no, smoothness of wood would be a factor for reflection.
wood does not 'absorb' sound.
only specially designed baffles, foam, traps, etc, 'absorb' sound.
only MASS reduces sound transmission thru an object.
a MASS of wood (say, 8" thickness) would start to 'STOP' sound, and even then, not as well as 8" of brick or concrete block, or even better, solid concrete panels.
