Answer

The pressure amplitude increases by a multiple of $~~32$

Work Step by Step

In part (a), we found that the sound intensity increases by a multiple of 1000. We know that: $~~s_m^2 \propto I$ Thus $~~s_m \propto \sqrt{I}$ Then: $~~p_m \propto s_m \propto \sqrt{I}$ Note that $\sqrt{1000} = 32$ The pressure amplitude increases by a multiple of $~~32$.
