Any ideas on if a muzzle break that's padded with heavy felt either on the inside or outside would aid in sound suppression on a .22 magnum springer?
Muzzle brake for supression

IMO (and anyone correct me if I'm wrong), suppressing a springer is a bit like trying to suppress a revolver. The springer mechanism noise can't be reduced without tuning down the power and that is probably half (maybe??) the total noise of a springer. The muzzle noise reduction from a quality airgun use only moderator will likely be in the 5-6 dB range. To your ear as the shooter I don't think you'll notice a significant diffrence at the end of the day.

FYI this is my HW95L .22 shot cycle at 17 FPE from an iPhone held about 5' to the side. Turn up your volume to hear the sound.

I have a couple of springers with moderators. I compared an older HW97 with long barrel and a new model with removable muzzle cap. On the new model I installed two rubber grommets to see if there was any change in sound when firing, but I couldn't tell and later removed them.
Recently I tried a screw on HW moderator with my HW98 and there isn't a noticeable difference even after a tune kit was installed.
I also have a couple of old Diana 45s. One has shortened barrel and Mac1 Gen 2 brake and the other has a stock barrel. Not much difference in report, but they're not shooting above 12 ft lbs. I plan to do some testing soon with noise measuring app and chrony.
As mentioned there isn't much of a noticeable reduction in noise at the firing line and a tune might be the most effective way to reduce noise with springers. There may be some reduced volume downrange when using a moderator or with higher velocity rifles.

Well...
I had a Crosman Fire a while back and as you say, the mechanism was VERY LOUD (Nitro piston), but I never heard the impact of the pellet UNTIL I made a slip-on DIY moderater/silencer and attached it to that gun. Not only could I actually hear the impact of the pellet, I also was able to get a LOT more shots at the pests I was targeting as they did not flee so much as they did before I had the suppressor installed. Of course, the pests DID learn to run after the first shot over time... (chuckle)
Not much you can do to quiet most springers/NP airguns as far as the mechanism, but believe me, it IS worth quieting down the muzzle report!!! (smile)
Just a few thoughts from my own personal experience. A more quiet airgun has MANY benefits! (smile)
p.s.
Referring to the OP:
I don't think a "muzzle break" will do much to suppress/quiet the muzzle report, but it *might* improve accuracy... maybe...kinda...sorta...if you are lucky... (smile) YMMV

anecdotal, but i got a -10dB and more consistent shot noise-level with a DonnyFL KOI on a Walther Parrus .177 magnum break-barrel.

No question, the Koi is an excellent moderator. No dB data but it's night and day on my Crosman 2240.

All else being equal (spring tune & pellet weight) a longer barrel will yield a lower muzzle pressure, less noise accordingly.
