What I find somewhat disingenuous is a measurement of 8KHz noise being touted as some measure of the device's operation & efficacy - it's misleading. Anybody who genuinely wants to evaluate the Regen has two approaches open to them - listening & measuring - not mutually exclusive. Most people will take the listening route as measurements are really an academic exercise, although they should be interesting if published.

Anyway, there is no such thing as a complete "null" so what "null" do you think is below audibility?
