Not really. These spas (and others) move a lot of water, and the valves are pretty close to the outlet of the pumps. This results in some noise. HotSpring went to a six-outlet valve with an open center and it helped a lot. But then they introduced the HP versions with bigger pumps, and they do make noise in certain positions. Not all positions, but some.
I have found that I don't use the one position on my Vista that makes one of the diverters noisy, so I'm lucky. But if I do want to, I set my folded towel on it and the noise goes just about away.
