Wooden blinds vs cellular shades for acoustics

Well....assuming most rooms will have 1 wall of large window coverings unless you bought a church like Arlo,that is indeed an interesting question.Being it is part of 3 other walls[usually] it will be next to impossible to comment adroitly.Soundwaves like diffusion and absorbtion to varying degrees depending on the total area with whats there.For instance I have a wall of windows,8'x20' covered by shades which I move up and down according to the Sun.I have not found a difference yet as to there height though I havent been listening/looking for one.If I do I will remember this post perhaps and thank you for opening my ears,cheers,Bob

I have three windows on the left side of my room that measure approx 34x60 ea so in effect the windows dominate that wall. I previously had cloth vertical blinds and recently replaced these with solid wood shutters.
Sonically, I feel it is an improvement compared to the verticals. It is also possible to make some adjustments to the presentation by different orientations of the wood slats. It is not a major change, subtle but noticeable. I don't know how the shutters would compare to standard drapes or other types of blinds. I feel I made the right choice. I will post updated room photos in a couple of weeks once new carpet is installed.

I was where you are going to be in regards to your carpet.When that goes in all else will be majorly overshadowed.In my place it was a good thing as I am in a condo.If I had my own place I would go with wood floors,YMMV,Bob

I have wood blinds behind my speakers, never experimented with partial opening, unbelievable! Will have to try this weekend.

Closed, they are reflective, it will be interesting to note the amount of added diffusion when partially opened, something I've been looking for. It does seem that the diffusion properties would be somewhat limited by the window behind being in such close proximity to the wood blind. In the summer the storm window can be pulled out, I suspect the added space behind would increase the diffusive properties. I also have cellular shades on one side wall, these absorb sound, however, not to the extent of my Echobusters.
