If you mean the leadscrew gear train, the ones under the cover on left of the headstock, yes, they can be somewhat noisy. They will certainly make more noise than if the Forward/Reverse lever is in neutral.
If it seems overly loud to you, check the back lash on the banjo gears. Too tight, and they will growl a bit. Too loose, and the gears may seem to make a kind of ringing or clanging. Use a piece of printer paper or index card to set the lash, and it may help. Run it between the teeth on the gear train when you set the lash.
If you are running the gears dry, coating them with a little way oil helps, too. Set the lash, a little oil, and as long as the gears are not damaged, whatever noise you hear is just what you are going to get. They do make some noise.
