    Excellent video and use of ancient technology. I’m an audio engineer with 40 years experience in designing systems. The Helmholtz resonators were used in the grand gallery in the great pyramid of Egypt tuned to the resonant frequency of hydrogen. Chris Dunn, get his books they are fabulous, and some acoustic engineer friends of mine went there and did some extensive research on this subject. You could certainly target some of the major frequencies via phase cancellation. Using them to quiet generators is genius👍👍 thanks for sharing, nice work. Now about those calculations to determine the size and cavity dimensions of the resonators….

    This video is great. It’s the first one I’ve seen that provides a detailed technical analysis on noise reduction.
    I’d love to see the final assembly and know if there are plans or a materials list to build something similar. A follow-up video on its performance over the years would be fantastic. I believe you could generate a lot of content on this project alone.
    Also it looks like you used independent panels, and I’d like to see how they are fastened, how to disassemble them for maintenance, and the overall mechanical aspects of the assembly.
    All aside thanks a lot for the video and the rest of your content. 😁

    Your approach was great, measure the problem sound frequencies and suppress them accordingly.
    I'm going to work on one too but for a single cylinder diesel generator. It sounds like a distant helicopter and makes everything rattle. I was even thinking of using concrete too as it will be permanent for occasional battery charging in a residential area.

  • @RayleneCawood
    @RayleneCawood 9 หลายเดือนก่อน +1

    Mooi man! :)
    There is plenty of info on using a Helmholtz and/or a quarter wave resonator in the exhaust itself.
    You also see them on the intake systems of various motorcars.
    As this is a fixed rpm engine; I look forward to part 2 where we can hear yoiu breathing next to the genset.
    Another idea:
    A French Drain is basically a anaerobic 'digester' that produces methane that could be piped to the intake very easily with a thin tube to help with fuel. Perhaps add a tethered weather balloon for gas storage.
    Not a necessity yet but we all know sewerage will follow power into obscurity here, just as it has in rest of africa.

      If you’re handy you can extend the exhaust into a container of water to quiet down the exhaust. Same as most inboard boats. If you enclose the generator, have the water container in a “chimney of sorts” that vents to the outside. In the winter you should replace the water with RV antifreeze or even windshield washer fluid.

  • @sharkbite1686

    It looks like you only made panels on 3 sides for the resonators? Looks to me like the rear top is the 60hz, rear bottom is the 240hz, and at least one partial side is the 480hz (both sides?)? Are the front and tops just simple flat panels with damping? Really would have loved a slightly longer build montage showing more of the assembly.

    Awsome video! I'm ready to start building mine, but I would love to "cheat" off your design. I think I can figure out the number and size of holes to match my generator's acoustics but "reinventing the wheel" is never fun. So if you had some rough measurements to provide that would be fantastic!

      I'm sure you know this, but you really could make some money by selling the plans with referral links to everything you are using to do this project (from the sound measurement app, to the hardware, and everything in between). The plans don't even need to be that detailed. You have a lot of subscribers and this video is starting to get some traction in the DIY market in the US.

    Hi,
    what is the specification of the fan that you have been using?
    what its size?
    Is it pushing air out or pulling air in? [there are two types]
    What is the heat that it is build up in the chamber during hot wether?
    thanks for your response.

    • @SoundBlab
      @SoundBlab  ปีที่แล้ว +3

      The fan is 10inches or 250mm in diameter, and it pulls air out of the enclosure at 1100 cubic metres per hour. The generator does get hot inside, but so far I have not had any problems with overheating and the temp stays constant. The box is mostly in the shade though, this helps. I have run it between 2 and 4 hours at a time, and it is still going strong.

    You could probably make a business out of making these for various generators, because one of the biggest (ok THE biggest) argument raised against them is the noise problem. You could custom build them in parts and then ship them with assembly instructions.
    Great to see that doing a little homework (it's interesting that these have to be custom-built based on the specific frequencies you're trying to neutralize) paid off.

    I had to fire up my 11kw generator 3 times in the last couple weeks... about 20 hours each time.
    I was unable to get a nights rest when it was running, and neighbors as far as 5 homes away were put in that situation thanks to me having AC during a power outtage.
    I'm trying to come up with something to make it quiet.
    I was thinking about another neighbor who bought a generac that was set up in a cabinet. NOPE. Not quieter than mine at all.
    So I'm really really interested in a quiet cabinet, but so far, it's all short video with no real proof on how quiet they are, or short videos that don't actually give you a full build list and show the cost.
