What frequency range is the human voice?

In general, the fundamental frequency of the complex speech tone – also known as the pitch or f0 – lies in the range of 100-120 Hz for men, but variations outside this range can occur. The f0 for women is found approximately one octave higher. For children, f0 is around 300 Hz.

What is the lowest frequency radio wave?

kHz
Bands of radio waves

Band	Frequency range	Wavelength range
Very Low Frequency (VLF)	3 to 30 kHz	10 to 100 km
Low Frequency (LF)	30 to 300 kHz	1 m to 10 km
Medium Frequency (MF)	300 kHz to 3 MHz	100 m to 1 km
High Frequency (HF)	3 to 30 MHz	10 to 100 m

What is Low frequency transmission?

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.

What is low-frequency sound?

Also called infrasound, low-frequency sounds stand for sound waves with a frequency below the lower limit of audibility (which is generally at about 20 Hz). Low-frequency sounds are all sounds measured at about 500 Hz and under. Waves.

What is UHF frequency range?

between 3,000 and 300 megahertz
UHF, abbreviation of ultrahigh frequency, conventionally defined portion of the electromagnetic spectrum, encompassing radiations having a wavelength between 0.1 and 1 m and a frequency between 3,000 and 300 megahertz. UHF signals are used extensively in televison broadcasting.

What are low frequencies used for?

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.
