Electronic and magnetic components can generate audible signals when they are excited at frequencies in the range of human hearing. This phenomenon has been observed since the early days of electric power conversion. Transformers operating at the line frequencies of 50 and 60 Hz often produce an undesirable hum. It is well known that switching power converters operating at constant ultrasonic frequencies can produce audible noise if their loads are modulated with audio frequency components.
