Traveling Waves: Comparing Pressures and Displacements

WAVES-1KVKAY

On a particular day, a $440\text{ Hz}$ sound wave with a maximum displacement amplitude of $1.6\ \mu\text{m}$ has an associated pressure amplitude of $0.30\text{ Pa}$.

What is the pressure amplitude of a $440\text{ Hz}$ sound wave produced in the same atmospheric conditions but with a displacement amplitude of $3.2\ \mu\text{m}$?
