If you don't want to pedal really hard and for a long time, the Tacx should be quiet enough. However, you should switch off the road surface simulation. If it really rumbles over cobblestones, it is possible that the neighbour downstairs will ask if you are drilling something :-)

There are not many quieter ones - noise present.

@Gschneussel That was also one of my reasons for choosing the Tacx! See also DCRainmaker: https://www.dcrainmaker.com/2020... and his video: https://www.youtube.com/watch
