If these measurements were being taken by a Russian trawler off of Norfolk as a US sub left, I know that from what I have read the US subs will make all the noise they can while departing so that they are masking there "True" sound signature. So it is possible this may not be an accurate reading of the real capability of a 688. We would have to know in which context the readings were taken.

Sorry, but my english not good
So as I understand you.
Yes, US submarine have masking device during work noise instead submarine heard like surface cargo ship. But from 1985 year for submarine northern fleet find us submarine in range from 300 to 1000 cabl. For example place between Grennland and Nord Cap monitoring 2 submarine only. As I heard, 1 submarine near Bear islad can find US submarine near British islands. As I remember in 1987 year.
In 1986 year during operation in Atlantic average range detecting us submarines was near 400 cabl.
In few days ago when our 2 submarines fire SLBM from Arctic not 1 US submarine can not find our strategic submarines before launching as you know
So you can see real situation when 2 russian SSBN can stealth patrol in starting position. All us submarine was detecting our submarines and can not made himself work.
All data range from Northern fleet.
Another - sorry with my english.
