Q. A whale at a distance of 2.0 nautical miles (3.7 km) and having an effective cross sectional area of 1257 m^2 is found by a transducer with a directivity index of 25 dB and radiates power of 3 kilowatts at a frequency of 30 kHz. The sound absorption coefficient for seawater at 30 kHz will be 0.0075 dB/m and there will be no masking by noise or reverberation, show how to determine the echo level. Assume there is a transmission anomaly of 10 dB.
