The sound radiation of cylinder body by structure-borne noise transmits from the motor. gear meshing to the shells. The signal from electrical system and frequency modulation by the propagation wave with the sub-systems excites the structures. One of the methods try to reduce such radiation by the cylinder shells is inserting the notch filter between the source and receiver. The different operative configurations to evaluate the effectiveness and performance presents the efficiency of the notch filter are over 5 to 10 decibels.
