Wooden blinds vs cellular shades for acoustics


Standard old school advice for large window acoustical treatment seems to be "heavy draperies". Some cellular shades (Hunter Douglas, Bali) have high factory-rated NRC (0.60 or better). That's about the same for what little I've found for draperies.

Recently, I heard that partially-open wooden blinds are best for acoustics, acting through diffusion, rather than absorption. Opinions? Experiences?

Thanks

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 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
