Soundproof Foam VS Acoustic Foam

The misconception about foam being soundproof exists mostly because people lack the understanding of the differences between sound absorption and soundproofing.

It is natural to assume that if products like foam absorb sound, there will be none that is left to escape the room.

Unfortunately, sound is not like a fluid that gets absorbed and trapped in something like a sponge. The way sound behaves needs to be understood clearly here.

Sound waves are nothing but vibrations and when they strike a surface, they tend to vibrate it.

Sound does not ‘pass’ through a wall or ceiling but merely vibrates it. These vibrations are further transferred to the other side and that is how sound transfer takes place through walls, ceilings, and other surfaces.

1. Walls and Ceilings

The most common myth is that panels made of foam can be stuck on walls and will reduce the amount of sound from entering or leaving a room.

The foam that you see stuck on the walls of studios is not meant for soundproofing but is meant for sound absorption. The products that do the actual soundproofing in a studio are something else.

What You Should Be Doing Instead

You should first of all try to make your walls heavier. You can add mass to your wall by:-

Extra Drywall

Installing an additional layer or two of drywall will help to reduce sound transfer. A 5/8” thick drywall sheet weighs 2.31 pounds per square foot. That’s some serious mass and is a great substance for reducing sound transfer.

Coming back to foam, there are many varieties available and their densities vary depending on the type and grade. However, the foam would have to be several inches thick to match the mass of drywall.

Pros

Low cost.
Lots of mass.

Cons

Effort and workmanship required to install.
Involves modification of structures, so not an option for rented apartments.

Floors

Impact Noise
Airborne Noise

Impact noise is the noise caused as a result of footsteps or furniture being moved on the floor.

Airborne noise is the sound that is normally transmitted through the air and these include traffic noise, dog barking, neighbors yelling, and everything else.

New Trend for Soundproofing Your Home

The average city dweller spends his or her time surrounded by noise– traffic, television, cell phones, and unwanted office gossip. But people who want a quieter life are finding ways to outfit their homes with sound-proof accessories, such as curtains that mute noises from outside. This is one of several ways to make staying home much more peaceful and reap the health benefits of silence.

Noise pollution affects many people and homes, causing health effects such as stress and anxiety. There are many fancy methods to isolate yourself from sound, but soundproofing is expensive and typically reserved for technical uses, such as for a recording studio.

According to the World Health Organization (WHO), it is only safe to be exposed to loud noises for a maximum of 8 hours. Many of us who live in urban areas or noisy towns receive a lot more noise than recommended. Because of this, there has been a significant rise in home soundproofing through the use of soundproof curtains and other methods.

However, there are several simple home hacks you can use to significantly reduce the amount of noise you hear.

One popular way to achieve a quieter living space is through your furniture. When you have an empty room, sound bounces off the walls a lot easier since there is nothing to absorb it. These bouncing waves reach your ear and you perceive ‘sound’, but the simple addition of heavy and soft furniture can absorb a great deal of these waves. Add heavy tables and sofas with a lot of cushion to absorb the most amount of sound. Books also help and look great on your coffee table!

If you want to get fancy with your soundproofing you can add acoustic panels to your walls and ceiling. These are used mostly in studio sound booths during music recordings, but many manufacturers craft these panels for use in your home. These panels work much in the same way as furniture works– by providing a thick, soft and permeable surface which effectively absorbs sound waves.

Don’t Forget Your Doors!

You’d be surprised at how sound finds its way into our homes through the smallest cracks and spaces. One place we often ignore when we think about sound leakage is our doors. Gaps beneath doors let a considerable amount of noise through, but there is an inexpensive solution. Sealant tape can easily block these gaps without hindering your doors from opening or closing. A more expensive but permanent solution is a mounted seal that uses metal and rubber and lasts a lot longer than tape.

Reducing noise in your home will not only give you peace of mind, but is also attributed to many health benefits. Some of these include lower stress levels, better concentration, increased brain function, and greater focus for self-reflection. The benefits of good rest are also widely studied, and the solution is as simple as installing a set of soundproof curtains.

The Benefits of Soundproofing Your Home

Soundproofing is the technique of utilising insulation materials to minimise the noise passing through the walls.

Whilst many people think that soundproofing is only necessary for acoustically sensitive environments like recording studios, there are numerous positives to be gained from investing in soundproofing for your home. Whether it’s to provide you with a little headache relief from noisy children or to make your music practice room soundproof, so you don’t disturb the neighbors, there is always a good reason to consider soundproofing measures.

Privacy

If you want to avoid disturbing your neighbours and being disturbed by your neighbours at the same time, the best thing to do is invest in soundproofing your home. The experts at Metropolitan Insulation explain that privacy is a valuable thing that we often do not even consider until we don’t have it anymore, and one of the worst breaches of privacy is when you and your neighbours can hear each other. Private conversations can be overheard, music and loud noises can cause tension between you and the last thing you want is to fall out with someone who lives right next door to you.

Your home should be a relaxing, comfortable place to return to after a long day at school or at work, so it is essential to prevent the noise coming from both inside and outside of the house. You don’t want to worry about what your neighbours will overhear or what you may inadvertently hear from their side. By soundproofing your home, there will be no awkwardness or tension, so you can live side by side with your neighbours in harmony.

Comfort and Quality of Life

Soundproofing can significantly enhance the comfort of your home, from helping to provide the perfect sleeping environment to ensure that you are able to relax for a moment in private whilst the kids are particularly rambunctious. In order to achieve this ideal environment, you don’t even need to soundproof the whole house. By soundproofing the doors and windows of particularly noisy areas in your house like your kids’ bedrooms and the rooms where you like to relax, that is enough to create peace and quiet. No more stress, no more anger, and exhaustion caused by noise-just a happy home for the whole family.

