How to Ensure Best Soundproofing for Walls

When it comes to creating a peaceful home atmosphere for you and your family, it is very crucial to take certain steps in that direction as early as possible.

Soundproofing is a foolproof method taken towards ensuring that your home interiors are not disturbed by any unwanted external noise, most of which enters mainly through the walls. This is why after conducting an extensive research, we have dug out the products, which provide the best soundproofing for walls.

Read on to find out more about soundproof wall insulation and the best materials and products for it that is currently available in the market.

Whether you live in the city or the suburbs, a noisy neighborhood always too much to deal with. If you have just moved and are experiencing it for the first time, or if you are tired of tolerating excessive noise from outside which is hampering your daily activities, maybe it’s time for you to consider the next course of action with regards to your wall insulation.

Most of the time, the thin brick, concrete or wooden walls are just not enough to keep the outdoor noise at bay. In such cases, soundproof wall insulation using cheap soundproofing material can create a world of difference in noise reduction. These create protective layers and barriers which obstruct the sound from outside to creep into your home, thus keeping your house sound insulated at all times.

Let us now look at the different wall soundproofing methods employed by homeowners:

Recommended Methods of Wall Soundproofing

These methods are the most commonly used methods for effective soundproofing and insulation of walls. Moreover, if you are wondering how to soundproof a wall cheaply and effectively, you’ll be surprised to know that these methods are not only less expensive but are also more effective than traditional methods.

You can decide to try a hand at applying these methods for your own DIY soundproofing project. The other option is hiring any local services or reputed and trustworthy brands for installation and set-up.

Doing your own soundproofing doesn’t require immense construction skills or specialized tools. With the right kind of soundproofing materials and proper electrical know-how and research, you can easily take up your house’s soundproofing wall project.

Below we will cover the few of the commonly used methods and their in-depth procedures:

Adding Mass

One of the most effective methods of soundproofing noise from the walls is adding materials of higher density. This significantly reduces the sound from inside and also costs less than half of the cost of traditional methods.

One of the common and trusted products in this category is the QuickBarrier Soundproofing Material sheet. It’s heavy, flexible and non-porous surface traps the sound waves, dampening their vibrations and preventing them from passing through. With much better noise reduction capabilities than steel and other materials, QuickBarrier Soundproofing Material ensures that you get more than you pay for.

Adding Mass

These can be applied during construction by nailing them to the studs. Else, it’s easy “peel-and-stick” backing enables it to be easily attached to the existing drywall.

You can also first attach furring strips to the drywall before applying the product, after which both the layers are coated with a second layer of drywall. After installation, all remaining cracks and seams must be sealed by caulking or barrier tape. 

Recycled Cotton Batts

Cotton batts are beneficial for reducing noise by absorbing the sound inside the wall itself. These prevent the sound waves from bouncing back and forth between the different wall cavities. They also serve as an insulating layer, owing to their density and thickness.

Quick Batt Soundproofing Insulation is a perfectly designed product under this category, which is a nice alternative to those itchy fiberglass and spray foams. They also perform visibly better than thermal insulators.

Recycled Cotton Batts

Made of densely packed fibers, these products provide external and internal sound insulation, fitting perfectly between wood and metal studs. They don’t require heavy and complex tools for installation on external walls. These serve multiple purposes and can effectively block out all construction, airplane and traffic noises, reducing their strong vibrations through their tight, frictional fit.

Moreover, they also provide thermal insulation, owing to their dense, cotton fibers and high insulation quality.

Sound Insulation Systems

This is at present the most effective and efficient soundproofing method in the market today. Sound insulation systems can go so far as completely cancelling the noise from outside as well as from other rooms, resulting in the best soundproofing possible.

One of the most popular products in this category is the isoTRAX Soundproofing System which works specifically by “floating” a wall mounting over the studs. This blocks the passage of sound waves due to absence of any common studs, thus causing noise reduction.

Sound Insulation Systems

Fastened to the studs, it provides no direct contact between the hardware and the wood. The studs are padded by a peel and stick dampener while applying the metal tracks. Moreover, each track in the sound insulation system is layered with neoprene foam that cushions your drywall from external vibrations.

With a simple and hassle-free installation and set-up, it makes your walls more rigid and provides top-notch soundproofing quality.

Traditional, Less Effective Methods

Staggerred Stud Walls

Usually when a wall is constructed, the studs connect the two sides of the drywall. This connection enables easy transmission of sound waves, and hence allows noise to enter the house.

In a staggered wall construction, studs are meticulously and cautiously connected to one side of the wall and not on the other. This, in turn, helps in reducing noise transfer significantly.

Staggerred Stud Walls

Although it requires cheap soundproofing material, yet the construction procedures are expensive and take up quite a lot of space. Moreover, this method plays a role in reducing the very structural integrity of the wall itself.

Double Walls

This method is traditionally used for an effective soundproofing set-up in construction of music rooms and studios within your house. Their room within a room system in the form of double wall construction offers complete noise cancellation by using standard soundproofing materials.

There are a few drawbacks to this method-- including high costs, complicated installation procedure and requirement of extra space.

Resilient Channel System

One of the most effective sound reducing materials, resilient channels acts as a spring between the drywall and the studs. It’s a spring metal track, which separates the drywall panel from other wall constructions.

On striking a wall equipped with resilient channel, the sound waves make the drywall vibrate independently. This vibration is not transferred to the studs due to the presence of the resilient channel, thus blocking sound transfer.

Resilient Channel System

This method requires a complex and systemic installation, and hence is not that common now. Also, it loses its utility when the structure of the building shifts or nails are driven into the studs for hanging some items.

Final Thoughts

All these above methods were used traditionally for soundproofing, but with advanced technology and new, scientific innovations and better quality of materials, soundproofing walls have become a highly efficient, simple and cost-effective task. With numerous revolutionary sound insulation products available on the market and online, sound proofing the walls of your house for ensuring a quiet and relaxing atmosphere has never been easier.
