A sealed tube of length L = 1.34 m is filled with a liquid of
density p = 1.20 x 10^3 kg/m3 and bulk modulus B = 2.18 x 10^9
Pa. When the tube of liquid resonates at its fundamental frequency,
it acts as a source of sound waves of power P = 3.00 W. How loud,
in decibels, is this sound at a point where the sound waves have
traveled 8 wavelengths through the air? The speed of sound in air
is v = 344 m/s.
