What Are Acoustic Wall Panels?

Acoustic wall panels are products designed to reduce the reverberation (also known as echo) of sound in indoor spaces. They are usually large, porous materials that are carefully designed and placed in a room to reduce noise and echo. Acoustic wall panels usually consist of a sound-absorbing material or core. It is covered with a breathable acoustic fabric that helps attenuate sound waves and reflections.

Acoustic wall panels work by absorbing sound waves rather than reflecting them. Therefore, this greatly reduces reverberation and creates an acoustically more balanced environment. In addition, modern acoustic panels are designed to combine function with aesthetics. They can be used in virtually any environment or space, including recording studios, classrooms, offices, and other spaces where excessive noise needs to be minimized.

COOWIN’s acoustic panels have excellent sound absorption. In addition, it has the surface texture and color of natural wood, bringing a natural, original aesthetic to the space.

What are The Main Functions of Acoustic Wall Panels?

Modern acoustic panels usually have the following four core functions:

Reverberation Control

Reverberation time (RT60) is an important indicator of the indoor acoustic environment. It is the time it takes for the sound pressure level to decrease by 60 dB after the sound source stops emitting sound. Excessive reverberation time can result in muffled speech and distorted music.

Acoustic wall panels absorb sound rather than reflecting it back into the room. As a result, quality acoustic wall panels can reduce the reverberation time in an average room from 2-3 seconds to 0.5-1 second. This makes it easier for people to talk, listen to music and enjoy a relaxing atmosphere.

Noise Reduction

Prolonged exposure to excessive noise can lead to stress, sleep disorders, hearing impairment, and other health problems. Studies have shown that poor office soundproofing can make it difficult for employees to concentrate. It affects work efficiency. Acoustic wall panels can effectively reduce indoor noise levels by absorbing noise.

Measured data shows that a reasonably arranged soundproofing system can reduce office ambient noise by 10-15 decibels. Therefore, the use of soundproof panels in the workplace and office can effectively improve the efficiency of employees.

Enhancement of Aesthetics

In addition to their practical function, acoustic panels can also enhance the aesthetics of a room. COOWIN’s acoustic panels are both functional and aesthetically pleasing. Ordinary walls may look boring and uninteresting. Acoustic wall panels in different colors and surfaces can add sophistication and elegance to your room. In addition, acoustic panels can hide unsightly features on walls or ceilings, such as peeling paint, minor cracks, and other imperfections.

Energy Efficient and Environmentally Friendly

Many sound-absorbing materials also have good thermal insulation properties. In winter, rooms fitted with acoustic panels can realize energy savings by reducing heat loss. This not only improves the acoustic environment but also reduces the impact on the environment.

How do Acoustic Wall Panels Work?

To understand how acoustic panels work, you first need to understand the basic characteristics of sound. Sound is a mechanical wave that needs to propagate through a medium (such as air). When a sound wave encounters an obstacle, three main phenomena occur: reflection, absorption, and transmission. In an ordinary indoor environment, hard walls, floors, and ceilings cause most sound waves to be reflected. This creates what we often refer to as echo and reverberation.

Acoustic wall panels work to change this acoustic property. It works in several ways:

Porous Materials Absorb Sound Waves

When sound waves hit the acoustic panel, they enter the porous material of the panel and are trapped inside. A portion of the sound energy is converted to heat and gradually dissipated. This greatly reduces the amount of sound reflected back into the space. As a result of this process, echo and sound reverberation are significantly reduced.

The Role of Air Gaps

Air gaps are effective in increasing the absorption of sound waves, especially long wavelength or low frequency sound energy. This helps a lot in reducing echoes.

When an air gap is left behind the acoustic panel, sound waves will pass through the panel and partially diffuse. The sound waves then hit the surface behind the panel, reflect back, and pass through the panel again. This causes the sound waves to spread further. Therefore, increasing the air gap behind the installation of acoustic panels can double the noise reduction coefficient.

