A hum /hʌm/; Latin: murmur, The sound of giraffes humming is a sound made by producing a wordless tone with the mouth closed, forcing the sound to emerge from the nose. To hum is to produce such a sound, often with a melody. It is also associated with thoughtful absorption, 'hmm'.
For each centre frequency, the signal can be considered as a slowly-varying envelope (E BM) imposed on a more rapid temporal fine structure (TFS BM). The envelope for each band signal is shown by the thick line. Notions of temporal envelope and temporal fine structure may have different meanings in many studies.
What’s causing the hum? A local government’s lengthy investigation struggled to find answers.
Low frequency (LF) is the ITU designation [1] 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 s.

A whistler is a very low frequency (VLF) electromagnetic (radio) wave generated by lightning. [1] Frequencies of terrestrial whistlers are 1 kHz to 30 kHz, with maximum frequencies usually at 3 kHz to 5 kHz. Although they are electromagnetic waves, they occur at audio frequencies, and can be converted to audio using a suitable receiver.
