All what ive said is from the USN, when the lada amur class was built ths is where i quote from it was the second quietest submarine.
It obviously is not now (lada class started in 1997 and suspended) infact i too can think of many submarines that take ahead of lada.
Of corse the USN wont declassify submarine achostic data, but declassified information including the walker spy ring indicates that project 971 and its advancements are quieter than the 688i, even stated in janes and other defence reviews including norman friedman and norman polmar both international defence analysts working for the USN.
Russians long ago got over being excited about being as quiet as the 688i the SSN 21 only came to light in 1997 and now russia is playing catch up with the new generation submarines they are now trying to match virginia WHICH I MIGHT ADD THEY ARE ABOUT 7 YEARS BEHIND
Do you know how long it takes to find the sub classify it wash it threw your sonar computers you should , its not done in minuets.
The ambient noise of the sea masks many submarines achostic signature (if not all) making detection by broad band sonar near impossible that is why ew use Narrow band, and yes we can pick up submarines at 30 miles incredibly faint but you still can.
Scorpene, type 212, type 214, are all more modern submarines that the lada and all are quieter.
