Sub-bass control with resonance traps. The holy grail of studio acoustics.
When it comes down to it, the lowest of the lowest audio frequencies can really only be properly absorbed with targeted, tuned resonance absorbers.
For most of us DIY audio engineers, this tends to be outside the scope of what we can do.
The price-performance ratio of resonance absorption is… average. To put it mildly.
And it’s not usually necessary either! You can do WAY more with standard porous material than most people think.
But if you really want to go all out with bass control into the lowest frequencies, resonance absorbers (and membrane absorbers in particular) are your only option.
And that’s what I want to show you in this week’s video.
Jesco from AcousticsInsider and I are wrapping up the treatment of our new demo room by installing membrane traps.
As before, we’ll walk you through the exact process of placing them correctly and of course: before and after measurements.
You don’t want to miss this one.

    Very interesting discussion. Square rooms are just no fun for acoustic balance. People always complain how they've spent thousands on absorption, yet hear little improvement. I always recommend large false wall panels 4" from the real wall to essentially "reframe" the geometry of the room, addressing the room modes and and standing waves. This also secures a healthy air gap built into the room.

    I've got a question that I've wondered for such a long time with this video and with Jesco in particular... From 80hz down, why do studios that fall under the small-room-acoustics umbrella not employ a multi-sub approach to flatten the FR of the bass and then use treatment to take care of the decay time? For that matter, if you have your subs mounted directly under your monitors, you could even extend the multi-sub benefit higher to 120hz-150hz... maybe even higher? I've got zero treatment in my 18x19x7ft room and can shape the FR of my subs to whatever I want it to be with my multi-sub (only 2) approach and Dirac Live. This was after optimizing my seating placement and sub placement.

    @ Music City coustics: You are showing everyone that you really know nothing about acoustics. But as Alice in Wonderland asked the Cheshire Cat, “Would you tell me, please, which way I ought to go from here?” “That depends a good deal on where you want to get to”, said the Cat. “I don’t much care where-” said Alice. “Then it doesn’t matter which way you go,” said the Cat. If you don’t know where you are going, it is highly probable that you will never get there.

    • @davidschlender587
      @davidschlender587 3 місяці тому

      You can't calibrate a microphone without a reference source. That's what calibration means. You need a calibration file or another microphone that has one. Or you could send your microphone to a lab and they can do it for you.

    • @MusicCityAcoustics
      @MusicCityAcoustics 3 місяці тому

      Great question! Unfortunately, I'm not sure REW can generate a cal file for your microphone. However, for most room measurements, having a cal file is not super necessary, so don't let it hold you back!

    • @slofty
      @slofty 2 місяці тому

      Audio engineer here. We don’t bother with cal files because they don’t really make a difference. You are more likely to end up with issues from using one in the first place do to reference or generative errors by whoever did the calibration than just using the device stock as they are good enough to begin with. Just use it out of the box and it’ll be fine. The only places that need absolute accuracy are high-dollar sound production facilities and their mics are $$$$.

      GIK makes custom tuned bass traps by request.... If you contact them with details of your room including measurements, they will be able to tell you exactly how many of those custom tuned traps you'd have to buy and according to Harmon's Room Mode Calculator, they'd be evenly distributed throughout the room placed on-wall at 2ft and 6ft measured from the floor. The traps aren't cheap but they work exactly as marketed on their website.

And R as loopback input and R as timing reference... is that correct? Also would i need to connect a TRS from the 2nd channel of my interface which is an XLR/line (aka R input according to ReW) and feed the the other end of the TRS to the Right monitor out or is the Right line out sufficient?
