A high-pitched whistle, squeal, and a child’s voice are high-frequency sounds.
Read moreWhat is the low frequency range?
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 is above Extremely High Frequency?
Extremely high frequency (EHF) is the International Telecommunication Union (ITU) designation for the band of radio frequencies in the electromagnetic spectrum from 30 to 300 gigahertz (GHz). It lies between the super high frequency band and the far infrared band, the lower part of which is the terahertz band.
Read moreWhat frequencies does the military use?
The military services use the 138-144 MHz band to support air-to-ground, air-to-air, and air-ground-air (AGA) tactical communications; air traffic control operations; LMR nets for sustaining base and installation infrastructure support; and for tactical training and test range support.
