Detailed Solution

A soft board will absorb most of the sound falling on it.
It is so because soft materials have pores. These pores absorb the sound energy falling on it. When the sound waves pass the material it will lose some energy in the process. As any soft material having pores act as good insulators, they absorb most of the sound.
