When it comes to the manufacturing of acoustic panels, Polyethylene terephthalate (PET) is the gold standard. It&#;s the sturdy felt-like material we all know and love for its performance, aesthetics and durability. But what is it? Where is it manufactured? And how does it work? This edition of the Acoustic Influencer is devoted to exactly those questions.
Consider this your PET Explainer.
Polyethylene terephthalate (PET)
What is PET?
Large-scale PET acoustic panel manufacturing is a relatively new sound-absorption solution born out of science that goes back to the s. PET panels are produced from 100% recycled plastic materials (bottles, packaging, etc.) using a polymerization process that creates a resin. A combination of heat and pressure turns that resin into sheets of fibres used to produce acoustic panels. Those panels can then be modified to meet specific performance requirements.
PET is renowned for its sound-absorbing properties, but is also really durable, water and mold resistant, can be dyed and shaped to meet design needs and is easily cleanable. Acoustic panels made from PET don&#;t degrade and can be recycled into other products, making them even more eco-friendly. They are also hypoallergenic, odour-free and non-toxic.
Where is PET manufactured?
The majority is produced in East Asia &#; places like China and Taiwan &#; although Europe and North America are increasing their own manufacturing capabilities. The PET products McIntyre works with come from China via Vancouver.
How does PET work?
It&#;s quite fascinating, it&#;s a bit science-y. PET panels normally have multiple layers and thicknesses. They often include a dense core layer and outer layers with perforations, which help to create air gaps and porous surfaces.
When sound waves hit those gaps and surfaces, they bounce around, effectively trapping them. The energy created by that bouncing is converted into heat at a molecular level by internal friction. The louder the sound, the deeper into the panel it penetrates, further messing with the wave molecules and creating more heat. That all works to reduce any sound reflection and deadening the sound.
Thickness also plays a role. Thicker panels absorb lower frequencies. In an office setting, those include things like HVAC systems and servers, while thinner panels tackle high-frequency sounds like ringing phones and office equipment.
Of course, It goes without saying that the wrong panels in the wrong places won&#;t work well &#;
the type, location and placement are paramount. That&#;s where sound engineers working alongside installation experts (that&#;s us!) plays a huge role in overall effectiveness.
The Acoustic Influencer is 100% absorbent. Unlike PET panels, any noise created by our newsletter is heard (and appreciated). So, if you&#;ve got something to add, please comment and share.
What do acoustic panels do?
Acoustic panels are designed to reduce noise levels and eliminate echoes in a room. It works by absorbing sound waves and preventing them from reflecting off of hard surfaces. This can help to create a more pleasant and less noisy environment. The term &#;acoustic panel&#; refers to any type of panel, both vertical and horizontal, that is used for this purpose.
Do you have a noisy office? Or maybe your home theater is too loud for comfort? If so, acoustic panels may be the solution for you! Acoustic panels help to absorb sound and reduce noise levels. In this blog post, we will discuss what they are , what they do, and how to choose the right ones for your needs. We&#;ll also take a look at some of the pros and cons of using acoustic treatment to solve noise issues.
Acoustic panels are large, usually porous pieces of material that are strategically designed and placed within a room to reduce noise and echo. They commonly consist made of a sound-absorbing material or core and covered in a breathable acoustic fabric. that helps to dampen sound waves and reflections. They can be used in almost any environment or space but are most commonly used in recording studios, classrooms, offices, and other spaces where reducing excess noise is important.
Acoustic panels work to reduce noise be removing excess reverberation, vibrations or echo within a space by stifling or muffling airborne sound waves. Their porous structure allows sound waves to enter the absorbing core and strip back excess frequencies to improve acoustic comfort. They also prevent the sounds bouncing off hard surfaces or structures such as walls, floors or windows.
There are a variety of panel types available, each with its own set of benefits and drawbacks. The most common type of consists of a mineral wool panel, which is made from rock wool or fiberglass. Mineral wool panels are effective at absorbing low-frequency sounds, but they are not as effective at absorbing high-frequency sounds. These are often either painted or wrapped in acoustic breathable fabric for a sleek finish. Recycled PET acoustic products have also gained popularity over recent years. These panels can also be covered with a fabric such as velvet or canvas and can be effective at reducing reflections and diffusing sound. Acoustic foam is also a great option.

