Acoustic treatment has four main goals: To stop standing waves and acoustics from affecting the frequency response of your sound control room i.e cinema, recording studio, office etc. To decrease modal ringing in small rooms, and reduce reverb time in larger spaces such as halls, churches, and auditoriums.
Full Answer
What type of acoustic treatment should I use?
Personally, I would choose to use the broadband fiberglass acoustic treatment because of the more level frequency response and also more absorption in the low frequencies. When it comes to acoustic treatment it’s really the low frequencies that we’re concerned with.
How much acoustic treatment does my room need?
The closer it is to #2, the less acoustic treatment you will need in general, although virtually any room will still benefit from a little. If you need some reference points to hear the difference between good and bad acoustics, perform the clap test in a wide variety of different rooms, and take notice of which types tend to sound best.
How can I reduce the acoustics of a recording?
By positioning the mic as close to the instrument as you can ( without ruining the tone )… You increase the portion of direct sound from the instrument, while decreasing the portion of reflected sound from the room…thus minimizing the impact of the acoustics on the recording. To take this concept one step further, you can also try… 2.
Does soundproofing count as acoustic treatment?
And while soundproofing can definitely be incorporated as part of your acoustic treatment plan, it’s not technically acoustic treatment in itself. So if you want to learn more about soundproofing, check out this post instead: Otherwise, let’s continue… Too often, when novices first hear of the supposed benefits of acoustic treatment…

Does acoustic treatment reduce noise?
Acoustic foams are installed to reduce noise pollution as they remove echoes and background sounds not by blocking the sound but by absorbing it. Acoustic foams are used to control the reverberation sounds make and this is quite different from soundproofing.
What does acoustic treatment do?
Acoustic treatments are solutions that help to absorb or diffuse sound to improve the acoustic quality of a space. These treatments come in various forms, and some facilities may need multiple types of treatments to achieve the ideal acoustics for the space.
Do acoustic panels reduce bass?
Acoustic panels are sound-absorbing panels that are used to absorb middle and high frequencies of sound in a room, which helps keep a check on reverberation. Bass traps are also sound panels, but they remove low-end frequencies that acoustic panels cannot absorb.
Does acoustic treatment make a difference?
When done right, acoustic treatment can turn a muddy sounding room with poor midrange definition and erratic bass response into one that sounds clear. Individual notes are much easier to perceive in a treated room without the reflections bouncing around off of hard surfaces, which makes music more enjoyable.
What is the difference between soundproofing and acoustic treatment?
Soundproofing is intended for minimising the level of sound that passes through the walls both ways by building it with heavy and dense material. Acoustic Treatment is intended for controlling the sound reflections INSIDE the room for making better sounding recordings.

Your Invisible Enemy: Acoustic Distortion
Okay, so you’ve seen me reference distortion and early reflections a few times already. Now it’s time to dive a little deeper into what exactly you’re fighting against. In an effort to explain this loaded topic a little better, I’ll break up every type of common distortion individually.
Where To Start Treating Your Studio
Now that we understand our enemy a little better and we’ve taken an in-depth look at all the forms of sonic distortion, it’s time to strategize our defense.
Advanced Treatment Methods
I know that some of you are itching to know what to do after these basic first treatments. Let’s get into some more advanced tactics to take as you progress on your treatment journey.
Finding A Balance
The key to tending to your studio acoustics is not to overdo it! Let me tell you, it’s definitely easy to go a little overboard with acoustic panels, bass traps, and diffusion panels.
Conclusion
So, you know your enemy. You know the enemy’s plan of attack. You also have your own strategies of defense. Luckily, this is a battle that can be won over a period of time, so there’s no huge rush.
Why do we need acoustic treatment?
The main reason we need treatment is that we have to listen to the sound in rooms. It’s the rooms that are the problem.
How to reduce the size of low frequency waves?
In order to reduce the size of the waves we start by building walls a certain way and using the correct amount of acoustic treatment materials.
What frequencies can a diaphragmatic absorber go?
Because of its mass and depth, you can build the unit to go after frequencies as low as 30 Hz. Diaphragmatic absorbers are broadband meaning they cover a range of frequencies. Therefore the diaphragmatic absorbers from Acoustic Fields are broadband for lower frequencies starting at 30 Hz. and going through 300 Hz.
What are the two types of sound energy?
There are two types of sound energy within our rooms. We must understand these two basic types of energy in order to design and use the correct type, amount, and position of the correct acoustic treatment materials. The first energy type is low frequency. Low frequency or as people say “bass” is that energy that comes from your neighbor’s stereo into your dining room while you are eating with friends. Its the energy produced by the garbage truck as it rolls down the street setting off the parked car alarms. It is the energy coming from a car stereo that causes the license plate to vibrate off its mounts on the car next to you at the stop sign. All energy below 100 Hz is Low-Frequency energy.
What is low frequency energy?
