Office partitions as sound panels

Check my system updates. I recently added a few very inexpensive Auralex SonoLite 2 x 2 x 1 Inches Panels on my sidewalls that work as advertised. Just over $50 for 3 on sale on Amazon. They also sell wall mount bass trap panels and other isolation devices that I would readily try as well if needed.

Going from hard reflective to soft absorbent surface at prime wall reflection points is bound to have an effect on the sound, probably noticeable in most/many cases. Office partitions as well. Perhaps not to the same extent per square foot as other materials that are designed for the job. Could be a good or bad thing. As usual, it all depends...

KIjanki, by chance, I have similar bare insulation material from house construction covering the concrete wall behind my old OHM Ls in my basement unfinished area. Works to good effect there.

Those 1" Auralex panels are effective for high-frequencies and will have an audible consequence. However, much thicker panels are needed to extend the absorption into the midrange or lower. An excess of thin panels can make a room sound dead without doing anything to tame modes and resonances.

Mapman, I wonder if placing 2" panels on opposite walls works the same way as 4" panels on one wall? It should.

Kr4, I have a lot of reverberation between tall walls (cathedral ceiling). It would be ideal to space panels away from the back wall but I cannot do it being forced (by layout) to set my speakers and sofa on long walls. I can always control amount of reverberation by removing or adding panels.

Kr4,

Sounds right essentially. The product literature claims high and mid frequency effects. The bass trap panels they sell (currently showing huge discount on amazon) appear similar but 3" thick, which makes sense.

"Mapman, I wonder if placing 2" panels on opposite walls works the same way as 4" panels on one wall? It should."

I don't think so in that these are for controlling flutter echo and slap back, which are artifacts of more directional higher frequencies, as I understand it.

I have these placed at primary reflection points for my two main listening positions (my OHMs are omnidirectional and I listen from multiple locations normally). There are two such points on one side wall and 1 on the other (an open area extends out on that side in my L shaped room where I would add a similar second panel on that side if it were needed otherwise).

As I mentioned above, Aurelex has a similar 24X24X3 inch (same width and height, but thicker)bass trap panel product. Added thickness makes these more effective in attenuating longer wavelengths of low frequencies, as I understand it. These (for bass) might work equally well or maybe even better perhaps with greater thickness near one side corner rather than less on two side corners.
