REW Measurement after first treatment with Caruso Iso Bond wlg 035
Hi,
i began to treat my room and I decided to buy a first pack of 6 Caruso Iso Bond Wlg 035 (1200 x 600 x 50 mm).
Flow Resistivity: 10,000 Pa⋅s/m²
Density: 40 kg/m³
I chose them as they are safe to breathe and specifically I chose the 035 because they are available at Thomann (this shop doesn't have the 040 or 045).
I tried different combinations and I decided to measure how they worked as bass traps in the corners of the front wall (3 panels for each corner. In total a thickness of 15 cm for each corner).
- In the first picture you can see the result:
- The red line represents no treatment in the corners
- The blue line represents the treatment as I described
I believe the discrepances below 50 hz are due to noise floor.
2-3) You can also see the Waterfall graphs for the low frequencies. The first one with treatment and the second one without.
I don't know if the Caruso panels are doing very little or if it is ok.
- Then I also made another measurement (in the room with no bass traps in the corner), moving the mic back 30 cm more or less, to understand what is due to standing waves and what to SBIR.
The green line in the last picture represents the measurement with the mic back 30 cm.
What do you think about all of this ?
