Is the Sybian very noisy?
Sybian motors do not make much sound but the movement of vibration does. When turned up to a high RPM it would NOT be considered quiet. The secret is to not turn vibration all the way up and leave it at a high speed. The upper speeds should be used as a change of pace for a brief moment. It should be noted that vibration does transfer down through a wood structure if it is not placed on a well-padded surface e.g. a carpet with a good pad or place the Sybian on a foam mat. The purpose of the padding is to absorb the movement that is transferred down through the base of the unit.
