Question

As Zeta Anderson fires the engines of her stealth ship, the engines send vibrations through the hull of the ship (due to small misalignments. Still pretty stealthy, since sound doesn't travel through space). If the bridge of the ship is at 20 degrees Celsius, and the frequency of vibration is at 30 Hz, then what is the resultant wavelength of the sound? If the loudness corresponds to 10 phon, then approximately what does this correspond to in decibels?
