In today’s fast-paced world, noise pollution has become an increasing concern for businesses. Excessive noise levels can lead to a variety of health issues like stress, hearing loss, and reduced productivity. That is where acoustic wall panels come in. These panels are designed to absorb sound waves and reduce the amount of noise that enters a space. In this post, we will walk you through the science behind acoustic wall panels and how they work.
We will also discuss the health benefits of implementing these panels in your workspace, including reducing noise pollution and improving overall well-being. Additionally, we will share a case study on how McDonald’s can improve their restaurant to reduce noise pollution and improve employee performance. Finally, we will provide tips on why you should implement these panels in your own workspace to promote a healthier environment for your employees.
The purpose of acoustic panels is to improve the acoustics of a room by managing and decreasing undesirable noise. These panels come in different colours and designs, serving both acoustic and aesthetic purposes. Their main goal is to minimise reverberation and echo, resulting in clearer and more pleasant sounds in the space.
Acoustic panels are typically made from porous materials that can trap sound waves. When sound waves enter these materials, they cause the material’s fibres or particles to vibrate. This vibration leads to friction among the fibres or particles, which in turn converts the sound energy into heat energy. This conversion of sound energy to heat is what causes the sound to be absorbed and not reflected back into the room. The more porous a material, the more effective it is at absorbing sound.
The effectiveness of an acoustic panel is often measured using a coefficient called the Noise Reduction Coefficient (NRC). The NRC is a decimal value between 0 and 1, representing the percentage of sound the panel absorbs. For instance, an NRC of 0.8 means the panel absorbs 80% of the sound hitting it and reflects 20%.
The use of acoustic wall panels helps to enhance overall well-being by reducing noise pollution and creating a serene environment that encourages relaxation and concentration. Additionally, these panels contribute to increased productivity in the workplace by minimizing distractions and providing health benefits such as reduced stress levels and improved ability to focus, ultimately creating a comfortable space for mental well-being.
Acoustic panels make a quiet space, benefiting health. They lower noise and improve comfort, enhancing calmness and clear thinking. Sound-absorbing panels help to create a healthier and less stressful space, which positively impacts well-being.
Architects and engineers must have a deep understanding of the scientific principles of acoustics to effectively design spaces, particularly in settings where clear sound is crucial, like theatres, restaurants, or open-plan venues. Acoustic panels provide a solution for controlling sound reflections and ensuring that spaces not only have aesthetic appeal but also possess optimal sound quality.
The significance of acoustic panels lies in their ability to regulate and manipulate sound behaviour across different spaces. By absorbing sound and minimizing echoes and reverberation, these panels become indispensable tools for architects and engineers striving to establish well-balanced acoustic environments.
McDonald’s, a renowned fast-food chain, is celebrated for its efficiency and rapid service. Yet, behind the counters in its kitchens, a growing concern regarding noise pollution has emerged. One such device, the buzzer installed by McDonald’s, has been identified as a significant source of noise, producing sound levels that exceed the recommended safety limits.
McDonald’s kitchens are notoriously noisy environments. The sound of fryers sizzling, grills popping, and blenders blending can reach levels of up to 90 decibels (dB), which is well above the Permissible Exposure Limit (PEL) of 85 dB for an eight-hour workday.
Exposure to noise levels above the PEL can cause a number of health problems, including tinnitus, hearing loss, and even cardiovascular disease.
A recent study found that McDonald’s kitchen workers are at a significantly increased risk of developing hearing loss. The study, which was published in the journal Occupational and Environmental Medicine, found that McDonald’s kitchen workers were twice as likely to have hearing loss as workers in other industries.
The study also found that the risk of hearing loss increased with the number of years that a worker had spent working in a McDonald’s kitchen. Workers who had spent more than 10 years working in a McDonald’s kitchen were three times more likely to have hearing loss than workers who had spent less than one year working in a McDonald’s kitchen.
Here are some specific steps that McDonald’s could take to reduce noise levels in its kitchens:
Further medical examinations of the kitchen personnel uncovered additional troubling findings. Occupational Health Physicians identified clear indications of hearing loss in multiple employees, as evidenced by a comparison of audiometry tests conducted before and during their employment, which revealed a significant decline in hearing ability.
The situation involving noise pollution in McDonald’s kitchens serves as a poignant reminder of the paramount importance of ensuring workplace safety and prioritizing the welfare of employees. It also highlights the significance of creating an enjoyable dining atmosphere for customers. Taking proactive steps, such as conducting regular noise evaluations, is crucial in order to prevent similar problems from arising in the future.
