I can see how the semi-rigid vent tubing could do that (over the standard dryer vent). The flexible one will create reflections/noise cancelling from the internal ridges plus the flexible sides will not propagate sound in the duct unlike a hard surface.

heat pumps don’t seem to be very common here in the Chicago 'burbs, at least so far as I know.

My noise reference point is the CNC lathe and mill in the basement, both between 60 and 70 dB, as I’ve never had complaints from the next door neighbors on those. Those only make noise inside though and our townhomes (built in the 90’s) have pretty good sound insulation.
