Acoustic panels control echo and reverberation in a room. Most commonly used to resolve speech intelligibility issues in commercial soundproofing treatments. Most panels are constructed with a wooden frame, filled with sound absorption material (mineral wool, fiber glass, cellulose, open cell foam, or combination of) and wrapped with fabric. Acoustic Panels are also referred to as Sound Absorption Panels, Soundproof Panels, or Sound Panels.

Acoustic panels are a solution to noises that distract from your listening pleasure, whether you’re talking on the phone, recording music or shooting a video. But, how they work exactly, and how to set them up optimally is not something you would know right off the bat.

There are two types of sound: direct sound and reflected sound. Reflected sound arrives at our ears later than direct sound, even though it started out at the same time. Because it’s traveling farther. Also, a wall is only one flat surface -there are at least six in the average room-, and that’s a lot of reflected sound.

Reflected sound creates destructive Interference patterns that change the original sound wave. Here’s the problem: Original sound waves are distorted by strong later-arriving reflections.

Also, sound travels really fast, about 1130 feet per second (344 meters per second). A sound wave will bounce back and forth between these two walls about 60 times in one second. Sound travels so fast, it fills a room almost instantly. This is also only one bounce angle – every room has thousands.

There are two acoustical tools – an absorber to reduce the strength of sound bounces. To a sound wave, an absorber looks a little like a hole in the wall. So, some of the energy doesn’t come back.

An absorber works by reducing the strength of reflected sound that would otherwise cause more destructive interference. But, if we use only absorbers in a room, it makes it sound dull and unnatural.

Historically, humans don’t like overly-absorbent rooms. So – let’s use the second of our two acoustical tools – the curved-surface diffuser. It also reduces the strength of sound bounces.

A diffuser works by scattering the sound reflections in different directions, smoothing out destructive interferences throughout the room. Room acoustics are greatly improved using

A combination of absorption and diffusion. It’s all about reducing those flat-surface reflections.

Use a combination of absorbers and diffusers, and your room will sound a lot more natural. With that said, it brings us to the different types of acoustic panels.

Acoustic panels are a solution to noises that distract from your listening pleasure, whether you’re talking on the phone, recording music or shooting a video. But, how they work exactly, and how to set them up optimally is not something you would know right off the bat. So, I put together this article through the research I have done to answer these key questions.  So, what are acoustic panels and how do they work? Acoustic panels are installed to improve the sound within a room. There are two types of acoustic panels, diffusers, and absorbers. Diffusers stop the sound from reflecting off walls and ceilings, whereas absorbers absorb the sound waves as they hit them.  Exactly where to place them needs a bit of explaining. As well as, more detail about what they are made from and how they work. So, read on to discover the answers to these and more tips related to acoustic panels.  Before moving on it is important to note that acoustic panels are also called sound absorption panels, soundproof panels, or sound panels.  Where Do You Place Acoustic Panels? Before answering this question, you need to know a bit of sound theory to get the best sound quality for your room using acoustic panels. It is a common misconception that acoustic panels reduce outside noise from the environment. But, this is not the case. I will cover this topic in more detail towards the end of the article.  For now, I will explain how sound behaves in a room. So, that you can troubleshoot sound issues that come up yourself when installing acoustic panels. After that, I will explain step by step how to find the best place to put your acoustic sound panels to get exceptional sound quality in your room.  How Does Sound Behave in a Room? bounced sound Let’s talk about “Acoustics”, which is basically “how sound works in rooms”. It may seem complicated, so let’s make it simpler. Most rooms have flat walls and flat ceilings, and sound bounces off of these.  So How Does That Affect the Sound? There are two types of sound: direct sound and reflected sound. Reflected sound arrives at our ears later than direct sound, even though it started out at the same time. Because it’s traveling farther. Also, a wall is only one flat surface -there are at least six in the average room-, and that’s a lot of reflected sound.  But Why is Reflected Sound Bad? Reflected sound creates destructive Interference patterns that change the original sound wave. Here’s the problem: Original sound waves are distorted by strong later-arriving reflections.  Also, sound travels really fast, about 1130 feet per second (344 meters per second). A sound wave will bounce back and forth between these two walls about 60 times in one second. Sound travels so fast, it fills a room almost instantly. This is also only one bounce angle – every room has thousands.  How Can Acoustic Panels Be Used to Improve Sound Within a Room? There are two acoustical tools – an absorber to reduce the strength of sound bounces. To a sound wave, an absorber looks a little like a hole in the wall. So, some of the energy doesn’t come back.   An absorber works by reducing the strength of reflected sound that would otherwise cause more destructive interference.
