I believe it's SSN instead of SNN in the diagramm. Submerging Ship Nuclear. I don't know how to change that. Michael, 2010-12-22

Michael is correct. The US sub designations should be SSN, not SNN. -- colinsweet, 2011-01-08 — Preceding unsigned comment added by Colinsweet (talk • contribs) 22:39, 8 January 2011 (UTC)

Axis

What is the point of a graph with no Y axis scaling? Is it linear or logarithmic? Mtpaley (talk) 19:09, 20 April 2012 (UTC)

Nonsense

I'm sorry but, what kind of idiocy is this? Even 688's sound levels are very well classified, let alone the Seawolf or Virginia classes. Amusingly, Yasen is launched this year -meaning even Russians doesnt exactly know its noise levels- so may I ask, how does this graph become a part of an encyclopedia? And yet, sound levels of a submarine is a function of depth and speed. Without both data, this graph is even more useless and full of laughable BS. — Preceding unsigned comment added by Andraxxus (talk • contribs) 13:00, 3 July 2012 (UTC)

I agree ... This graph would have been much more useful if the source would have been given. Yes, I know, there is a source ... but you cannot follow it to the data and explanations. On top of all this we miss the second half of the picture ... the sensitivity of the passiv sonar of these boats. On with both things combined could we judge who would have been detecting whom ... A diagram without a scale is an abomination. If you present real data then surely it's given with units :-(. JB --84.186.129.13 (talk) 20:51, 20 September 2016 (UTC)

Don't use a plain line graph

The graph implies that after a submarine class is introduced, it's noise level decreases linearly until the next class is introduced. This sounds silly, as the noise level stays the same, until the next class is introduced, doesn't it? Eranb (talk) 12:45, 15 August 2013 (UTC)