Low-frequency (waves) science is all about vibration management and sound attenuation or sound absorption. Vibration management is the science we use for waves (low-frequency energy) to keep them inside the room and not traveling to the neighbor’s house or to our parent’s bedrooms.
Why are waves reluctant visitors?
The waves are reluctant visitors since they don’t fit within the room dimensions and rays bounce around everywhere like children on sugar. The waves can try and stay in the room all the time producing distortion or they can leave the room and bother the neighbors.
What materials can be grouped together to achieve certain rates and levels of absorption for middle and high frequency?
Also there are numerous cotton and synthetic materials that can be grouped together to achieve certain rates and levels of absorption for middle and high-frequency absorption. There are also numerous building insulation material types that many companies use to create middle and high-frequency absorption “technologies.”.
What is soundproofing treatment?
Soundproofing is used to prevent sound from entering or escaping from the room and is usually done to prevent noise complaints (from neighbors) or to prevent outside noise e.g. traffic noise from being picked up by a microphone.
Why do we use diffusion in acoustic tiles?
While that’s the intended goal of acoustic tiles, diffusion is used to spread the sound out evenly maintaining the balance of the room. It doesn’t reduce reflected sound as acoustic tiles do, instead of retaining any natural reverb the room might have while dispersing the sound evenly throughout the room.
How to improve sound in a room?
Acoustic treatment such as acoustic tiles, panels, and bass traps can be used to further improve the sound of the room. Identify the first reflection points in your room first (side walls) and focus on the corners of the room and ceiling directly above you.
What is the science of sound?
The term ‘ acoustics ‘ refers to the science of sound and this includes: How sound travels from the source (e.g. the acoustic guitar) around a room. How the environment e.g. the characteristics of the room influences the sound (probably a much bigger factor than many realize) How sound is first detected e.g. by the ear, a microphone, or both, ...
What is chasing tone guitar?
We, acoustic guitarists, especially when it comes to recording, are always chasing tone. This often leads to discussions on body shape and tonewoods, strings, including gauges and materials, picks, microphones (if recording), and of course playing technique.
How is sound detected?
How sound is first detected e.g. by the ear, a microphone, or both, and then interpreted by the brain. Acoustics is a branch of physics, referred to as acoustic engineering, and those who undertake education in acoustics can earn a master’s degree.
What happens when two audio signals blend together?
Some of the frequencies of both the direct and reflected interact with each other. Some frequencies are ‘in phase’ e.g. the waveforms of the two combined signals are aligned, causing the signal to increase in amplitude aka volume.
Acoustic Treatment: Why Bother?
Before getting into specifics, let's remind ourselves why we might want to consider some acoustic treatment for our studio.
Ok, So What Can We Use To Help?
So now we've established why we might want to consider using acoustic treatment, what form does this actually take?
Stage 2: Practicalities
In this section we're going to offer a basic approach to how you might treat your room. Of course, every room is different, and ideally needs its own personalised treatment to deal with its unique problems.
The Final Word
Hopefully by this point you have an understanding of why acoustic treatment is used and what it often entails. You should also have a few ideas and a starting point for thinking about how you might apply it to your own studio.
How to test acoustic treatment?
An easy way to test where you should place your acoustic treatment is by using a mirror or the camera on your phone in selfie mode. Get someone to help you hold it on the surfaces where you think there may be reflections and then if you can see your monitor speakers that’s how you find the reflection points.
What is rear wall acoustic treatment?
Rear wall acoustic treatment. Traditionally in professional recording studios, you would actually have diffusion on the rear wall but that’s really expensive to do, generally diffusive panels are expensive to make and manufacture.
How to get rid of bass resonance?
The easiest way to treat bass resonances is by using bass traps in the corners of your room because this is where the bass builds up where two boundaries meet. So where the two walls and the ceiling meet you’ll have three different points meeting and it therefore creates big bass build-up. So you’ll want to put bass traps (thick acoustic treatment) in the corners of the room. This can really effectively absorb that low-end and hopefully get a flatter response across the frequency spectrum. When you’re working with the corners of your room you generally want a kind of triangular shape where you use loads of treatment that goes right into the corner and the easiest way to do that is by buying bass traps.#N#The Bass traps I would recommend are the Tri-Traps from GIK which are triangular shaped floor to ceiling traps that you can just add to the front and rear corners of the room. The GIK panels are triangle shaped and they’re full of material going from floor to ceiling. This is the most effective way to treat the corners, but you can also use air gaps. By just adding air gaps of about 5 to 10 cm (2 to 4 inches) behind the absorbers whether they’re a flat panel, corner trap or ceiling panel you can absorb a lot lower frequencies than you would be able to, compared to if the panel was just flat on the wall.
Why is it easier to hear EQ tweaks?
It gets so much easier to hear small EQ tweaks because you’re in a much flatter sounding room. Also, your mixes are going to translate better because your room isn’t tricking you into thinking that there’s too much or not enough bass for example.
