If it were possible to generate a sinusoidal \( 300 \mathrm{~Hz} \) sound wave in air that has a displacement amplitude of \( 0.200 \mathrm{~mm} \). What would be the sound level of the wave? (Assume \( v=330 \mathrm{~m} / \mathrm{s} \) and \( \left.\rho_{\text {air }}=1.29 \mathrm{~kg} / \mathrm{m}^{3}\right) \)
