I just finished with drywall my 22' by 24' garage with vaulted ceiling which is 16' feet high at the top. Epoxy garage floor. Makes a great little indoor basketball/sport court. The problem is lots of echo and loud. When I had drywall done I didn't have them put texture on ceiling and which I would have to help reduce noice. I'm looking for ways to reduce. Thoughts? Here are a few ideas I had:

1) use a 6" inch knife and manually spread a texture on ceiling
2) have the ceiling sprayed with knockdown
3) have both ceiling and some of walls sprayed with knockdown
4) put up acoustic panels on a few walls (no idea how many would be needed)

Would any of those solutions be effective and/or looking for more. thank you

Check out USG Acoustical Plaster Finish.
Also look at Pyrok Acoustement Plaster this company has many to chose from most require spray equipment.
Look at the Star Light system by Pyrok it is installed in panels than skimmed coated this one is some kind of glass fibers cover your body when working with it.

I would use sound absorbent panels.

We had to install sound absorbing panels behind our choir at church. I kept getting delayed reverberated sound from the back wall and I couldn't mix it out using the digital board. With the panels, it is quiet with regards to the reflected sound. So they work.

Edit: you may get good results by simply hanging flags from your favorite teams, or sponsors from the vault. Anything to disrupt the sound waves.

You could try some stick-on carpet panels on the walls—doubt it'd work on the ceiling though!

Carpet typically does not have a low enough flame spread rating for vertical surfaces unless it is specifically made for walls.
