    Hello Matthew, I find these types of videos the most interesting. Being an engineer though I like the numbers! The 10-15% absorption and 15-20% diffusion makes my ears prick up because I can work out the specifics for my space, even if as you said it’s just a starting point. So please, the rules of thumb are great to give an idea, but for those that like the maths, can you flash up the formulas where they exist? Please keep videos on room acoustics coming! Thank you.

    • @PoesAcoustics

      We could do a deeper dive.
      The 15% rule is really not a technical rule. It's more like a generlization that makes for an easy starting place. For what it's worth, Anthony and I both had this idea that we felt it didn't make sense to always do carpet on the floor. That a ring or U shaped solid floor perimiter would help keep some floor absorption while also reducing the amount of absorption on the floor (which isn't really desirable). We implemented, as standard, the U ring of solid floor in all our designs recently. The net effect is we are often now adding 18% or so of absorption to most of those rooms. And I tell that just to point out that these rules can't be tied back to formulas. it's more about how much absorption area most rooms tend to have and how much needs to be added to hit common targets as a ratio of total room area. But if you reduce fixed absorption area, like we did, then the ratio needs to change again.

    Matt, thanks for all the videos and for putting extra effort into production. Would love to see a video on the “shoebox side surround” scenario as I have a 13’ wide room with a pretty wide couch as the seating. Side surrounds at 90 degrees were too close even for a listener in the center of the couch, and due to a door I had to jump all the way back to 30 degrees behind MLP for my side surrounds.

    Really like the new video setup you have. Much easier to watch, more balanced.
    As to the content, a very nice overview. I would love to pick nits about side wall absorption a little. So many folks are placing their left and right speaker within inched of the side wall, and frankly, that places the first reflection point for almost all listeners right there on the wall next to the speaker.......and killing that immediate reflection really seems to clear up the sound stage, especially for speakers that don't have good directivity (ie, most of them on the market!).

    Great video as always! Since watching your videos I'm removed a lot of treatment from my over treated space. I've now got almost no absorption on the walls and just diffusion panels. In a room 5.5x4.5x2.2m I'm still struggling to get the RT60 about 200ms. It sounds great but I'm sure it could be better. The space behind my AT screen is heavily dampened with rockwool so I either need to turn this into a baffle wall or cover some parts with a harder surface perhaps.

    • @PoesAcoustics
      @PoesAcoustics  10 หลายเดือนก่อน

      That is a really common problem. It's one reason why I've become more careful with how I treat the front screen walls. In some rooms, treating the area behind the screen like you indicate can lead to a room whose RT time can't be sufficiently high.

      Yes a half cylinder diffuser actually works surprisingly well. While its not as technical of a product as a QRD type diffuser, the actual effect on scattering is massive and there is clear evidence of phase mixing, even if its not as good as a QRD. For such a simple device, they work so well.

      Yes of course REW works. That is a perfectly acceptable way of measuring it. It's not so much about the tool, nothing inaccurate about REW, its about how you do it. The correct way to measure the rooms RT time will be to place the microphone in a few locations around the listening area and take sweeps from both the left and right speaker (not together at the same time but seperately). This gives you the RT trend int he room over the listening area.

      Nearfield monitoring is a particular approach in which the monitor is placed so close to the mixer that you largely only hear nearfield content, no room. The direct to reflected ratio is extremly high. It's not an approach you should use in a home and it's not intended to sound better or real. It's a means of putting a microscope on the mix.

      The nearfield playback just causes very high direct sound to reflected sound ratios. So there are virtually no acoustic room cues. A lack of spaciousness and envelopment. Poor depth. Narrow apparent source width. Things like that. Which for what they are doing are all unimportant. They are listening for errors in the recording. The balance of instruments. Weird noises.

      Generally yes, but I might put a GUD diffuser toward the outside of the seating area. I haven't played with the GUD's that close much, but plan to try them. The developer has indicated that their nearfield to farfield transition is less than 12 inches, likely closer to 6". It's a really efficient diffuser and so it's only 2" deep (less really) but works well down to around 1khz. In theory such a product could be used behind your head. I would be interested to try it.

    First of all, your production quality is a million times better! Great job! :)
    For music listening, aren't most control rooms pretty dead? For me, the best listening experience is sitting in front of some really nice near-field studio monitors in a dead room. I want to hear the mix, not my room. Maybe as an audio engineer, I hear music differently than most people.
    However, for movies at home, I agree 100% that the room needs to breath. But, the few times I've been a post production stage, those rooms are pretty dead too. Maybe it works on post stages and movie theaters because there are so many surround speakers. Or are those rooms not really dead, but they just feel that way because I'm expecting such large rooms to sound like a cathedral?

