The sound absorbing plate is the auxiliary and the diffuser plate is the main one. Sound absorption is to absorb echoes. For example, in an empty house, if you feed it, there will be a long echo. Say a word, all echo, can't hear clearly. At this time, except direct sound and a reflected sound, all the other echoes (tails) should be absorbed, and the sound should be attenuated as soon as possible.

The sound absorbing board handles the tail of these sounds.
