Hi i am going to make a bb gun but i have never made one before and i was wondering how much sound they make.
I want to make a silencer for aesthetics but if a bb gun makes a lot of noise then i would like to know a good way make a silencer that actually gets rid of sound... not just looks good

It depends what sort of BB gun you're making. If you're using compressor pressures, say up to 120 psi, it's usually hardly worth the effort of making a suppressor. It's when you go into the higher psi ranges (300 psi+) using fast valves that things get annoyingly loud.
You can avoid making a suppressor however using the
SWOS principle, that is to say using a small chamber volume in proportion to your barrel, though this would require a relatively long barrel for decent power.

There are many different places in which to look for silencers.
Behind them however, is all the same concept. They are a ported extensions of barrel that have an insulated shroud surrounding this ported part. Much of the noise is blah blah blahblahblahblahblah
Here's a link I liked from
instructables.com
Now, I realize you're making a bb gun, but this will give you the best general idea on how to build one. It gives a good base plan to start off and compare with.
By the time you read this I am guessing you've already found one though.