Acoustic panels are not always required, but you will usually be able to notice a problem if there is one. Is your space feeling uncomfortable, loud or irritating? If you notice that the sound waves just don&#;t sound right, then acoustic treatment are a great solution.
They will help reduce noise, but only within the space that they are installed. They won&#;t effectively stop or block noise or transfer of sound between spaces.
Acoustic panels are an important part of any open plan office, recording studio, live music room, or home theater. They help to absorb excess sound and prevent noise pollution. There are many different types, and each has its own set of benefits.
One of the most common forms of acoustic panels is acoustic foam. It is constructed from an open-cell, flexible material that effectively absorbs sound. Acoustic foam may be made to complement any room&#;s decor because it comes in a number of colours and thicknesses. Because acoustic foam has the potential to catch fire, it shouldn&#;t be utilised close to heat sources.
The bass trap is yet another well-liked design of acoustic panel. Low frequency noises, which are frequently problematic in recording studios and live music venues, can be absorbed using bass traps. Typically, dense materials like fibreglass or rockwool are used to make bass traps. To increase their effectiveness, they can be put against walls or in corners.
Another kind of acoustic panel that serves to enhance the sound in a space is an acoustic diffuser. Diffusers can lessen echoes and produce a more realistic sound because they distribute sound waves rather than absorbing them. Diffusers often come in a range of sizes and forms and are made of wood or metal.
No matter what type of acoustic panel you choose, it is important to make sure that it is installed correctly in order to achieve the best results. If you are not sure how to install acoustic panels, we can provide a complete survey, supply and installation service for you.
The number of acoustic panels you would need would depend on the size of the room, the amount of noise coming from outside, and how much echo you want to reduce. In general, more acoustic panels will result in a deader space.
As a general rule of thumb, covering 30-40% of the wall surface area with is a good starting point to hear a difference. However, factors such as wall/ceiling surfaces and windows may require a unique approach. Ceiling panels are often the most effective sound absorbers and we recommend these for almost all projects, although not always practical.
If you are trying to completely block out outside noise, you will need more than acoustic panels than if you are merely trying to reduce echo in a room. The size of the room will also affect how many acoustic panels you need. A smaller room will require fewer panels than a larger room.
For open plan offices, there is a specified British standard which sets out guidelines for acoustic treatment in commercial building. Reducing noise in offices is around 70% of the work we do at Resonics.
In general, it is best to consult with a professional to determine how many acoustic panels you need for your specific situation. They can take into account all of the factors mentioned above and help you choose the right number of panels for your needs.
Our ears pick up on sound waves, which are vibrations that move through the air or any other medium. Numerous things, including but not limited to musical instruments, people speaking, electrical devices, and background noise, can produce these waves. Sound-absorbing materials can be used to lessen the quantity of noise that is present in a certain area.
Acoustic panels are one type of sound-absorbing material that can be used to reduce noise levels in a space. These panels are usually made of fiberglass or other absorbent materials, and are designed to absorb sound waves. Acoustic panels can be used in a variety of settings, including office spaces, classrooms, music studios, and home theaters.
One kind of sound-absorbing material that can be utilised to lower noise levels in an area are acoustic panels. These panels are intended to absorb sound waves and are often composed of fibreglass or other absorbent materials. Offices, classrooms, music studios, and home theatres are just a few places where acoustic panels can be employed.
If you&#;re interested in reducing noise levels in your home or office, acoustic panels may be a good option for you. There are many different types and styles of acoustic panels available on the market, so you should be able to find something that meets your needs and fits your budget.
Acoustic panels are a great way to reduce noise levels in any room, as well as improve the quality of sound. These panels are typically made from fiberglass or other absorbent materials and come in a variety of shapes and sizes. Acoustic diffusers are another type of acoustic panel that can help to reduce echoes by scattering sound waves instead of absorbing them.
