Determination of efficiency of anechoic or decoupling hull coatings using water tank acoustic measurements

, 2012
External anechoic and decoupling hull coatings are used on ships or submarines to reduce acoustic target strength and radiated noise, respectively. Measurement of test panels in a water tank gives only the reflection and transmission coefficients in free field, with respects to frequency.
