Looks to me the Husky will try to achieve what Ohio class could. It was stated that Ohio class is the most silent boat, with noise level of some 90dB which is the same as sea noise background.

When India commisioned the last of the Kilo class in late 90's it was mentioned by them that these kilo is very quite with noise level equal to background noise of sea.
I think background noise of sea is a very vague statement

Ohio is ancient, there is no way their bar is that low.
Or it is.
If you read Tom Stefanick's book, "Strategic Anti-Submarine Warfare and Naval Strategy" You'll find this chart.
[ATTACH=CONFIG]260664[/ATTACH]
The way to read it is the top corner of the bar is the "high end" of the estimated noise level while the lower end is the "low bar" So the Ohio is about 90-110 dB. Any lower than Ohio is basically a diminishing return as the detection range of passive sonar in that region is basically same as the size of the submarine.
Why i took the book seriously ? Because it's sourced and the author have well scientific background and support. (Granted it's 1980 book but the science is still relevant today)

Boomers tend to be much more high-end than attack subs and may use solutions which just would be too expensive to execute in a series of fleet boat. Also their performance requirements are much less than attack subs.
When those French & Brit boomers collided, they apparently had no clue about each other prior to it.

In fact, they had no clue about each other after it, either - IIRC the two navies only pieced together what had happened after each had their sub report collision damage.
Russia's United Aircraft Corporation (UAC) has unveiled the Ilyushin Il-114MP maritime patrol aircraft (MPA) based on the Il-114-300 airlifter during KADEX 2018 defense exhibition in Kazakhstan.
The Il-114MP has a take-off weight of 26,000 kg and features six-strong crew, including two pilots and four operators. The aircraft patrols an area with a radius of 300 km at an altitude of up to 8,000 m during 12 hours. The MPA is powered by two Klimov TV7-117ST turboprop engines with a power output of 3,000 hp each. The Il-114MP has a practical flight range of 4,500 km. The aircraft requires 950 m to take off and 530 m to land.
The Il-114MP can be fitted with the Kasatka-S search-and-targeting system, which comprises an information management subsystem, a multipurpose radar with an active electronically scanned array, a radio sonar subsystem, a magnetometer, and an optical-electronic turret with a thermal imager, a TV channel, and a laser rangefinder. The system allows carrying of two Kh-35E anti-ship missiles and a GSh-23-2 23 mm automatic cannon. An Il-114MP MPA fitted with the Kasatka-S can detect a target at a distance of 120 km.
A source from the Russian defence industry said the Kasatka system had been intensively tested in various regions of Russia, including the Arctic.
At the MAKS 2015 international aerospace show, the Saint Petersburg-based Radar MMS company unveiled the Il-114LL (LL for ‘flying laboratory’) aircraft fitted with the Kasatka-S system. Radar MMS has developed several variants of the Kasatka for various air platforms, including light and medium utility helicopters (Kasatka-V and Kasatka-VB, respectively), medium and heavy MPAs (Kasatka-S and Kasatka-SB), unmanned aerial vehicles (Kasatka-BP), and aerostats (Kasatka-A).

When you dive to a certain dept, you will enter a Termic layer that will mask your sub. The decibel noise is slightly higher within this layer.
I suspect this is why they mention "merge with noise of Ocean" means.
When you get a Sub that is now below a value of sound decibel, it will mask itself within the Termic level of ocean.
But as always, there is the topic of distance between Sub and Anti-Sub surface ship.
"On July 26, a government commission chaired by Captain First Rank Viktor Ivanov signes an acceptance report on government testing of the frigate Navy Admiral of the Soviet Union Gorshkov, Project 22350," it said.
"On July 28, the ship will join the Russian Navy," the press release said.
Russia’s only aircraft carrier, the Admiral Kuznetsov, may be decommissioned if the Ministry of Defense and industry wouldn’t resolve the question of the replacing the PD-50 floating drydock needed to complete the repair of the ship hull, was reported by newspaper Izvestia, citing a source in the Russian Navy.
Russian Navy is considering prematurely decommission of its only aircraft carrier after then the PD-50 floating drydock that housed it sank.
In last year, a floating drydock holding the Admiral Kuznetsov sank following a power supply failure, causing one of the dock’s cranes to fall onto the carrier’s deck, leading to warship repair plant workers being injured. The incident left a 4×5-meter hole in the vessel’s flight deck.
Now the largest Russian Navy surface combatant ship is waiting for the decision of its fate near the wall of the 35th Repair Plant in Kola Bay near Murmansk.
Russia does not own a suitable replacement for PD-50 built-in 1980 in Sweden for the Soviet Navy.
Moreover, the project of the Russian aircraft carrier and before the tragedy caused a lot of controversies.
According to Popular Mechanics,over the last several decades, the Kuznetsov had already been beset by fires, budget cuts, and busted steam boilers. It’s so unreliable that a tugboat has been following it around on long voyages like a shadow.
Even before the PD-50 accident, a number of observers questioned the utility and expense of refurbishing the Kuznetsov. “In general, we need to critically review the domestic concept of the employment of carrier strike groups since Russia has undertaken to use the Admiral Kuznetsov to accomplish such missions,” Oleg Vladykin suggested in Nezavisimaya Gazeta.
Editor of the Moscow Defense Brief journal Mikhail Barabanov was dismissive of Kuznetsov’s upgrades. “Since Kuznetsov is not so much a combat platform as a training platform, deep modernization for her is an obvious excess.”
The Admiral Kuznetsov (heavy aircraft cruiser in Russian classification) was commissioned in 1990 and inherited by Russia upon the breakup of the USSR. The initial name of the ship was Riga; it was launched as Leonid Brezhnev, embarked on sea trials as Tbilisi, and finally named Admiral Flota Sovetskogo Soyuza Kuznetsov after Admiral of the fleet of the Soviet Union Nikolay Gerasimovich Kuznetsov.
In the immediate post–Cold War years, it rarely went to sea—conducting only six patrols between 1991 and 2015. In 2009, an electrical accident killed a crewman off the coast of Turkey. But Russia has repeatedly pushed the ship into service, and a 2016 mission off the coast of Syria saw the ship lose two jets in just three weeks.
At the moment, Russia does not have the technical and financial possibilities to restore its old aircraft carrier and also to build a series of new ones.
"A delay of three-four months is possible, but the warship will be handed to the Navy in 2021 as scheduled," he said. The aircraft carrier will dock at the 35th shipyard in Murmansk where dry docks will be upgraded.
The USC will also upgrade landing ships of Project 11711 according to Navy remarks. "We shall take into account all drawbacks exposed by the Navy in the construction of the next pair of landing ships," Rakhmanov said. They will have improved maneuverability, ergonomics and living conditions.
