Ah yes, I remember now. Sorry. But still, I cannot accept that a solid slab of wood absorbs 80 to 90 percent around 1 KHz. There must be more going on than pure surface reflectivity. Those numbers are
way off from all the lab data I've seen. For example, the data I used in my Reflectivity article shows 6% absorption at 1 KHz for a parquet floor.
