Soundman2020 - Studio Design Forum

Hello,
I am sending the last final measurement, you can look at it and evaluate what parameters my room has, or what could be improved. I originally considered adding barrel diffusors to the back wall, do you think it could improve the parameters?
Thank you.

Hi,
I send measurements with and without a table. The table seems to have better results, although the differences between the right and left monitors remain. The same position of listening to the monitors, level about 75 dB.

Thank you Soundman for analyzing the measurement and explaining the problems. It's an amateur studio, I don't need professional parameters. The room has its limitations, it will be used only for home recording, mixing. In the untreated back part of the room (behind the chimney) I wanted to install p...

A chimney measuring 1.2 m x 0.55 m passes asymmetrically through the room, see the drawing with dimensions. It probably causes differences in the symmetry of the reflections of the left and right channels. On the chimney there is an absorption panel hr. 50 mm slight wave see photo. I'm sending a few...

I also have an untreated room measurement, but I didn't want to put data from the untreated room on the forum, these are the screenshots posted above. I tested the SBIR distance of the speakers from the front sloping wall 0.5 - 1.4 m. I haven't treated the back wall yet, there are only bass traps. A...

Hello, I am sending the m.dat file from the measurement after the basic treatment, bass traps, cloud, 10 pieces of panels on the side walls made of mineral wool 5 cm. The best SBIR is when the speakers are placed as close as possible to the front sloping wall. Mic Behringer ECM8000 (embedded calibra...

I don't want to analyze yet, the room has an echo. When I have the basic treatment I will send .mdat. I test how low frequencies behave, I move the speakers and the listening position. I have a fairly large table, I compared measurements with a table and without a table. I'm sending a few photos for...

18-260 Hz

Hi, so finally finished, we will publish the photos next week. I did preliminary REW measurements without any treatment (waiting for the delivery of mineral wool) with a Behringer ECM8000 mic (approx. 70 °) 2.5 m from the front wall. Speakers 1.3 m from the side walls and 0.5 (almost in contact with...

Thank you Endora for the information, everything you write makes sense, I followed the manufacturer's recommendations too much.
The distance of 1.5 m is probably not optimal.

Which frequencies are more and less harmful?

Endorka studio is not finished in the reconstruction yet. I can only simulate in software. I moved the monitors 20 cm to the front wall, in PDF comparison. This position is better, 63 Hz improvement; 125 Hz, deterioration 160 Hz, improvement 400 Hz; 500 Hz; 1kHz; 2 kHz; 2.5 kHz; 3.15 kHz. Garethmetc...

If I moved the speakers away from the front wall, I would get close to the center of the room with the listening position (green diagonal lines on the original floor plan - low bass). This condition may not apply if there is an obstacle chimney.

Thank you for the information. Do you know software Olive Tree Lab Suite? I tried to simulate in software comparing 4 room types. Classic room, classic room with chimney (obstacle), attic room (sloping walls), attic room (sloping walls + obstacle chimney). Range from 25 Hz to 10 kHz. Exactly as endo...

Thank you endorka and Starlight for valuable information, I follow your great projects. Monitors should not be on an axis 45 ° from the corner. My monitors are located on this axis, which is not good, they should be from the inside or outside of this axis. I think that's why SBIR is doing so badly. ...
