Can anyone corroborate those numbers?

Numbers? No...

A four blade Pawnee going low overhead at full power is still very
loud. The prop does nothing for the engine noise and the Pawnee has
quite a lot of that. What it eliminates is the 'snarl' from high
speed prop tips that is most noticeable to an observer in the plane of
the prop. If 'snarl' is your problem, maybe this is your solution.

The performance loss is noticeable and annoying, but not a deal
breaker in itself.

Clubs I know who've bought them have not been real impressed. For the
price, I'd like to be impressed. Ymmv.