How to Choose The Right Acoustic Wall Panels

There are many factors affecting the selection of acoustic panels. It is recommended to consider the following aspects:

Sound Insulation Performance

The main index for evaluating the performance of acoustic panels is the Noise Reduction Coefficient (NRC). NRC is the core index for measuring the sound absorption capacity of a material. It represents the percentage of sound absorbed by a product. The NRC range is usually between 0.0 and 1.0, with higher values indicating better sound absorption performance. For example, 0.7 NRC indicates a performance of 70% noise reduction.

Concrete walls typically have an NRC rating of about 0.05, which means that 95% of the sound that hits the wall will bounce back into the space. Acoustic wall panels, on the other hand, can have an NRC rating of 0.85 or higher. This means that about 85% of the sound waves hitting the panel will be absorbed rather than reflected back into the space.

Environmental Performance

It is important that acoustic panels are environmentally friendly. A good-quality acoustic panel ensures that no harmful substances are released during use, which can be harmful to human health and the environment. You can check whether the relevant environmental protection test report of the product meets the national standard.

Aesthetics

Choose the color, texture, and style of the soundproof panel that matches the interior decoration style. This can not only meet the demand for sound insulation but also play a role in decorating and beautifying the space.

Durability

Choose acoustic wall panels with reliable quality and stable structure. In addition, for places that may be affected by humidity, high temperatures, and other harsh environments, you should choose soundproof panels with good moisture resistance and high temperature resistance.

Types of Acoustic Wall Panels

There are various types of acoustic panels, including polyester fiber, foam, wood, and so on. The following are the advantages of different types of acoustic panels:

Polyester Fiber Board

Good Sound Absorption: The NRC of polyester fiberboard is about 0.7-0.8. Its three-dimensional grid structure can effectively reduce sound reflection and transmission. Therefore, it can enhance the listening experience and comfort.
Good Durability: Polyester fiber acoustic panels are moisture-proof and mildew-proof. It has a long service life and does not require frequent maintenance.
Environmentally Friendly and Non-toxic: Polyester fiber acoustic panels are environmentally friendly sound-absorbing materials. It is made from recycled PET bottles and can be used in direct contact with skin.
Easy to Install: polyester fiber acoustic panels are lightweight. They can be easily pasted, fixed or hung in areas where improved sound insulation is required.

Foam Acoustic Panels

The advantage of foam acoustic panels is that they are economically priced. If you are on a low budget, foam acoustic panels are the way to go. Of course, its disadvantage is that it is less aesthetically pleasing. In addition, cleaning them is not easy.

Dust can easily get trapped in the pores of the foam, making it difficult to suck out with a vacuum cleaner. The relatively fragile nature of the foam can also cause the panels to be easily damaged during cleaning. Therefore, make sure to install them in a less dusty environment.

Wooden Acoustic Panels

Wooden acoustic panels are solid wood or density boards machined into a structure with regular holes. It not only absorbs sound but also has a decorative aesthetic. However, the durability of wooden acoustic panels is poor. In addition, most wood acoustic panels must be installed by professionals using complex tools.

Usage Scenarios of Acoustic Wall Panels

Generally speaking, acoustic panels can be installed on walls or ceilings. They are especially useful in businesses, restaurants, recording studios, classrooms, home theaters, and other places where clear sound is important. Below are their applications in various scenarios:

Restaurants

Poor acoustics can ruin the atmosphere of a restaurant. Too much noise can detract from the dining experience. In addition, people with impaired hearing or anxiety can feel very uncomfortable. The use of acoustic panels in restaurants can be effective in reducing noise. A restaurant with acoustic panels installed can make dining a pleasure.

Office

Soundproof panels are almost essential in modern office design. Poor sound quality in an office can result in employees being unable to concentrate. Good acoustic wall panels can improve employee productivity, concentration, and overall well-being.

Cinemas, halls, etc.

The use of acoustic panels in movie theaters or halls creates good acoustics. Without acoustic wall panels, events and gatherings are plagued by excessive noise problems.

Conference Rooms

Excessive reverberation can affect concentration and the quality of meetings. Excessive echo in meeting rooms can also lead to poor sound quality in calls, e-conferences, or video calls. Installing acoustic panels in conference rooms can effectively improve the sound quality and bring a better meeting experience.

How to Install and Maintain Acoustic Panels?

