Title: Decibel rating of an AT44 Long?
Post by: AirJaeger on January 08, 2017, 07:08:38 PM

Do any of you fine folks happen to know how loud, in decibels, preferably an AT44 Long in .25 is?

I'm looking to get one and fire it outdoors, and I want to make sure I don't break the town's noise ordinance, but I couldn't find an outdoor rating of it anywhere.

 113 db , I have the at44 pa in .177 and it has a nice loud crack un moderated, perhaps look into the QE version. I have a shrouded Galation and the ping is all I hear then pellet impact.

Thanks! I wanted the unmoderated version for the open sights, But that's REALLY pushing it (The Ordinance says 115db), so I'll get the QE version and stick a dot sight on it.

Thanks again!  ;D

My .22 QE is very quiet and on my phone app came in about 90db.  That is suitable for indoor use.

Get the non QE and put a moderator on it. Then you have open sights.

My AT44 was too loud after some power mods so I was producing 120+ db  :(
Thats why I put a shroud on it... I prefer the shroud over the LDC 'cause I dont want
to make the gun larger.  Put the shroud in a classic AT44W needs to change the barrel guides
a shroud mount over the barrel, some baffles, shroud tube and an air stripper (like mrod)
A bit of work but it was worth it  8)

Here some photos:
