New Studio Space - Bass Trapping (PING! Ethan W. & anyone else interested)
Hey gang, some of you may find this interesting, since it's a somewhat
different kinda space. So I moved into this new place, partially because it would afford me the space to enable me to expand my little studio operations into somewhat more than a simple MIDI/overdubbing studio. I'm getting things configured, and as I'm doing so, I've noticed what I think is an extremely annoying room mode problem... as I'm listening back to the first few things I play over the system, I get this annoying "woom-woom" thing happening (and no, I don't mean "womb-womb", like Mixerman would want it lol). First thing I do is say: "****... 200hz.", then I listen some more & I'm thinking maybe not just that, but somewhere up into the 300-ish range, too, but now I'm second-guessing myself & I'm not sure. So, I downloaded Ethan Winer's room mode calculator & plugged in some figures - yep, with the room dimensions that I've got, there's definitely some problems in the 208-237hz range (if I read it right), but there's another issue... I'm not sure which calculations to use, and if you click on this link, you'll see pictures that'll explain why: http://www.saqqararecords.com/html/newstudio.htm At the listening postion, the effective "width" of the room is 67 feet, if I were to move back just a little bit, it would be 19 feet. Is the 19-foot width impacting much of my listening experience, even though I'm not directly "in the zone" of that width? Or not? Personally, I think it's mostly a floor-to-ceiling mode problem... that's the shortest measurement that produces anything in the 200-ish Hz range, and as the shortest measurement, would contain the most energy in the problem range, right? There are a couple of frequencies below that that may be a problem, like to 67-75Hz range, and using the 67 feet measurement, there's a doubling at exactly 59 Hz, but I'm using fairly small speakers & not blasting them all to hell, anyway; so I wouldn't think that they're putting out a lot of power down that low - not enough to make it a serious issue, anyway... right? Besides, those frequencies don't go "woom-woom" lol So what do you guys think, and where & how should I trap this dump? On the ceiling first & see what happens? Input appreciated. -- Neil Henderson Saqqara Records http://www.saqqararecords.com |

67 feet wide!?!?!?! Man, I just spent the weekend trying to fit all
my crap into a control room 8.5 feet wide. wrote in message . .. Hey gang, some of you may find this interesting, since it's a somewhat different kinda space.

The imaging's pretty incredible,though :-) (Good luck with the glassed-in drum booth :-) It's only glassed-in on one side... some heavy curtains might do the trick - we'll see. -- Neil Henderson Saqqara Records http://www.saqqararecords.com |

om... 67 feet wide!?!?!?! Man, I just spent the weekend trying to fit all my crap into a control room 8.5 feet wide. Well, don't forget, I said that was the "effective" width, for purposes of calculating that mode at the listening position... the actual room itself is not that big. But I can sympathize with our plight, I've been in small CR's before. -- Neil Henderson Saqqara Records http://www.saqqararecords.com |

Hi Neil,
Is the 19-foot width impacting much of my listening experience, even though I'm not directly "in the zone" of that width? It could be a factor. Basically, any pair of large, parallel surfaces can contribute modal resonance. I think it's mostly a floor-to-ceiling mode problem. That might be a contributor, but I'm guessing it's just too much ringing and low frequency reverb generally. The exciting frequencies in the music you're playing are obviously the biggest factor. This is why the only real way to know what you have is to measure. where & how should I trap this dump? On the ceiling first & see what happens? The best place for bass traps is in the room corners, and that includes the ceiling corners. The problem with a very large space is you need a very large number of bass traps. I'm not usually one to recommend making a room smaller, but in this case you have the perfect opportunity to build walls that make the room a more optimum size and shape. If building a few walls is feasible, and you can wait another week or two, the September issue of EQ magazine will present plans for a complete project studio with ideal dimensions. --Ethan |