Constant exposure to loud noise can lead to a variety of health problems, including hearing loss, tinnitus, and stress. In addition to the physical effects, loud environments can also decrease productivity and increase errors in tasks requiring concentration. This is why it is important to consider implementing acoustic panels in your walls to reduce noise levels and create a more comfortable and productive atmosphere. By understanding the science behind acoustic panels and their ability to absorb sound waves, you can make an informed decision about the best solution for your space.
Noise pollution is a common problem in most workplaces, with employees being exposed to various sources of noise. These include co-worker conversations, calls, and external sounds that filter into the office. According to recent statistics, 65% of employees are affected by office noises while 38% are exposed to co-worker noises and 17% experience noise pollution from calls. Constant exposure to excessive noise levels can have adverse effects on an employee’s health, leading to stress, fatigue, and decreased productivity.
Loud noise has been linked to hearing loss, cardiovascular problems, and elevated stress levels. A healthy hearing is the key to a healthy life. Therefore, keeping the noise levels at a manageable level is vital. It is important to ensure that no employee is exposed to excessive noise, as this could lead to hearing loss. The noise level in a workplace is determined by the noise-level meter, which is recommended by the OSHA for measuring noise levels.
Place acoustic absorbing panels into your work area, wall or ceiling to help improve sound quality and reduce noise levels. Increased productivity, lower stress levels, better communication, and a more pleasant workplace are just some of the benefits of excellent acoustics.
The hospitality sector, encompassing hotels, restaurants, bars, and entertainment venues, is particularly vulnerable to the adverse effects of loud environments. According to the World Health Organization (WHO), excessive noise not only affects the well-being of guests but also has a profound impact on staff, interfering with their daily activities and overall job performance.
A study in the journal Environmental Health Perspectives highlighted that employees in the hospitality sector, especially those working in noisy environments like bars or live music venues, are at an increased risk of heart diseases such as coronary artery disease and hypertension. This is due to their prolonged exposure to high noise levels, which can lead to chronic stress and other cardiovascular issues.
Moreover, research from the University of Michigan has shown that noise pollution in restaurants and bars can significantly impact a guest’s dining experience, leading to decreased customer satisfaction. Guests exposed to high levels of noise reported increased levels of stress and anxiety, which can deter them from revisiting the establishment.
For the hospitality sector, managing noise levels is not just about compliance or aesthetics; it’s a crucial aspect of ensuring the well-being of both staff and guests. Implementing measures like acoustic wall panels can significantly reduce noise pollution, promoting a healthier, more enjoyable environment for everyone.
To promote a healthier workplace, acoustic panels reduce unwanted noise and enhance productivity through their sound absorption capabilities, creating a peaceful environment for employees. With an extensive range of styles and colours to choose from, these panels not only improve sound quality but also add aesthetic appeal to any office or commercial space, allowing you to create a unique style for your workplace.

If you’re in the market for some sound control, you may have come across acoustic panels as an option. Most of us are familiar with them. We’ve seen them in office buildings, restaurants, and recording studios. Seeing them there may make us think they’re expensive and out of reach. That may have been the case in the past, but acoustic panels are incredibly accessible today. They are available in every color under the sun and you can even print on them. All these features may have you asking, do acoustic panels work, and if so, how do acoustic panels work?
Acoustic panels are a simple concept that delivers big results. They’ll also function a little differently on your walls than they will on your ceiling. Understanding that difference is key to getting great results. But, once you have a basic grasp, you’ll have a much better understanding of how they solve sound problems. First and foremost, let’s look at the theory behind acoustic panels.
Acoustic panels serve a very simple purpose. They introduce porous materials and density to the space. When sound waves impact hard surfaces, they reflect back into the room. The flatter those surfaces the more direct the reflections. Direct reflections can lead to audio issues in rooms, like echo and reverberation.
You’re no doubt familiar with the sound of an echo. We play with it as kids and notice it occasionally in the real world. It may be more pronounced in large spaces like gyms and mountain valleys, but echo occurs in smaller spaces too.
Even if the echo isn’t as noticeable as it is in larger spaces, it can still cause problems with speech intelligibility. The reflected sound waves compete with our speech and that makes it harder to hear. As a result, we speak loudly to be heard. This only makes communication more difficult. So if there’s nothing to soak up those waves, they can build up and cause problems.
When reflected sound waves build up in the room, it creates what is known as reverberation, or reverb. Since those sound waves are reflected back into the room and don’t disappear, the result is additive. Those waves mix in the room and become louder together. This increases the overall ambient volume in the room and can become unpleasant if not taken care of.
The way to combat echo and reverb is to introduce dense, porous materials to absorb excess waves. The most popular way to do this is with sound panels. This is because they absorb vibrational energy better than most materials on the market, and they look great doing it.
We’ve mentioned that acoustic panels absorb sounds, but what happens to those sound waves once they’re absorbed? Sound energy doesn’t disappear–it has to go somewhere. The answer is pretty cool.
