Soundproofing Your Home (An In-depth Analysis)

In this blog post, we will talk about “soundproofing your home”, what soundproofing is, the materials used in soundproofing homes, the science behind soundproofing, why soundproofing is important, and how to soundproof your home. 

Soundproofing Your Home

Soundproofing your home can be made easy if you know the right ways. Here are a few effective ways to soundproof your home;

  • Seal Cracks and Crevices
  • Use Sound-absorbing Paint
  • Add Foam Tiles
  • Apply Mass Loaded Vinyl Layer
  • Use a Door Sweep
  • Add Door Panels
  • Insulate Floor, Walls, and Ceiling

What is Soundproofing?

The process of suppressing, diffusing, reflecting, or absorbing sound waves either at the destination or the source is called soundproofing. 

Various acoustic treatments are used to achieve this desired insulation such as using double-glazed windows, adding double dry walls, or using white noise machines & similar products. 

In simple words, the process of reducing unwanted noises from the home to make the living environment peaceful, calm, and serene is referred to as soundproofing.  

The process of reducing the noise produced by any means is known as soundproofing. We can also say that the removal of  unwanted voices or sounds 

What Materials are used in Soundproofing Your Home?

Many conventional materials such as recycled rubber and innovative products such as fiberglass are used to soundproof the homes. 

The material used depends on the type of insulation required and the state of insulation. Many construction techniques such as the use of composite materials during designing framing systems are incorporated to build soundproof homes.

While other products such as rugs, carpets, curtains, solid core doors, and acoustic panels are used to soundproof pre-existing rooms. 

How Soundproofing Works?

To understand the science behind soundproofing, we need to understand what sound is. Sound is nothing but the energy generated by vibration that travels through the air. Traveling from the source in the form of waves, it interacts with the air and objects along the way, causing them to create vibrations of the same frequency. 

Despite being slower than light, sound waves easily penetrate through objects with greater ease. Thus, advocating the need to insulate. 

At its core, soundproofing is all about reinforcing the objects of the home such as walls, windows, and doors with an extra layer of insulation to prevent the passage of sound waves.  

Having to penetrate through obstacles to reach the destination, the sound waves dissipate along the way and get dampened to a hardly audible degree.  

What are the Elements of Soundproofing?

There are four basic elements of soundproofing including, decoupling, absorption, mass, and damping.

Decoupling

Decoupling is simply disengaging or separating one element from another. In terms of soundproofing, it refers to segregating the ceiling frames to restrict the passion of sound. 

Absorption

In the science of soundproofing, absorption is the act of absorbing or soaking in sounds to insulate rooms. This is done by adding extra insulating materials such as foam in between the layers of the joists to make the system soundproof. 

The aim of adding insulating material is to absorb the sound waves and dampen the sound before it reaches the destination. Some common insulation materials are cellulose, fiberglass, recycled cotton, mineral wool, and open-cell foam. 

Mass

Mass plays a pivotal role in blocking sound. The greater the mass of the object, the harder it is for sound waves to penetrate through the medium.

This factor is used commonly in soundproofing and modern homes are built with heavy walls or walls of composite materials to make them soundproof. 

The addition of mass greatly cuts down the airborne sounds. However, it is not equally helpful in eliminating impact sounds. Some of the common materials used in adding mass to the walls are mass-loaded vinyl, plywood, cement board, and OSB. 

Damping

Damping is done through the aid of damping compounds. These are the materials with the ability to convert sound energy into heat energy. These materials are highly effective insulators and used commonly in modern homes.

Why is Soundproofing Your Home Necessary?

Soundproofing or insulation has become the essence of building modern homes. Modern homes are built to cater to the need to insulate. 

Besides this, valuing insulation during the construction stage greatly augments the overall value of the home. A properly-insulated home is your haven; A place where you can reside in peace. 

The importance of soundproofing gets amplified if your house is next to the highway or a busy street where traffic noises cause an unavoidable nuisance. Following are five reasons why you need to soundproof your home;

To Achieve High-End Privacy

Soundproofing is not only essential to keep unwanted outdoor noise away from the home, but it also improves privacy. By soundproofing your home, you can be sure your neighbors don’t get to hear your private conversations. 

To Avoid Hearing Problems in the Long-Run

Many ailments relating to the loss of hearing are becoming apparent with time. The main reason for this is the nuisance and sound pollution around us. 

Soundproofing is an effective way to safeguard your home from a sound population and alleviate hearing problems.  

To Improve Health and Wellbeing

There is a direct correlation between cardiovascular diseases and prolonged exposure to noise. Sound pollution has many ill effects on the human body and mind. 

Augments Effective Communication in the Home

In a common household, noise levels exceed 60 decibels on average. This obstructs good communication and gives birth to misconceptions. 

Elevates Property Value

Not to forget, soundproofing your home can also elevate your property value and is a great value-lifting measure for homes especially undervalued homes. 

Effective Ways to Soundproof Your Home

To soundproof your home effectively you need the right set of materials. Sound-absorbing acoustic tiles, rugs, sound-blocking doors, and upholstered furniture are all good materials to soundproof the home. 

Sound-absorbing acoustic tiles are usually used for the walls while soundproof inserts are the best for windows. There are also many ways to restrict the passage of sound by insulating ceilings and floors. 

Soundproofing is all about controlling sound’s quality and nature and restricting unwanted noise from the outdoors. This can be done by building modern homes with soundproof walls, doors, windows, ceilings, and floorings.  

Sealing Cracks and Crevices

Covering up the cracks and crevices makes up the core of window insulation. Soundproofing is only as effective as its weakest part and cracks can end up spoiling all the hard work and investment.

Cracks and crevices are usually around the borders of the doors, windows, and walls. The connection between walls and windows is where the majority of cracks lie.  

The best way to soundproof these cracks is by sealing them with acoustic siliconized caulking. This acoustic caulk hardens up in a matter of hours and seals the cracks for years to come.  

Besides this, you can also try sound dampening curtains, double cell shades, double-insulated glass windows, insulation foam, and window plugs. 

5 Ways to Soundproof Doors

Five popular ways to soundproof doors to make homes better insulated are described below;

Sound-Absorbing Paint – It is a special paint that can absorb the sound waves traveling through the doors. Found easily on DIY stores, it seems thicker to the naked eye and restricts sound waves to a relatively good extent. 

Foam Tiles – There are foam tiles easily found at the music stores that can be glued to the doors to make them soundproof. 

Mass-Loaded Vinyl (MLV) Layer – As an alternative to foam tiles, a layer of MLV can also be applied to the doors to help them absorb the unwanted noise.

Door Sweep – Sound waves travel through empty spaces and there’s a big cavity below the door that gives them an easy way in. 

Adding Door Panel – A door panel is an effective sound barricade as it increases the door mass and restricts the passage of airborne sounds. 

Walls, Floors, and Ceilings

There are both pre-construction and post-construction ways to soundproof walls, floors, and ceilings. Besides this, a little creativity also helps significantly. 

Perhaps the cheapest way to soundproof a room is by adding furniture on the flooring, bookshelves by the walls, and panels on the ceilings. 

All these hacks make the room better insulated as it serves as an extra layer of barricade for the sound waves. Similarly, wall art and paintings aren’t also a bad idea as they fulfill the purpose effectively. 

These tricks and techniques are all effective to restrict airborne sounds traveling across the rooms. However, specific materials such as acoustic mats and underlays are used to reduce impact noises. 

In terms of the ceiling, the best way to soundproof is by insulating the flooring above. This dual-purpose trick not only soundproofs the bottom room but also insulates the one above.
