It has been suggested that US military tests of a powerful form of sonar (SURTASS-LFA) was responsible for the deaths of quite a few whales some years ago. This device produces under water sound waves with a logarithmic intensity (loudness) of ~235 dB as measured at 1 m from the source. If they turned down the intensity so that the new loudness is 180 dB, what would be the amplitude of the pressure wave at 1000 m from the source?
