Abstract :
Acoustic radiation in the water surrounding a ferry terminal pile driving project has been characterized based on 1/3-octave band filtering. The pressure field at approximately 10 meters is shown to be depth dependent based on data captured using a vertical line array. Decibel measurements of underwater sound are often expressed in reference to several non-interchangeable units, a summary of the differences of these references is presented.
