Hmmm... new product... looks interesting...

http://www.baux.se/acoustic-wood-wool-products/ BAUX ACOUSTIC WOOD WOOL PRODUCTS Wood wool is a functional, natural material. BAUX Acoustic Wood Wool is made from two of the world’s oldest building materials, wood and cement. The combination is simple and ingenious. Wood fibre offers excellent insulation, heat retention and sound absorption. Cement, a proven and popular building material, is the binder that provides strength, moisture resistance and fire protection. Therefore, BAUX Acoustic products are versatile and durable in all climates. MAIN CHARACTERISTICS — Sound absorption — Thermal insulation — Fire resistant — Wet and dry rot resistant — Freeze-thaw resistant — Termite and vermin resistant BAUX Acoustic products meet contemporary expectations of architects and designers with a canny combination of form and function. They can be combined to create remarkable structural patterns that rejuvenate residential, industrial and public spaces. Designed by the renowned Swedish design studio, Form Us With Love, BAUX Acoustic Tiles and Panels are available in five colour sets and a range of beautiful patterns. Designers and architects can personalize any installation with endless creative possibilities. So... how useful does this stuff look?

Not very good at all for low frequency absorption, I'm afraid! Compare that with the specs for plain old OC-703: The highlighted line is ordinary unfaced 703, 4" thick. As you can see, it is many times better than this cellulose product you mentioned. It would have some uses, certainly: For example, of you needed something to specifically absorb the high mids without the lows or highs too much, then this would be a good product for that. But pretty useless for bass traps or wall cavity damping. - Stuart -
