(electromagnetic radiation, frequency 300 Hz to 3 kHz)

Ultra low frequency (ULF) radiation is electromagnetic radiation defined by the ITU to be within the frequency range of 300 Hz to 3 kHz. It is considered within the lower-frequency end of the radio spectrum, or beyond (i.e., subradio). It falls between super low frequency (SLF) and very low frequency (VLF).
