What Is the Difference Between Soundproofing and Acoustic Treatment?

Many people confuse the terms soundproofing and acoustic treatment. While many people think they are the same, they are two completely different processes.

Soundproofing is the process of blocking out noise and reducing the sound pressure between the source and the listener. Acoustic treatment, on the other hand, controls echo and reverberation by absorbing sound.

People often make the mistake of not getting the soundproofing they want. However, if you know enough about soundproofing and acoustic treatment, you can choose the right method.

What Is Soundproofing?

In everyday life, sound usually travels in one of two ways:

  • Sound travels through the air
  • Sound travels through solid structures

Sound can utilize the air as a transmission cutoff. For example, when you speak, you create sound waves, which then travel through the air to the other person’s ears. Therefore, to stop sound from traveling from one room to another through the air, you need an acoustic substrate.

On the other hand, the propagation of sound waves through solid objects is a bit trickier and only a few people really understand this. To make it easier to understand, we usually call it “vibration”.

To stop vibrations from bouncing off solid objects, such as walls, you need to separate them with soundproofing materials. These materials include sound-absorbing panels, high-density rubber mats, springs, and elastic channels.

In addition, outside noise can enter the room through windows, doors, walls, and even the roof. Likewise, the noise you make can travel outside your house and disturb your neighbors.

How Do I Soundproof My Home?

To avoid this, you need to soundproof your home. Soundproofing is the process of preventing noise from traveling into or out of a building. It involves installing soundproofing panels and other things that can block noise.

To keep a space quiet, you need to put up a barrier to keep the air out. Such barriers reduce noise by blocking sound waves from entering through any gaps.

One way to block noise is to have two doors or two walls with a gap in between. With two walls or two doors, they have more mass. And more mass means they block more noise. In addition, the air trapped in between forms bubbles that also help to block noise.

What Is Acoustic Treatment?

If you have a music studio or home theater, you most likely know what acoustic treatment is. It’s the process of making a room sound better so that the sound you produce is calm and pleasing to the ear.

It doesn’t matter how good your microphones or speakers are, if the room they’re in isn’t acoustically treated, they won’t sound great.

In addition, the size of the room in which the sound is emitted can have a big impact on how it sounds. The resonance of low-frequency sound changes dramatically depending on the length, width, and size of the area. The larger the room, the more echoes and noise reflections there will be.

Poor sound quality is caused by these echoes and reverberations. Therefore, if you are recording in a room that has not been acoustically treated, it will not sound good, no matter how well you record.

How Do I Perform Acoustic Treatment?

In order to treat the sound in a room, you need to place something that absorbs the sound at the point where the sound source is reflected. This way, the noise you don’t want will be absorbed rather than reflected.

It’s important to remember that the thicker the sound-absorbing material, the more effective it will be at absorbing noise. That being said, before you buy soundproofing materials, you should consider how big the space where you want to place them is.

If the room to be treated is large, it is best to purchase thicker and larger soundproofing panels. It can also help reduce reverberation time when the treatment is needed in a particular area. Reverberation time is the time it takes for the sound to drop to 60 decibels lower than it was.

Standing waves are the most important issue to deal with when acoustically treating a room. Standing waves are directly related to the size and shape of the room for a particular sound frequency. These standing waves are also known as “room modes”.

Sound waves can add up or cancel each other out as they bounce off the walls. When sound waves add up, the frequency of the sound waves becomes a little higher. On the other hand, when sound waves cancel each other out, they become less frequent.

Common Sound Insulation Materials

Acoustic panels are not the only things that absorb noise in acoustic treatments. The placement of items in the room can also help with this. Carpeting the floor can also reduce noise.

There are two common products used for acoustic treatment:

  • Porous absorbers
  • Resonant absorbers

In most cases, melamine foam or open-cell rubber foam is used as a porous absorber. The small holes in these materials are effective in absorbing noise because they create friction within each cellular structure.

The many small holes in open-cell foams make them excellent at absorbing a wide range of medium to high-frequency noises. However, it should be noted that they may not be able to absorb lower frequency sounds. We can judge the sound absorption of open-cell foams in several ways, such as:

  • Curvature
  • Cell size
  • Porosity
  • Density of the material
  • Thickness of the material

On the other hand, resonant absorbers or resonant panels work well at low frequencies. The range of frequencies that such materials can absorb is relatively small. They serve to reduce the resonance of sound waves when they are reflected.

Different Types of Soundproofing Materials

Different types of soundproofing materials have different uses. They also have different functions depending on where they are placed.

Drywall

The least expensive way to block noise is to use drywall. Its mass gives it strength and stops sound waves from traveling around.

