Low frequency (LF) is the ITU designation for radio frequencies (RF) in the range of 30–300 kHz . Since its wavelengths range from 10–1 km, respectively, it is also known as the kilometre band or kilometre wave. LF radio waves exhibit low signal attenuation, making them suitable for long-distance communications.
Read moreWhat uses low frequency waves?
The Low Frequency (LF) band is mostly used for AM broadcasting in Europe as well as in areas of Northern Africa and Asia . Similar to VLF, LF can also be used for navigational radio beacons. It can also be used for maritime ship-to-shore communication, as well as transoceanic air traffic control.

Extremely low frequency (ELF) is the ITU designation for electromagnetic radiation (radio waves) with frequencies from 3 to 30 Hz, and corresponding wavelengths of 100,000 to 10,000 kilometers, respectively . In atmospheric science, an alternative definition is usually given, from 3 Hz to 3 kHz.

Abstract. Low frequency noise, the frequency range from about 10 Hz to 200 Hz , has been recognised as a special environmental noise problem, particularly to sensitive people in their homes.
