A human ear can pick up a sound of up to 20,000 hertz. Cats can pick up 60,000 hertz, and dogs can pick up 40,000 hertz maximum.
20 Hertz to 20,000 Hertz is the frequency response range that a human can hear. So in answer to your question 20 Hertz would be the lowest pitch a human can hear.
We can hear from 0 dB, that is the threshold of hearing up to 130 dB that is the threshold of pain.
The nominal human hearing range is 20-20,000 Hz.
20 Hz to 20,000 Hz and they are called Audible Range (Sonic Spectrum).
It is not the speed that matters, but the frequency. Human ears can hear frequencies between about 20 and 20,000 Hz (vibrations per second). In older people, this range becomes less.
The Human hearing range IS the sonic range. Sounds which fall under the ultrasonic range are sounds which emit a higher frequency then we can hear (ie. dogs hear within this range). Infrasonic sounds emit lower frequencies then we can hear. The human hearing range or 'Sonic' range is between 16- 20 000 Hz, though changes with age

Sound waves with frequencies above the normal human range of hearing are called ultrasoundUltrasoundUltrasonic for frequencies higher than a human can hear, and infrasonic for those frequencies below the human threshold of hearing.
Because each animal has a different range of sensitivity for sound frequencies; also not all the human beings are identical.
