Abstract :
THE PROXIMITY OF humming electric equipment to dwellings is becoming a concern to the utility engineers. The main cause of this noise is the minute pulsation of the laminations submitted to a 60-cycle-per-second alternating flux. This phenomenon is called the magnetostriction and its intensity depends on the induction present in the steel.
