    Is there a video out there showing how to do the moving mic method?
    What about using MSO for multiple subs?

    I accidentally posted a question on an older video and wasn’t sure if you’d see it, so I’m reposting it here.
    I love the channel and truly appreciate the content!
    I have a sound isolation question for you. I’m planning to install an all-Perlisten 9.4.6 home theater (bed layer in-walls with an acoustically transparent screen) in my upstairs media room (21x13x9 feet, no windows). The room has partitioned back and left walls, while the front and right walls are exterior walls.
    I’m particularly concerned about the right exterior wall, which is just 12 feet from my neighbor's house (brick to brick). To mitigate sound transmission, I plan to install HushFrame all around and use an IsoDoor HD for isolation.
    My biggest fear is investing heavily and still disturbing my neighbor, preventing me from listening at or near reference level. Given the setup and planned sound isolation, do you think effective containment is achievable, or am I likely to run into issues? Additionally, will the choice between 10" and 15" subwoofers significantly impact sound transmission? Thank you!

    Great video, I've never tried the MMM method, usually take sine sweeps but will give this a try as I hadn't appreciated how many sine sweeps are needed to achieve the same level of data as a moving mic method.

    • @PoesAcoustics
      @PoesAcoustics  20 годин тому

      Give it a try. You should likely always do both. But doing both is not a big deal. You can do one or two sine sweeps and then a MMM and get much of what you need.
      Some people have this initial reaction that the MMM is inherently worse because it covers up all the problems. It looks smoothed. That is precisely the point though. All those single point in space errors cannot and should not be corrected. Seeing them isn’t useful, it’s harmful if you are driven to correct them. Measurments isn’t a game to see who can show the highest resolution, it’s about obtaining useful information on how to correct a system. The MMM provides some of the most useful information for Equing. And the Sine Sweep provided much do the rest. The temporal information.

      @ ohhh. Let me get back to you. So the primary way I do it is via a whole home surge suppressor and conditioner. That is what I have. But for local you need to be careful. Many of them will cause problems for the subwoofer and potentially degrade performance. We use Furman and equitech quite a bit.

      Yes this isn’t a novel idea. Professional front of house calibration has used multiple mics, commercial cinema has, and so has home audio. But I continue to see folks pushing single mic analysis and confirmation quite a bit.

    Actually you can have a situation where you have bass on one ear and no bass on the other. Really disturbing. I have this effect with my mains at like 90Hz. It shows up like a dip there in the measurement but is sounds really disturbing when this not is hit. I crossed my speakers at 120Hz because of this since my sub array is doing much better even up to 200Hz.

    I have to say I am very surprised of your reversal on the appropriateness of employing the moving mic method……you lit this poor guy up (in the comments section of the video) several years ago; I remember vividly you railing at him ua-cam.com/video/2i5QU8__mq4/v-deo.html&lc=UgxTGK2VPUnusQrXFLR4AaABAg&si=9S47ATu2bwrIizW6

      100% would love to see how to EQ a system using the moving mic method.

    • @PoesAcoustics
      @PoesAcoustics  20 годин тому

      Hah he convinced me.
      So to be clear. My concern at the time was a view in which sine sweeps are not used at all. I felt this was a huge mistake and still do. But what I came to learn after reading the AES paper on the MMM method was just how powerful of a tool it really is for obtaining spatial average information. So for equing a system it’s great.
      But it can’t be used instead of sine sweeps. And if your plan is to optimize bass using something like MSO, spatially averaged sine sweeps remain necessary. In addition, evaluating the effectiveness of the bass optimization would also require them as you need to calculate the mean deviation.
      But since this also has led people down a bad path of Eqing based on a single sine sweeps, I feel like it’s worth promoting MMM as a good quick way to obtain the spatial average you should use.
