    I added acoustic treatments to my room two years ago. Let me tell you it made a bigger difference than anything I have ever done. I think some people think they need to upgrade there equipment but focus on proper speaker placement subwoofer integration and acoustic treatments and I think you will be amazed about how good the equipment you already have sounds!

      Definitely 👌🏾 my small scale 5.1 home cinema isn't quite finished.
      But I've noticed a big difference in sound quality with the absorbers and diffusers I've already installed.
      Just waiting till April here in the UK to finish it off with a Sony A90J OLED tv. Can't wait 😁

      I totally agree! I learned this lesson the hard way and spent way too much money on AV gear before I went to treatment.

    Thanks for having an audio channel that has its feet fully planted in the new Millennium. Psychoacoustics and acoustics generally are so important. Bose made a living taking advantage of the fact that we hear with out brains. I'll take these discussions any day over Fremer's return to the '50s. I was there for that. It wasn't great.

    Back in the late 90's early 2000's I helped some friends of mine put together a low/no budget rehearsal/recording studio for their band. I had construction experience so it was up to me to build it. We had the building, a stand alone garage built back in the 1930's with 10' ceiling. After insulating the walls and hanging 5/8" drywall which is all the landlord was willing to pay for we needed to get creative with sound treatments. Not to far from the studio there was an industrial building that was being remodeled for new tenants and they where ripping out a grip of new T-bar ceiling acoustic tiles and 1/4" rubber backed carpet squares that the previous tenants had installed just before going bankrupt. They where throwing all of this stuff away so I helped myself to as much as I could. We used the carpet squares to cover the floor and glued the acoustic tiles to the walls two layers thick. Then we cut a bunch of the tiles into pieces that we stacked about 6 or 7 tiles high that formed a four sided pyramid that we glued together and attached to the ceiling in a checkerboard pattern.
    Next I found this carpet shop that installed carpet. The carpet as usual came in rolls that had at the center a thick cardboard tube that was discarded after the carpet was installed. This place was doing a lot of business so they had a lot of these cardboard tubes laying out by the trash cans so I helped myself to a bunch of them. We took these tubes and ripped them in half on my band saw so they where half rounds that we then attached to firing strips that we screwed to the walls every two feet. We would put 4 to 5 of these carpet tubes in a row and the a space. The ratio of tubes to spaces where always varied in size as to achieve what you where calling binaural dissimilarity, something I was aware of and practiced in setting up my own systems but ran into a lot of resistance from others when I would try and explain it. In the spaces between these carpet tube panels I hung strips of mass loaded vinyl that I found being thrown away at a manufacturing facility that used them as coverings over their doorways to keep the buildings refrigerated atmosphere from escaping out the open doorways while not inhibiting the forklifts going in and out of the building round the clock. I'm talking about clear plastic strips about 5" wide and in this case 9' long and about 1/4" thick and quite heavy. We weren't overly concerned about aesthetics but things didn't look to bad and the acoustics in this room ended up sounding as good as any professional studio. So in the end we where able to sound treat this room for the cost of some tubes of adhesive and a few boxes of screws and the time it took to do it. Granted we where lucky to find the things we did when we did.

  • @wells2671
    @wells2671 3 года назад +6

    Maybe I missed this part in the presentation, but how do we use something like REW to actually measure the room and see whether or not we need these treatments? I've seen videos about the mirror trick for reflection points etc , but ultimately to the untrained ear, how can we use software to tell us or show us what we may not recognise as a problem? We have to realize that if the room sounded good to us before (because we couldn't tell the difference), than we would need something else to show us these problems. Maybe someone like Anthony could walk in and hear the problems right away, but the average homeowner may not recognise these things as problems. It would be good to have an explanation of how we can use tools like REW (or whatever else) to actually assess the room and then figure out IF and where we need treaments.

    @Finite-Tuning 3 года назад +1

    Alright, ya guys finally broke me! After trying to re-tune my system I found some problems I just could not fix. It's gotta be the room causing this, I know I have an echo so I finally broke down and ordered some bass traps for the corners and some thick acoustic panels for the walls and ceiling. Just for quick and dirty testing I hung up some thick bed blankets on the walls and sure enough, big difference! So I felt confident spending more than a few bucks on some actual panels that will look a whole lot nicer then some bed sheets lol.
    Cheers 🍻.

    Best video and what I've been telling friends for a few years now. Speaker room integration/interaction is key. Cables, equipment, and amps are truly the least concern although amp and speakers should be a good match due to dynamic impedance swings and speaker efficiency differences.

    I'd like to hear about both topics (bass absorption and diffusion). But I am more interested in diffusers. Different types of diffusion, use cases for the different types and figuring out what types to use.
    Either way great stuff! Looking forward to hear more!

    Guys, I have to say you've spoiled it for me, and I mean it in both a good way and a bad way :) A great video indeed, a wealth of knowledge - thank you.
    I always knew room treatment is important for best sound, but I didn't know how important. Now I know that no speaker will sound great in my small (20 m sq. / 215 ft sq.) room, and indeed they don't sound great, even though I used to think they do! I wanted to DIY a really good set of speakers, but now I doubt there's any point.

  • @tonesbones502
    @tonesbones502 2 года назад

    Great video guys. It's funny, when I have gone out and auditioned equipment I have noticed the hifi stores often over do the absorption and the listening room sounds dead. The music sounds odd and I must say the music in my room at home sounds much better. They have millions of dollars of high end equipment in there and don't realise they are making the gear sound average. Its a wonder they sell anything. From what I've gathered here there is a formula and reflection is the key.

    Thank you for this precious sharing! Technical enough to grasp concepts. A question for you, since the listening room and his environment are so important, why so many shops, also with hi-fi recognized products, doesn’t put them in a good, prepared room, instead of a simple shelf inside the shop, the maximum correctors are a thin carpet and an harmchair?

    Very interesting presentation.
    What about combining esthetics and sound absorption/deflection:dampening the old fashion way by placing on and along walls different size pictures and furniture like wall cabinets, and experiment by mowing them around until the sweet spot is located?
    Newest AVR are equipped with the software that “adjusts the sound according to the listening room and speakers therefore creating clearer sound by suppressing the standing waves that occur between walls or ceiling and floor.”

    Well my room is 17' wide, 23' long (left side) 14' long (right side) and has 13' vaulted ceilings. I am using identical tower speakers (Infinity P363) on all channels and am making sure that they are all far enough away for proper driver integration. I'll be able to do 5.1 + wides so 7.1 total. I will treat as described here and do speaker layout and calibration as described here. It will be a dedicated room even though the room is somewhat open to the kitchen. Hopefully the big speakers aren't a problem in a 3200 cubic foot room. Only one way to know.

    @juhapeltola8232 11 месяцев назад

    You must have symmetry to have proper center image. And your example picture the front wall is completely empy. That is the most important wall to treat. Small rooms I don't even bother diffusion. To know how sound works it is very easy. If you have symmetrical room and speaker setup it is very important to treat the room the same way. Another center speaker is just that what you want. Proper locked center image.

A portion of the ceiling is slanted and the dimensions are not that impressive: 4,47m length - 3m width, 2m height (1.60m until the ceiling starts to slant ). I have placed my mixing desk on the long wall, because it's the only one bare and because on the right side wall is a window. Could you, guys, give some tips for treating this kind of room?

Local auditorium is a serious theater routinely overblasted by volume settings to please the artists on stage BUT destroying sound, giving echoes, distortion, thumps against the chest with volume. Good system controlled by chimps.
