Research and Implementation of a Novel Audio Jamming Technique

A noise jammer is designed in this paper. By transmitting ultra-low frequency (ULF) signals, it can directly block the receiving component of the audio sensor, saturate it and deprive it of the ability to extract and restore the received audio signal, without inflicting any damage on the human and environment. An appropriate source of noise is chosen and modulated in different ways to guarantee that the modulated noise is absolutely irregular. An effective transmission method is adopted to maximize the transmission distance, coverage of frequency spectrum and the level of saturation.
