A point \( A \) is located at a distance \( r=1.5 \mathrm{~m} \) from a point source of sound of frequency \( 600 \mathrm{~Hz} \). The power of the source is \( 0.8 \mathrm{~W} \). Speed of sound in air is \( 340 \mathrm{~m} / \mathrm{s} \) and density of air is \( 1.29 \mathrm{~kg} / \mathrm{m}^{3} \). Find at the point \( A \).
(a) the pressure oscillation amplitude \( (\Delta p)_{m} \)
P
(b) the displacement oscillation amplitude \( A \).
