ML - The conversation goes concerning noise of a submarine, instead of about her answer-back active echo.

Your mistake that you use the formula Ludger's which is more- less correct for surface ships (will not come yet cavitation - then noise all time not increased).
The formula uses LINEAR gain noise.

However - Submarine Gain noise, uses other formula - LOGARITHMIC!.

Your tables of comparison of noise of submarines - absolutely wrong.

Your tables are suitable only for the surface ships - from some share of a mistake (however on some speeds a share of a mistake makes 3 units(!) from current real noise).

The submarines generate absolutely other noise.
