Those frequencies that are not one of the resonances are quickly filtered out & mdash; they are attenuated & mdash; and all that is left is the harmonic vibrations that we hear as a musical note.

While the trials were largely successful a number of negative points were noted, not the least of which were braking issues and the creation of a harmonic vibration from the train's bogies which caused nausea in otherwise healthy passengers.

An odd-fire V6, on the other hand, shows highly irregular torque variations of 200 % above and 175 % below mean torque, which is significantly worse than an even-fire V6, and in addition the power delivery shows large harmonic vibrations that have been known to destroy the dynamometer.
