Hearing Range of frequencies for humar ears if from 20 Hz to 20,000 Hz.
The lowest frequency is 10 Hz. A human can hear frequencies from 20 Hz to 20,000 Hz. Some frequencies can be felt rather than heard.
20 Hz to 20,000 hz is the recognized range.
Frequencies above 20kHz are not audible to humans. Sounds above this frequency are called ultrasound.

Ultraviolet wave is a portion of the electromagnetic spectrum extending from the violet end of visible light to the X-ray region.Ultraviolet (UV) radiation lies between wavelengths of about 400 nanometres and 10 nanometres, corresponding to frequencies of 7.5 × 1014 Hz to 3 × 1016 Hz.

There are other frequencies, such as 60 Hz, 25 Hz, and 400 Hz in common use. Please restate the question - it does not make sense.
No, that is completely unrelated.
20 Hz to 20,000 hz is the recognized range.
The frequency of x-ray in the range 30 petahertzto 30 exahertz (3 × 1016 Hz to 3 × 1019 Hz) and
infrasounds
A woofer is a loudspeaker that gives out only low frequencies (20 hz to 150 hz).
typically 20-20000 Hz - but this range will decrease with age
