Yes, but this is just an upper bound, chosen for some inscrutable marketing reason.

Professional measurement of the sound level of the Vision 3D was around 35 dB, and this one should be even lesser.
That's good, but 35db is not good for a non-gaming PC, so how much less is important. Looking at the earlier pics of the internals, there is just one fan, so if you took a low power version, replaced the fan if necessary, and added something to dampen/isolate the hard drive somewhat, or better replaced it with an SSD, you could have a very quiet system.
