I've recently treated my studio with corner bass traps and broadband absorbers.
I took some measurements with REW before and after the treatement. I'm also in the process of tilting my speakers slightly up with the isoacoustics and putting them in the same place for some more measurements.
I'm wondering if you could have a go at my REW files and see what you think ? After reading some forums and trying to get my head around REW I must admit that I'm really amazed at the difference the treatment did. Specially if we talk about how I had absolutely no bass frequencies at the listening position and now I can listen everything.
However, I recon I'm still facing some problems and I'm wondering what's the dimension of them ? I don't know if it's worth to tackle them as the response, to my ears, seems really adequate to the type of compositions I will be doing in the studio.
Should I post a download link to my REW files or simply post the SPL/Waterfall graphics with some specific parameters ?
I didn't know this forum existed and just wanna thank you for the time you put to answer everyone's questions.
Hey Kraft, how are you? My name is Michael and I'm an acoustics amateur. I'd like to see your graphs. I used the capture function in REQ Wizard and was sure to label them in the popup dialog.
Some parameters you might want to follow is to give at least three or four graphs per measurement: 0-20kHz no smoothing, 0-300Hz no smoothing, 0-20kHz 1/3 octave smoothing, and a waterfall graph with 5dB margins above and below a 30dB range.
You need to host your images on an external site such as 'Photobucket' then add links as provided by them to the thread under the 'image' in the reply tool. This is found in the full reply to thread - not the quick reply..
You should be able to add attachments directly to your post, but there's a size limit of 1 MB per file. So don't try to post a 5 MB BMP file! Also, it's best (for the forum) to limit graphs to less than 100 KB. A GIF file plenty large enough to read can easily be as small as 20 KB or even smaller.
Without knowing the size of your room, and how many bass traps you have, and how big and thick they are, it's difficult to comment on your response graphs and how to make things better. Maybe you can also post a photo or two?
I have soffit style traps in all corners (4), floor to ceiling (almost).
Above the listening position are 2x 8'' panels. On the first reflection points there are also 2x 8'' panels. Further behind there's one more panel on each side with the same specs but with some reflective foil on the front. On the backwall there's a huge moving panel that blocks the entrance to the room - I place this panel in it's position once I enter. There's also another 8'' panel on the back, between the corners.
There are 4'' panels on each side of the room where the ceiling meets the wall, they are straddled.
All the panels are made of rockwool with 55 density and mostly 1,40 meters X 70 cm. There's a small gap between them and wall and some of them have a bigger gap. I couldn't make bigger gap on all of them due to the space.
I was posting the graphs to get an idea of what I've accomplished. There's no going back now, I can only keep making more traps whenever I have the time and add them to the empty spaces.