How to soundproof an apartment door: Painless DIY Solutions

Why soundproof a door and who should do it?

If you’ve recently moved into a new apartment and discovered that on some nights you’re wide awake as you listen to your neighbours’ conversations in the hallway, your flimsy doors may be to blame.

As a light sleeper myself, loud noises from the hallway have kept me up on countless nights.

With the recent trend of people working from home, you may also be looking to dedicate a space for your new home office with optimal sound-proofing properties so you can work in peace.

If those situations sound familiar to you, it might be time to think about how you can soundproof your doors to get a good night’s sleep.

How they work and if they can be effective

Soundproofing a hollow door works just like soundproofing a room does.

The problem usually arises because most doors have hollow cores, often trapping air inside.

The trapped air then acts as an excellent medium for noise or sound, but a terrible choice if you want to keep the noise out.

Hollow core doors are the most typical interior doors used nowadays in houses.

Beneath its surface is an inner cardboard honeycomb core surrounded by a softwood frame.

Considering this thin surface and the air-filled core, there just isn’t much to block the transmission of sound.

However, you can minimize the sound transmission by adding sound-insulating material on the door, which will significantly help in creating a more peaceful environment in the comfort of your own home.

Continue reading to find out how you can soundproof an apartment door. Here are a few products readily available on Amazon for you.

Note that these methods will allow you to minimize the noise transmission but will not completely block out noise.

If you wish to get rid of any outside noise once and for all, you might want to look into getting a solid core door.

We will explore that option at the end of this article.

Acoustic foam

A reliable go-to product when it comes to soundproofing is acoustic foams.

When installed on your door, these foams block noise while absorbing sounds.

As a result, they can eliminate any echoes from the house.

Since they are originally designed to improve the acoustics of a music room, you can count them to reduce the amplitude of noise level.

The best part is, they don’t require any special skills to install.

Because they are self-adhesive, it will be a hassle-free process for you.

Negative Effects of Sound Pollution

Every sound in a structure can be traced back to its acoustical roots. Creaky door hinges are rusty, too tight or in need of a good oiling. Floorboards squeaking or groaning are either incorrectly fastened or not plumb or true.

As for ominous loud ticking clocks, either you’ve been watching too many scary movies or you have very thin walls with no acoustical insulation and thin drywall layers. This too can be easily solved with a variety of wall types from traditional staggered stud to new high-performance ultra-thin ZR walls.

Unintended Negative Effects of Noises

The impact of subway noise on surrounding neighbourhoods shows that increased cardiovascular disease is related to sleep disorders caused by rail noise in urban areas. While most spooky sounds are low frequency noise, subways do create a wider variety of noises than wind turbines or deep footsteps, thereby having a wider and deeper range of effects. These are similar to having a spooky bad dream including, but not limited to:

Increased heart rate
Lack of deep REM sleep
Increased blood pressure
Elevated anxiety and stress levels

Last, but not least, is our favorite means of long-distance travel, airplanes. Because of new engine designs, noise from aircraft is getting better with each generation. Nevertheless, there is still a significant impact on local environments and the people living there. Similar to subway noise, physiological issues include:

Cardiovascular issues
Cognitive issues in children
Elevated anxiety
Decreased attention spans due to sleep deprivation.

Soundproofing and Acoustic Treatment: What’s the Difference?

Sound can be divided into two types: direct and indirect. Starting from the source, the sound travels in outward directions all around.

Direct travels in a straight line, whereas the reflected or indirect, randomly bounces in the room and between its surfaces.

Indirect sounds are echoes, reverbs, vibrations and similar. Direct sound remains the same, but the reflected change the original sound.

The change is either good or bad, depending on the size of the room, and its properties.

What Is Soundproofing?

The purpose of soundproofing is to block or minimise the level of sounds, both those traveling in and outside of the room.

So, the main idea is to have the sound focused – do not let the desired one get out, and, at the same time, do not let the unwanted ones come in!

This can be done either by blocking or sealing.

Sealing refers to all those tiny gaps, particularly in windows and doors.

What Is Acoustic Treatment?

Quite opposite from the previously mentioned, where the main idea is to block the sound, the purpose of acoustic treatment is to control the sound.

This particularly refers to indirect sounds, such as echoes, vibrations and similar.

So, it’s about controlling the sound that’s exclusively inside the room.

Soundproofing or Acoustic Treatment – Which to Choose?

Before you get down to business, be sure to know what exactly are you looking for? Do you want to reduce the echo?

Or you want to block all the sound except for the one you are making?

These are some of the questions you have to answer so that you know what the problem you have to deal with is.

Besides this, the dimensions of your room, as well as its shape are key factors.

If it’s in a building, that means dealing with numerous outside sounds as well.

The simple evaluation of the acoustic properties of your room is the best way to decide what you need.

Sometimes the help of a professional is needed in order to adjust the room as best as possible.

QUIET, PLEASE!

ACOUSTIC DESIGN FOR NOISE CONTROL.

State-of-art acoustic design can dramatically reduce sound transmission through shared walls and street-facing windows.

Today’s new homes, with their open-concept designs, quartz countertops, tile and hardwood floors, high ceilings, TVs mounted on walls and large floor-to-ceiling windows, are being embraced by builders, architects, renovators and homeowners alike for their clean, modern and minimalist ambience. But while these designs are pleasing to the eye, they are not necessarily pleasing to the ear.

A few decades back, heavy drapes on windows, carpeting on the floors and bulky furniture did much to deaden echoes in large rooms and suppress noises from other parts of the house. By contrast, modern open-concept design and bare floors promote echo-y spaces and room-to-room noise, with little regard for acoustics.
