Most of us out there, myself included up to 25 years ago, did not know the power of diffusion and I will tell you this, once you experience it, you will never go without it. He is so enthralled and impressed because his life has changed acoustically with the power of diffusion which happens with most people when they hear it. Now he’s adding diffusion to the rear wall.
ACOUSTICA THE MUSIC ROOM SERIES
We’re going to be doing a series of videos with my friend Bruce who added diffusion to his front wall. A diffuser has a lot of similarities to a speaker and I tell people that a diffuser is a musical instrument and you must use care in where it is placed within a room. It has a frequency response of its own, it has a place in the room it needs to be depending on the usage of the room. If you really look at the instruments that we have at our disposal in terms of acoustical treatment, the diffuser is like a speaker because it has a sound quality of its own. If sound strikes wood, you get a nice, smooth, warm, balanced tonal quality sound back into the room and that’s why I always tell people that a diffuser is a musical instrument. Softer woods are good selections for a sound diffuser material because remember sound takes on the characteristics of the surface that it strikes. We use a lot of cherry wood in our diffuser builds. The above shows a selection of the DIY sound diffuser kits we sell here. Some other softwoods such as alder, pine, and birch work well and are economical. Woods can be easily stained and sealed, they’re readily available in all parts of North America that I’m familiar with so it’s a good choice. Wood with its cost, ease of manufacturing, ease of build and selection, and there are so many great woods to choose from. Synthetics like plastics and glass are no good. All the materials that the Earth produces or that we produce from the Earth make the best sound. Why? The natural materials on this planet produce the best sound. Why? You look at all the major studios and you look at all the rooms in the world that have a history of good recordings for voice and instruments, they have lots of wood. Secondly, wood is a wonderful choice for a sound diffuser material. I don’t care what the literature says and I don’t care what other companies claim. It just jumps out at you when you understand what it really is like and hear it and understand it.Glass is an example of a surface that we do not want to use for anything that involves critical listening audio.įoam Is a Sound Absorption Technology and Not a Sound Diffuser Material Optionįoam is a sound absorption technology, not a sound diffuser material and you would never make a diffuser out of foam. It’s the sound I hear immediately in a room even if you have only one window, I will hear it. Glass sound is an example of the sound quality you do not want. You won’t be able to stand it for too long nor should you. If you have a tone control, turn the low frequency all the way down, maximize the treble and really listen to the reflections in your car. Most of the surfaces in your car are glass so you’re going to get a really good idea of what glass sound is. Listen to that sound, that’s glass sound. As a good example, sit in your car in your driveway and shut the engine off and leave your stereo on. It’s going to sound a little bit weird, but sound takes on the characteristics of the surfaces that it strikes.
Sound Takes On The Characteristic of The Surface it Strikes
I’ll always tell you what it’s supposed to be and I don’t really care what other manufacturers claim in order to sell a product. Do your own research and if you have any doubts pick up the phone and call me.
It makes me sick to see that because companies take advantage of the ignorance of people and market these things and put names on them just because that’s what people search for.
If you’re not aware of the differences in those technologies and you purchased a “foam diffuser” product and got it installed in your room, you’ll realize that the terms are misused. The use of foam as a sound diffuser is nothing more than manufacturing hype and misspeak in order to promote a product or technology that says sound absorption is sound diffusion. Questions range from what the sound difference between wood and plastic would be and whether you could ever use cardboard or foam as a sound diffuser material. Last week I was asked what sound diffuser material option I would recommend. What Sound Diffuser Material Do I Recommend? With the changes in technology and materials available, this blog has been updated from its original posting to reflect new information in regards to what sound diffuser material I recommend.