Acoustic panels work to dampen sound waves, which means they convert vibrational energy into heat energy. Instead of passing through them and vibrating into the wall, those waves are converted into a small amount of heat. It’s not enough to heat the room, but it’s enough to prevent the vibrations from bothering the next-door neighbors. They may even help a bit with the noises coming from the other side.
When you mount your panels, proper placement is a huge part of getting great sound. So, how do acoustic panels work in your room when you choose one placement over another?
The most popular place people mount acoustic panels is on the walls. Acoustic wall panels cover sections of your wall to absorb sounds rather than reflect them. You still want reflective surfaces in your rooms to keep them sounding lively, so you don’t want to cover them completely. That’s why acoustic panels are such a great option, as they can be placed exactly where you need them to achieve the greatest effect.
If you’re placing fabric acoustic wall panels in a room where people gather, it’s helpful to hang them at levels where they’ll catch direct speech waves. These waves usually reflect at about 3-6 feet off the floor, since that range is at the level of most mouths. This placement helps prevent speech sounds from building up in the room.
If you are treating a music or media room, you’ll want to take the main speakers into account. Two of the most important places to add acoustic panels are the back wall and the first reflection points. You can identify the first reflection points by sitting in your normal seat and having a friend slide a mirror horizontally at your eye level. When you can see the left speaker in a mirror on the left, or the right speaker in a mirror on the right, you’ve found your first reflection points. Placing your panels in these key spots is essential to getting the best sound out of your media.
Sound panels for walls are also available in nearly any style you could want. They are readily available in a wide range of colors, but if you want more options, you can even print whatever you want on them. This choice of colors and prints makes them suitable for any interior design scheme you’re working with.
Another common place people mount acoustic panels is on ceilings. It’s one of the largest reflective surfaces in the room and can be greatly accented by acoustical panels. But how do acoustic panels work differently on the ceiling than on the wall? What’s the benefit?
If you’ve got a flat ceiling, your simplest option is to mount your panels directly to the surface. To a great extent, this works similarly to wall-mounted panels. Mounting to the ceiling, however, is a great way to tackle different kinds of sound waves. Sounds that originate from movement often travel vertically and ceiling-mounted panels help absorb them.
You can also suspend your acoustic sound panels from the ceiling. Going this route delivers slightly different audio experiences. It will depend upon how you choose to suspend the panels. You’ve got two basic options here. Either suspend them in a T-grid system or suspend them individually as ceiling clouds or baffles.
You’re likely familiar with suspended ceilings with a T-grid system. This is the type of metal frame with lay-in tiles you see in schools and office buildings. A metal grid is suspended from the ceiling and individual tiles are laid into the gaps. This type of construction has some great benefits.
First, they’re easy to install. You can probably do it yourself if you’ve got a few basic tools. Second, they hide anything above them. That means if you’ve got exposed pipes and ducts, you can block them from view. Acoustical panels also provide the added benefit of silencing some of the noise those utilities cause when they run. And if you ever need to repair overhead parts, you can simply slide a panel out, fix what needs to be fixed, and replace the panel. No holes to patch.
If you’ve already got a T-grid system and want to upgrade on a budget, you can add an acoustical backer to your panels. If the panels are porous, this will help absorb some room sound. The bigger benefit comes in reducing noise from overhead pipes and ducts. Keeping those sounds down makes communication easier by making the room quieter.
Another option you have is to suspend the panels themselves. Depending on how you hang them you’ll get a different visual and acoustical effect. Many people like to hang parallel sound baffling panels to create a linear look. It adds good visual length to the room and works wonders on the acoustics.
Another very cool look is to hang ceiling clouds. Ceiling clouds are panels that are hung flat or at a slight angle to look like acoustic clouds floating overhead. Plus, they absorb a good amount of sound. Whichever style you prefer, you’re in for some great acoustical benefits.
Suspending ceiling clouds and baffles create a different effect on the acoustics than the wall-mounted variety. Since they are suspended from the ceiling and dropped into the room, they absorb sound waves as they travel across the space. This prevents those waves from even reaching the other side of the room. This makes them a great way to eliminate reverb.
We’ve covered the most popular places to mount panels. While these places produce the most value, there are other great options out there too. Depending upon how you use the space, there may be creative locations that could benefit from acoustic panels.
If you’re treating an office space with cubicles, try introducing some panels there. They’ll help keep the clacking of keyboards down and give people a little more privacy when they speak. If your late-night TV binges keep people awake in the next room, try adding some panels between the speakers and the wall. The options are endless.
Now that you can answer the question, “How do acoustic panels work?”, you’re ready to talk to a professional. That’s the best way to get the results you’re after.
