static

static, term formerly use to describe electrical noise in radio reception, especially noise that originates outside a transmitter and receiver, e.g., in the atmosphere or in man-made devices. In general, a frequency modulation (FM) radio receiver is less susceptible to such noise than one using amplitude modulation (AM). Many receivers are equipped with devices, such as automatic limiting and silencing circuits, to lessen the effect of such noise on reception.
