How loud is the FX Crown arrow barrel shooting?

I saw this UA FB posting with a young girl who had shot a buck with the Fx Crown arrow barrel.
How loud is this shooting?   IIRC Matt Dubber mentioning the verminator was somewhat loud.

Talking about this post:  https://www.facebook.com/UtahAirguns/photos/a.573466162817049/1451969108300079/?type=3&theater

I'm wondering if it's anywhere near backyard friendly.

Thanks for any insight!

I've done it with the condor,and it is LOUD!!! I see no reason the FX would be any different. However, a  big bore LDC could be fashioned for it using a shroud. Issue s the bottle in the way to do it. that was the advantage using the Conor. Bottle in the back of stock.