The thicker the drywall, the better the soundproofing. To ensure that drywall has good soundproofing, make sure you find the thickest drywall you can find at a nearby store.

Soundproofing Panels

This material is perfect for blocking noise in places where a lot of people gather. This includes places like stores, offices, concert halls, and restaurants. Soundproofing panels are expensive and made from high-density gypsum board, which can successfully stop sound from traveling from one room to another.

There are also different types of soundproofing panels such as waterproof panels, fabric-wrapped panels, and perforated wood panels. These soundproofing panels serve a number of purposes, such as making speech clearer, absorbing sound, and limiting indoor vibrations. Although they are mostly used in commercial environments, they can also be found in homes.

Acoustic Foam Tiles and Panels

If you want to absorb sound effectively in a place, you need to soften any hard surfaces. By applying foam panels, you can achieve the effect of softening the surface. You can also use special tiles on the largest parts of the room, such as the floor and ceiling.

To prevent sound from traveling from one room to another, foam tiles and panels are usually applied to the walls between rooms. Alternatively, you can cut this soundproofing material to any size you need.

Polyester Fiber Acoustic Panels

Polyester fiber on this acoustic wall panel has excellent sound absorption and thermal insulation properties. And polyester fiber is also available in a variety of colors that can better decorate your house.

Even better, it also prevents dust and moisture from building up. Some acoustic panels come with adhesive tape on the back that allows you to stick them firmly to the wall.

Types of Acoustic Treatment Materials

There are many types of acoustic treatment materials and you can choose the one that suits you best.

Acoustic Film

There are various types of acoustic membranes on the market, and you can choose the one that best suits your needs. Using acoustic membranes will not be too heavy. This also means that they are more effective in converting sound energy into heat, resulting in less sound.

This material is usually used for ceilings, walls, and floors. It comes in two thicknesses, 3 mm and 6 mm. The use of this reduces airborne pressure and sound.

Acoustic Flooring

Acoustic flooring is used to separate the main floor of a room from the basement. Thus, it reduces incoming sound. In most cases, cork and rubber crumb can be used to make acoustic flooring.

Acoustic Panels

Soundproof panels can be installed on walls, ceilings, and other surfaces. They are excellent for calibrating, balancing, and controlling sound in a room.

As long as they are installed correctly, acoustic panels can be effective. They also cover enough space and surface area. In fact, acoustic panels look great and can decorate a house nicely.

Soundproofing panels come in a variety of shapes, colors, and styles. If you want to deal with the noise in your room and at the same time make it look good, then acoustic panels are one of the options you can consider.

Acoustic Foam

Studio foams are what most people call them. They are blocks of foam with prominent shapes such as chamfered, flattened, curled, pyramid, or wedge. Their main use is to improve the quality of recordings in studios and music rooms.

Acoustic foams utilize an internal acoustic absorption and recalibration concept. As a result, they do not block sound as well as other sound-absorbing materials.

It is worth noting that this sound-absorbing material is available in different strengths and thicknesses. Therefore, choosing the right location is very important for the function and usefulness of this material. In addition, you should also consider the number and type of surfaces to be covered.

Acoustic Fabrics

Acoustic fabrics are very thick fabrics. They are commonly used to make blackout curtains, recording studio blankets, and theater curtains.

Because they are thick and heavy, they provide a good noise barrier in large rooms and halls. Acoustic fabrics can also be used to line walls to make them more soundproof.

Why Do We Need Noise Barriers?

One place where people often need to block out noise is their homes. In fact, this is especially true if you live near a street with high levels of noise pollution.

One of the main purposes of soundproofing is to stop sound from traveling from one place to another. The most common way to accomplish this is to use materials that stop airborne and structure-borne noise. While the soundproofing process sounds simple, it’s more important than you might think.

Here are some important reasons why you need to soundproof your home:

More Privacy

If you work from home, or if your family is involved in childcare. Insulating your home from noise will help you get more done. This is because you won’t hear as many sounds that distract you.

But that’s not the only reason soundproofing your home is important. For example, if you need to talk about private information in a meeting, soundproofing will prevent your neighbors from overhearing what you say.

In addition, if you play music loudly in your home, your neighbors won’t be bothered or upset. This is because soundproofing blocks the noise you make.

Reducing Your Unwanted Noise

Installing soundproofing is a great way to prevent annoying sounds from traveling from one room to another. This is because soundproofing materials block noise by absorbing airborne noise with a thick material.

It’s important to remember, however, that soundproofing will only work if you seal all the cracks and crevices in windows, doors, walls, and other rooms. But if done correctly, insulation will make your rooms quieter.

