-loop tape, and they are available in a number of different sizes.

Some firms provide artwork, a selection of different fabrics, or even the option to have materials made specifically for your design. You may limit the amount of sound that is transmitted through and reflected off of a wall by as much as 30 percent by painting it with sound-reducing latex paint. The soundproofing of the paint is achieved with the use of sound-absorbing fillers and resins, as well as hollow ceramic microspheres. However, the colouring options for the paint are limited to a palette of light pastels.

The Soft Touch

A room that is filled with hard surfaces causes sound to ricochet and bounce all across the area. It is possible to diminish sound wave vibrations and reduce noise by adding soft furnishings such as rugs, carpets, drapes, upholstered furniture, and even potted plants. This helps to create a more comfortable environment. When you purchase a carpet the next time, be sure to look for the STC rating, since almost all carpets will have one. This will allow you to choose a carpet with a higher score. In addition, you have the option of installing a white noise machine or a waterfall with trickling sounds in your area. These things produce unstructured noise that is added to a space, which effectively covers out other noises.