Installing acoustic panels is a quick and easy process. Usually, you need to mount the panels on the wall or hang them from the ceiling. You can install these panels yourself or contact a supplier for professional guidance and service. The installation process has the following main steps:

Preparing The Installation Tools

Before starting the installation, you may need to prepare the following installation tools:

Laser distance meter
Leveling device
Electric drill
Screwdriver set
Glue gun
Mask
Gloves
Goggles

Selecting Panel Location

Determining the panel mounting location is a critical decision that must be made carefully. Be sure to study the basics of panel mounting and the adjustment of acoustic panel materials. This will enable you to plan the installation position.

It is common practice to install it on walls and ceilings in locations opposite the main sound source. This is why you may see acoustic panels behind the TV in your living room. This is because surround sound speakers direct sound waves to the front of the room, where they need to be absorbed. This ensures a top-notch viewing experience. For the same reason, you can also place soundproof panels behind your sofa.

Some soundproof panels will be placed in the corner of the room. When installing them in this location, consider the ease of cleaning. This is because corners will accumulate more dust and will need to be cleaned more frequently over time.

Wall Treatment

You will also need to clean and level the surface of the walls before installing the acoustic panels. This will ensure that the substrate is firm, level, and free from dust, oil, and other impurities. If the base layer is not level, it may affect the installation of the acoustic panels and lead to a reduction in sound insulation performance.

Installation Method

According to the type of acoustic wall panels and their actual use, choose the appropriate installation method. Common installation methods include pasting, nailing, and hanging. In the installation process, follow the supplier’s installation instructions. This will ensure a firm and tight installation. In addition, the gaps between the panels should be as small as possible to minimize sound leakage. If necessary, you can also contact a professional for installation.

Sealing Treatment

In order to improve the sound insulation effect, you need to seal the gaps between the panels and the joints with the base after the installation of the acoustic wall panels is completed. Usually, we can use sealant, sealing strips, and other materials for sealing.

Use of Auxiliary Materials

In some cases, it may be necessary to use auxiliary materials to enhance the sound insulation effect. For example, when installing acoustic panels, sound-absorbing materials such as sound-absorbing cotton can be added behind the panels. These materials can further absorb and consume sound wave energy. For some places with very high soundproofing requirements, double-layer acoustic wall panels can also be used.

Maintenance and Care

COOWIN panels are durable and require little maintenance. All you need to do is regularly remove accumulated dust. The choice of acoustic products and materials will greatly influence how easily you can keep your panels clean. For example, other materials, such as foam, are more difficult to clean due to their lighter weight. If you choose wooden acoustic panels, they may require regular maintenance, such as sanding or painting.

Other Ways to Reduce Echo in a Space

For most people, acoustic panels are the most effective way to improve the acoustics of your home, office, or business. In addition, a combination of the following methods can better absorb sound and reduce echo.

Adding Soft Decorations

If you live in a noisy area, you should pay attention to how you furnish your home. Furniture and decorative items can also help absorb sound and make your home acoustically more comfortable.

For example, use soft fabrics instead of leather or latex for curtains and upholstery. Or add some extra cushions to your sofa. Decorative items such as canvas artwork can also significantly improve the sound absorption of your space.

Furniture Selection and Placement

Furniture placement and material selection also play a very important role in the acoustic treatment of a room. Fabric furniture, such as sofas, helps to reduce noise compared to wooden furniture. A bookshelf full of books can also be effective in reducing noise in a space. You can place them against a wall so that the sound-absorbing properties of the furniture can be utilized.

Carpeting

If you hate the sound of footsteps and the noise created when objects are dragged around the room, then carpeting is a good choice. When sound waves travel through a room and hit the floor, carpeting absorbs them rather than bouncing them back. Therefore, carpeting is one of the easiest ways to keep things quiet.

Use Fabric Blinds

The use of fabric products will reduce echoes in a space as the fabric absorbs sound waves rather than reflecting them. Offices and studios often use metal or wood blinds. While these materials are affordable and low maintenance, they don’t do much to reduce echoes. Therefore, replacing them with fabric blinds is a good option if you want to improve the noise level in your space. If you have a larger budget, noise-reducing window coverings can also be a very effective solution.