      Do you mean is it important that every speaker is aimed at the MLP? Not necessarily. Very wide dispersion speakers often change so little over the listening window that aiming them doesn't gain a lot.
      I think a lot of people misunderstand why we aim the speakers. It's purely frequency response. If you aim the speakers correctly, you can minimize the HF errors between channels. If the speakers dispersion is wide, there are no meaningful errors. On the other hand, some speakers it matters. My speakers are not aimed, there is some variation channel to channel because of it, but its quite small, a dB or two at the highest frequencies.
      Aiming doesn't have any impact on things like immersiveness. It's going to be about how consisten the pans sound because of the change in timbre.

Would it be best to have the seating and surrounds in the widest part or would it's still very narrow width make any real difference? I know this would mean a smaller screen but would it sound better with that little extra space the side surrounds would be? The room was 2 roughly square rooms before taking the middle wall out. Ceiling is also only 8'. Thought 2 rows of 2 would be about the most possible there? Just worried about how narrow the room is and the placement of surrounds.

It sounds like a great idea. Anecdotely I've heard the room isn't very popular amongst artists/mixers and that its move to a multichannel mixing room stemmed from looking to revitalize the room and get it back in use. I don't know if there is any truth to that, or if they would ever admit it if it were true.
      What I can say is, nobody else has ever done that since. Which may be for good reason.

    • @PoesAcoustics
      @PoesAcoustics  10 หลายเดือนก่อน

      What do you mean by a movie demo?
      The object shouldn't be tightly pinned to the speaker itself. If you can tell that a panning object is coming from a specific speaker, I would call that a fail. It should be more subtle than that. Think about it, when an object is moving around you, like maybe a chirping bird, without seeing the bird, you can't tell exactly where it is coming from. The pinpoint location is related to visual cues. Hence why you have to look around a bit to find the bird. Movies should be no different. The issue is that in a room the direct to reflected sound tends to be a lot higher and reflections tend to be a lot more coherent than they would be in real life. So adding some diffused reflections helps a small theater approximate a larger real space a bit better.
      There are other issues too. A really dead rooms increases crosstalk problems, increases comb filtering audibility, etc. Basically, some reflections in a room are a good thing, they help reduce the audbility of natural flaws inherent in a multichannel system.

      We have a demo room that size coming together so i plan to use it as an exemplar of such spaces.

    I like movies with very good soundtracks as well as listening to music (The Rolling Stones, Pavorotti, etc. & Bohemian Rhapsody, Highlander, etc.)

    Room treatment is different for home theater and 2 ch. That kills a buttt ton of lame arguments! Thanks

      @PoesAcoustics You're on a great run here lately. I've been thinking about adopting Paul McGowan's approach and start doing Q&A style videos where I just answer one question per video in 5-10 minutes and just record a week's worth in one sitting and then post one a day.

      It's my last name and it's origins have nothing to do with the bad word in South African. It's from a Hebrew word in the bible that was translated in Russia to a different spelling (Poz) and then to Poes in America to make it sound more anglican. The fact that its also a bad word in South African is a bad coincidence.

      Yes and the way you pronounce it is also nothing like the South African word. However, what I found interesting is that TH-cam put your video up on my home page feed but your type of video is something I never really watch.

    How about the REALITY of building a FAR HIGHER QUALITY ROOM instead of simply making excuses for suboptimal performance that most make. I have ultra high end rooms constructed for both ultra high end 2ch and ultra high end theater both audio and video. Guesswork is amateur at best so getting it right requires those that understand and know far more than most of the players that claim to be experienced in the business. Another industry that should be regulated.

    Some of the 2 channel guys have bottomless pockets and no clue about acoustics. You are missing out on a lucrative market if your focus is only on hometheater.

    • @PoesAcoustics
      @PoesAcoustics  10 หลายเดือนก่อน +1

      I can work with 2 channel to. I just don't find they are as open to spending those bottomless pockets on acoustics. They will spend it on cables, tweaks, etc. Not rooms and cables. Which is too bad. I can make a 2 channel room much better. I can actually lower the noise floor many dB. I can improve spaciousness. All sorts of things that get attributed to tweaks, I can do in ways that are many magnitude of degrees greater than those tweaks.

    How does professional RT60 measurements with a dodecahedron loudspeaker compare to measurements with a regular speaker with a waveguide and narrow vertical dispersion? I would assume that with a regular speaker you’ll get much smaller RT60 values - is that correct? What’s your experience on this?

    • @PoesAcoustics
      @PoesAcoustics  10 หลายเดือนก่อน

      There were studies done in large rooms that found sizable differences. However studies were also done in small home theater sized rooms and found the oppossite, no meaningful differences. So it seems reasonable to use standard speakers. My recommendation is still to take multiple measurements with different speaker positions to create a composite.
