pask74, 10 May 2014Hi there! After a 2-year acoustic break, here I am again building a new control room. With this one, I'm trying to practice the basics that I've learnt here, which I…
pask74, 10 May 2014Then, reading on this forum that a solid concrete floor is a good starting point, I had a concrete floor made by professionals. So, first step was to remove the carpet…
stevev, 11 May 2014ouch is right. that's going to be a tough room to get under control. I had a look at your sketchup plans and they don't appear to show enough details to comment on the…
pask74, 13 May 2014Yes - I actually haven't done all the things I recommend on doing ;-) In this case, SketchUp-ing the whole thing. With this project, I have quite a few constraints,…
pask74, 13 May 2014Front right basstrap: - structure: Image not preserved: btr - wood.JPG - rockwool: Image not preserved: btr - iso.JPG - cloth: Image not preserved: btr - cloth.JPG It's…
pask74, 15 May 2014OK - so I've tried again to attach an .mdat file without success and its zip version weights too much, so here are jpegs. Image not preserved: vocal academy may 15 12h -…
pask74, 15 May 2014I just made 2 measurements: One without the plastic sheet on the front left basstrap One with it. It seems that the 3k-9k range is slightly affected by this change (RT…
Soundman2020, 16 May 2014Yep, that link works fine. However, the data in your MDAT file is suspect. According to that, you did the test at a level of about 140 dB :!: :shock: If that were, true,…
pask74, 16 May 2014Hi Stuart, thanks for your reply. Here is this morning's measurements: https://drive.google.com/file/d/0B6wx2y ... sp=sharing Test level: it was a bit too loud (the…
pask74, 16 May 2014OK, so I wanted to understand more what this plastic layer is doing to the sound, so I removed the upper half of it on the left wall. Here are the results:…
Soundman2020, 16 May 2014Did you follow the complete calibration procedure? You have to tell REW what the real level is in the room by measuring it with a good quality hand-held sound level…
pask74, 16 May 2014Hi Stuart, Mic: Behringer measurement microphone (the famous one lots of people seem to use). It's located at 38% of the length of the room from the front wall. Speaker:…

Soundman2020, 18 May 2014Well, maybe "dead" is a bit of an exaggeration, but you'd most certainly be deaf, and also in pretty heavy pain! You need more like 200 dB to actually kill you…
pask74, 18 May 2014I try to avoid exposing myself to more than 92dB-ish. Those h u u u u u u u u u ge speakers are just, well, American-looking to me ;-) Room's size: - depth 455 cm (but…
Soundman2020, 19 May 2014:wink: Yup! They are actually used by the USA armed forces to simulate the sounds of a battlefield, for training purposes.... :shock: :!: That's actually not a very good…
Soundman2020, 19 May 2014I'm sure you are hearing something ! No doubt about that. What I'm not sure about, is that the REW data is showing what you are hearing, since it doesn't make sense.…
pask74, 19 May 2014Stuart, I like your style ;-) Thanks for your follow-up. Ratios: message received, cap'tain ;-) I'll look into those BBC critical tests as this sounds very interesting.…
pask74, 19 May 2014Hi there, So, I used the calibration noise (white or whatever) and made sure that the level was about 80-81dB. Then I made a measurement (link below) but it still…
Soundman2020, 19 May 2014Did you actually tell REW that the level was 80 dB? I mean, you saw that you were getting 80 dB on your hand-held meter, and that's great, but then you also have to…
Soundman2020, 19 May 2014:) You aren't the first one to notice that! And I'm sure you won't be the last either... It is documented in the REW manual, but you have to go digging to find it. I…
pask74, 20 May 2014Hi there, So, I'm back to my initial impressions after measuring again this morning. In this file, you get 4 measurements: 1. upper left wall without plastic (only…
pask74, 20 May 2014... and some pictures: Measurement setup (microphone is placed at 38% of the front wall's width, 1m20 from the ground) Image not preserved: hp - mic.jpeg Left wall…
pask74, 20 May 2014I am in the middle of removing the plastic layer from the back and the side walls... a bit gut-wrentching as it took me quite a bit of time to install. Anyways... I…
Soundman2020, 20 May 2014:shock: :!: Whoa! Hang on there! I'm not sure why you are doing that, since you are still a LONG way from completing the treatment of the room! Treatment is a complete…
Soundman2020, 21 May 2014OK, I had some time to look at your data. Well, you have data smoothing set to 1/3 octave, so you are probably missing about 90% of the useful information in the REW…
pask74, 21 May 2014How do you know that I understand food analogies very well ;-) ? Thanks for this input. I know it sounds silly, but this room needs to be at least usable for vocal…
pask74, 21 May 2014Thanks for the tips! (That sticky note would definitely be very useful). Is there any recommendation about the distance the microphone should be from the floor (or…
pask74, 21 May 2014OK - will do. I can remember reading posts from members who sounded pretty skilled here saying that they usually use a fair amount of smoothing on these EQ curves, but…
pask74, 21 May 2014Measurement test setup: I've tested the cables (!) but the curve I get is the same as the converters/preamp one, so no worries on that end, apparently. I also simply…

Soundman2020, 22 May 2014Interesting new data! Something changed... the high frequency boost is mostly gone, which makes me think that maybe you had the measurement mic too close to the tweeter,…
pask74, 22 May 2014Very, very useful Stuart - thanks a ton! Use of the room: it will primarily be used for vocal classes but also acommodate a writing/composing/producing setup. Tracking…
pask74, 22 May 2014File not preserved: Plan Vocal Academy - 2014 05 22.skp OK - I've just Sketchupped 2 ideas to add basstrapping to the room. What about a large back wall corner trap + a…
pask74, 31 May 2014OK, even though I am under the impression that I'm talking to myself here ;-) , here are some news. The room needs to be at least usable on... Monday! But we'll have to…
Soundman2020, 14 June 2014The readings get less accurate at lower frequencies, but they are still plenty good enough to show what your room / sound system is doing. They won't be accurate enough…
pask74, 14 June 2014Hi Stuart and thanks for your feedback! I was starting to feel alone, as you're apparently the only one able to answer all the questions so many people have the forum…
Soundman2020, 14 June 2014:| Yeah, it sort of seems to be that way! I sure wish more folks would join in with responses, especially those that have already finished their rooms, or seen major…
pask74, 17 June 2014No problem - it now sounds like common sense but I had cables running in and out of the room, thus the open door and window. Should this treatment mostly be rockwool or…
pask74, 19 June 2014According to what we've discussed for the back wall, I've created a pretty large 88x240x17cm panel. It has 10cm of Typ3 rockwool and 7cm of air gap. I put plastic on…