Increase Property Value

Sometimes people need to sell their homes and move somewhere else. However, this can be difficult, especially if you live in the city center, near an airport, or near a busy street.

This is because people who want to buy your house will think twice if they hear that your house is near a noisy area. Installing soundproofing in your home, on the other hand, will allow you to show potential buyers that the interior is peaceful and quiet.

Improve Concentration

In a quiet and peaceful environment, you can better focus on what you need to do. This is especially important if you study or work from home.

The truth is that you can’t stop the people around you and your neighbors from making noise. However, you can stop these noises from reaching your room by using soundproofing materials. This way, you don’t have to deal with noise from the outside so you can focus on more important things.

The Importance of Acoustic Treatment

Music studios, home theaters, performance halls, and gyms are some of the most important places to soundproof. Because these are the places where people listen to sound sources, they need clearer, better-quality sound.

Why Is Acoustic Treatment Important?

Bass Absorption

If the walls are solid and thick, with no air space in between, there is a high risk of bass problems.

When recording audio, it is important to note the time at which reverberation or sound disappears. Nevertheless, you need to be able to distinguish the amount of reverb in the recording. If there is too much echo in the studio, it can cloud your judgment and make the sound quality worse.

In addition, reverberation can cause the frequency response to be uneven. As a result, your voice will sound lower than it actually is.

On the other hand, the size of the space you are in can also exacerbate the problem. Without any acoustic treatment, your room will never have the right sound setup for excellent sound quality.

Sound Diffusion

Sound waves do not bounce off the walls of a room when they diffuse. This way, you avoid problems when you start listening and when you need to listen carefully. In addition, diffusion improves the sound quality of videos, making them clearer.

Smooth Communication

Acoustic treatment materials absorb things you don’t want to hear, such as echoes and voices around you.

It makes your sound source sound clearer so that everyone can easily understand and talk to each other. This is why open-plan classrooms, offices, and lecture halls are the best places to place soundproofing materials.

Reduces Stress Levels

Being in a noisy place can make it difficult to concentrate, especially when it comes to work. One of the big problems people encounter is that they don’t want to hear noise because it makes it difficult to concentrate.

If you are in a noisy place, you will find it difficult to concentrate. However, if you have acoustic treatment installed, the noise level will be reduced and this will help you to concentrate on things better.

acoustic-wall-panels-13

Projection of Sound

Any sound emitted in a room travels in all directions. Solid objects around you will bounce most sounds. Some sound also travels in a straight line, which is direct sound.

If not handled properly, this reflected sound can change the pitch of the sound you initially make. To ensure that sound does not bounce and project, you should line the room where you are recording with soundproofing material.

Frequently Asked Questions About Soundproofing and Acoustic Treatment

How Does Acoustic Treatment Improve Sound Quality?

Acoustic treatment makes sound better by reducing the amount of background noise from the main sound. It absorbs sound waves and spreads them out, resulting in a better sound.

Do I Need to Cover the Whole Wall or Ceiling with Acoustic Material?

You do not have to have the entire wall or ceiling fitted with acoustic panels to reduce noise in a room. This is because you only need to lay soundproofing material in the areas where the sound waves directly reach.

For example, if you want to improve the sound in your home recording studio, you need to find out which walls the sound waves hit when recording. Once you know that, you need to place acoustic treatment materials in those areas. This way the soundproofing material will absorb the sound waves and echoes and reduce the noise inside the sound recordist.

Where in the House Do I Need to Block Out Noise?

Essentially, you need to keep any room where you think sound can pass through quiet. The same goes for the spaces between walls and ceilings, doors and windows.

By soundproofing these areas, you can reduce the amount of noise coming in and out of your home. Noises you don’t want to hear can be annoying. Therefore, keeping them out of your home is the best preventative measure.

Can High Ceilings Reduce Noise?

You can make your home feel bigger by raising the roof. Many home builders like to use high ceilings in their designs.

While such ceilings can make a room look nicer, they can make it louder. Because of the height of the ceiling, sound waves travel a longer distance.

With a bigger place, there is more echo and reverberation. This is not good if you want to record sound or keep it quiet.

acoustic-wall-panels-15

Difference Between Sound Insulation and Acoustic Treatment

Both soundproofing and acoustic treatment materials are important. Although they are very different, both can make the sound you produce sound better. But before deciding whether to use soundproofing or acoustic treatment materials, you should think about what you need.

If you don’t want outside noise to enter your building, or if you don’t want your noise to bother your neighbors, you need soundproofing materials. If you want to improve the sound quality when recording, acoustic treatment is the right choice.

That said, acoustic treatment is the best way to make sound sound better in large rooms with a lot of echo. No matter what the situation, soundproofing and acoustic treatment are important.
