It has been suggested that the US military tests of a powerful form of sonar (SURTASS-LFA) were responsible for the deahts of quite a few whales some years ago. This device produces under water sound waves with a logarithmic intensity (loudness) of about 235 dB as measured at 1 m from the source. If they turned down the intensity so that the new loudness is 180 dB at 1 m, what would be the amplitude of the pressure wave at 1000 m from the source?
a) 3.0 X 103 Pa
b) 2.2 X 103 Pa
c) 1.7 X 103 Pa
d) 7.5 X 103 Pa
e) 8.2 X 103 Pa
