Worried about the neighborhoods
I can tell Galileo at full frequency do not transmit any vibration to the ground. However depends how you train. If you work correctly there is no noise thru the pavement and walls. I live in a flat at the third floor and train every day with a Galileo Advanced. Nobody said a word over three years.
Every other device I try was quite noisy and vibrations are transmitted to the ground depending the frequency you use. So if your concern is to maintain good relationships with the next door people, you have to consider this aspect, yes.