Is a control room a good sounding room?
It’s just a good sounding room with a bit of treatment. Whereas the control room (where you do the mixing) we’re trying to create a reflection free zone. To do that we need lots of absorption around the mixing area. So generally in a home studio environment if you’re working in one room you treat it for mixing.
Is acoustic treatment good for home studio?
Acoustic treatment for home studio. If you’re going to do anything to improve the sound of your recordings and make mixing easier and more enjoyable then doing room acoustic treatment is the way to go. It’s worth spending a bit of money on your home recording studio acoustic treatment to get a professional standard.
Why do walls have acoustic panels?
Acoustic panels are the major way that reflections are kept from bouncing around the room. If your walls are hard (meaning there’s no absorption), these reflections are going to cause certain frequencies to cancel themselves out as they bounce around, causing those unwelcome dips and peaks in the room response as well as an uneven reverb decay time.
Is it expensive to soundproof a recording room?
While soundproofing the space where you have your recording gear set up can be an expensive and time consuming proposition, treating the acoustics of your room luckily can be quite the opposite. Believe it or not, it’s not that expensive and can be done in only a matter of hours if you have all the building blocks on hand.
What does acoustic treatment do?
When done right, acoustic treatment can turn a muddy sounding room with poor midrange definition and erratic bass response into one that sounds clear. Individual notes are much easier to perceive in a treated room without the reflections bouncing around off of hard surfaces, which makes music more enjoyable.
Why do we need to acoustically treat our rooms?
There are many practical reasons why you might acoustically treat your rooms. It won’t reduce sound transmission in and out of the room like soundproofing, but it can reduce the acoustic energy in the room by absorbing sound that would otherwise bounce around the space.
What is soundproofing treatment?
Acoustic treatment and soundproofing are two different applications for two very different problems. Soundproofing basically refers to blocking noise. We all value peace and quiet, and our own privacy, and the reality is that everyone can benefit from soundproofing.
Why is acoustic environment important?
Our acoustic environment is tremendously important: it affects our mood, our health, and our ability to do our jobs. When we’re indoors, the building itself and the room we’re inhabiting define our acoustic environment. With the right materials, we can influence that environment, but the hows and whys require a little knowledge.
What is the best way to improve a room's frequency response?
Once you have a baseline measurement of your space, then you can determine what kind of treatment will improve the room’s frequency response. Typically this would involve a combination of broad frequency absorption panels, bass traps, and diffusion. The first things to consider are broadband absorbers and bass traps.
How to block airborne sound?
The primary strategy for blocking airborne sound is to add a layer of dense, heavy material to problem surfaces. These materials are often used in multi-layered assemblies so that sound will not penetrate or pass through. Mass-loaded vinyl (MLV) is common.
Do foam tiles reduce reverb?
However, thin treatments like foam tiles, blankets, and mats do nothing to control low-frequency reverb or reflections, and the “hand clap test” won’t reveal that discrepancy. All materials will absorb, reflect, and allow sounds to pass through simultaneously.
Sound Energy Two Types: Low-Frequency and High Frequency
Waves & Rays in Our Room
- Waves and rays do two main things in our room. The waves are reluctant visitors since they don’t fit within the room dimensions and rays bounce around everywhere like children on sugar. The waves can try and stay in the room all the time producing distortion or they can leave the room and bother the neighbors. However this staying and leaving requires different technology desig…
Measuring The Noise
- We have explained that low-frequency energy (waves) are different than middle and high-frequency rays which resemble sunshine. This difference must be reflected in the design of the barrier we choose to build. Our first step is to measure the noise. We measure the noise over a seven day time period since you will be using the room all the time. We can take these measure…
Noise Barrier Technology
- For noise barrier technology that is composed of lower frequencies, we need to design the barrier construction in a certain way. We start with the external side or the side facing the noise. We need to use the densest material on the side of the wall that is facing the noise source. If the garbage truck is waking you up in the morning, then the barrier that we will build to keep the low-frequenc…
Low-Frequency Treatment Types
- Helmholtz
Low-frequency energy has three treatment types. There are Helmholtz, membrane, and diaphragmatic. Helmholtz is a tuned absorber technology that has a tuned port or slot in its top. The width and dimensions of the slot work with the body or cylinder of the absorber with its dept… - Membrane
A membrane absorber is a cousin to diaphragmatic. Firstly a membrane absorber has a membrane that has a certain density or rigidity. Secondly the membrane is joined to a cabinet with a certain depth and mass. Third the depth of the cabinet determines how low in frequency the u…
in Conclusion
- Sound treatment is based upon the frequency and amplitude of the energy you are trying to manage. Whether we are trying to minimize noise (sound) from leaving the room and bothering others or we’re trying to keep the garbage truck noise from waking us up in the morning, we use barrier technology between our ears and the source of the noise. Similarly if we are dealing with …
