    I recently had my fence replaced with Cedar wood. I had a lot of left over planks and scraps and made some panels and also just straight up attached the planks directly to the wall. It immediately made the room tighter. I thought it was placebo effect but this video justifies my actions. Thanks!

    Whatever wood, or any material, that you introduce is going to add it's own sound to the room, because it will vibrate. Freestanding wood is really going to add it's own sound. It's fine if you happen to find something that permanently colors the sound in a way you permanently like. It will drive you nuts if it's not.

      Trevor Cox, professor of Acoustic Engineering, writes in one of his book that a violin maker would be fortunate to find a wood which resonates. If it does it's due to heterogeneous presence of small wood cells in the wood. It matters for a violin, which produces sound, but amount of energy coming to a wooden plunk's cells is barely enough to make it resonate.
      As for structural resonance of such wooden plank it can be far outside of the audible range.

    Do you have advice for treating rooms with slat and plaster walls? I like the idea of leaning pine boards against the wall because the plaster won't bear much weight. I have foam up not because it's ideal, but because it's all the walls can support. Now the room sounds very dark.

    My suspicion is that the wood added mass to the wall membrane, changing the walls resonance. That or there was some bad slapback echo maybe.
    I like the look of wood. Wooden diffusers are easy, there are dozens of them on this channel. But I have not seen bass traps that mostly are mostly wood as far as you can see. Acoustic absorbers that look like wood are probably close to impossible. Maybe some very rough cut wood could be drilled out with a CNC machine and filled with foam on the back?

    • @pauljohn5584
      @pauljohn5584 4 года назад

      James Drissel Just watch a few more of Acoustic Fields' videos- they'll answer all your questions. Wood has MORE of an absorptive quality than drywall, but not necessarily enough to use as an absorber. Wood is used for diffusion in their meticulous designs and their proprietary foam is what they use for absorption. (As opposed to rock wool/Owens Corning or any other insulation material). I think this video was meant to point out the benefit of using plywood instead of drywall in a critical listening environment since drywall offers zero sound quality benefits. So if you're building a room from scratch, use plywood instead of drywall.

      using limp mass material types to reduce noise transmission will never work. You must first measure the enemy (noise) you are fighting. Once you know what the noise frequency and amplitudes are, you can then use the proper material types and construction methodology to minimize the noise transfer. Remember that with noise nothing is "proofed".

      They have the prebuilt acoustic panels that you can attach to wall or ceiling where there is an air gap. Or you can buy his build plans to make the frames to install the raw foam and then put your own fabric covering the foam.
      I personally recommend using a fabric over the foam.. It protects the foam, plus if you choose an attractive fabric, it's more esthetically pleasing than looking at raw foam. And you can play around with placing the foam frames up against the wall or leaving gap and see which one you prefer. You may like one method over the other..

    • @Oneness100
      @Oneness100 3 года назад

      it does for musical instruments. wood is a porous material and filling those holes with paint clog up those pores.. There are many types of paint, but more importantly, there are other things like primer, clear coat, and then there is how many layers do you have, are you wet sanding them down in between each layer, etc. Some paints are water based, some are oil based. There are additives like what the automotive paint companies have because they paint cars over different materials, so they need additives to allow paint to cover plastic parts or aluminum/steel/carbon fiber/wood, etc. As you can see, there are a lot of variables and what audible changes when used as an acoustic treatment all has to be tested depending on all the variables applied to the wood.
      I would say that depending on what paint, primer, clear coat, how many coats, etc. etc. may change the way wood sounds for acoustic treatment. You may or may not like the outcome from a visual or audible perspective.
