Additionally, both are important to keep in mind when considering the people around you. Both are important for a pristine listening experience. It is also important to remember that great sound diffusion isn’t a matter of sound diffusion vs absorption. Bringing in an expert for an acoustic treatment room analysis can help you figure out the best place to do your listening. Your purpose in a room is one of the biggest factors in the placement of diffusers.Īnother important factor is speaker placement and where in the room your “sweet spot” is located. To understand where to place a sound diffuser for maximum efficacy, you have to know what you want out of your listening experience.Īre you setting up a home theater? Are you listening to playback in order to mix music and create high-quality masters? Are you an audiophile that wants to hear your record collection in all of its vinyl glory? Not every handyman will be familiar with these tools, so it’s wise to consult an expert.īut now that you know more about different types of sound diffusers, how do you know what kind you need and where to place them? Purposeful Placement These tools help calculate the lengths of wood required to address frequencies of sounds in the environment that you want to diffuse. Before you ask “do wood sound diffusers work?” you can rest assured that they do.īut to build a good skyline diffuser, it’s important to be familiar with what’s known as a sound diffuser calculator or an acoustic diffuser calculator. A skyline diffuser is called that because it looks like a city skyline from the side. They use wood columns of different lengths mounted on a wall for a similar purpose to a quadratic diffuser.
The benefit of this type of diffuser is that it provides even diffusion of sounds at a wide range of wavelengths whether those sound waves are on the high end or lower end. They will often use several vertical slats with diffusers calibrated for specific wavelength ranges. Quadratic diffusers are designed to diffuse sounds at many different frequencies. 2D diffusers usually look like half spheres and diffuse sound left and right and up and down.
1D diffusers look like half-cylinders and diffuse sound waves left to right if they are set up vertically and up and down if they are installed horizontally. Do you need a 1D or 2D diffuser? Is a skyline diffuser right for you? What does any of that mean?ġD and 2D diffusers are acoustic diffusion panels whose names describe the planes on which sound is diffused. Diffraction in acoustics involves a lot of nuances. The purpose of your listening environment will affect the types of sound diffusers you choose. Instead, they give a listening area a more full, complete sound. One of the benefits of using properly placed diffusers is that, because they don’t eliminate the sound waves that come at them, they don’t deaden the sound in an environment. Unlike sound absorption panels that are made of soft materials with lots of air pockets that prevent sound waves from bouncing back at you, a sound diffuser allows for the sound to reflect-but it breaks up the reflection so you don’t get a clear echo. When you hear an echo, that’s a sound wave bouncing off a surface and coming back to you. High pitched sounds have shorter wavelengths than deep, bass sounds. A sound’s wavelength varies depending on its pitch. That’s why your voice echoes more in some rooms than others.Īnother element of sound is that it comes in waves. Sound does the same thing, except every hard, flat surface can serve as a mirror for it. When you shine a light at a mirror, the light reflects back at you. In some ways, sound operates kind of like light. or anything, but some knowledge of the basics will give context. To understand what a sound diffuser does, you need to first understand a few principles of the physics of sound.

Often what you need is a well-placed sound diffuser.ĭiffusing sound can be harder for a layperson to wrap their head around than sound absorption, but it is essential to creating a sonic experience that is rich and full instead of flat and sterile.Įffectively using sound diffusers requires understanding not just what they are, but where to place them in a room to get the best results-no matter if you are listening for business or fun. Making a great listening environment isn’t necessarily a matter of soundproofing a room. “Good sound” often comes just as much from the listening environment.
It isn’t just the quality of the music or the sound mixing in a movie. While everyone has an idea of what having a room with “good sound” means, many people have never put thought into what it takes to create that “good sound.”
