I have a Brother HS-2000 and it is very quiet until it starts needing a cleanout. I had another Brother that was much louder. I use the HS-2000 primarily because I could use it at 2 in the morning when my light sleeping DH was sleeping just 15 ft away in our motorhome. Of course I don't believe in sewing at full throttle because it's too hard on the parts in the sewing machine & I want to have this one for a very long time. I usually go about mid-speed and that's fast enough for me.
