Question

how many headz that humans hear​

Answer 1

Explanation:

The human ear responds to frequencies in the range of 20 Hz to 20,000 Hz (20 kHz),18 although most speech frequencies lie between 100 and 4,000 Hz. Frequencies above 20,000 Hz are referred to as ultrasonic. Though ultrasonic frequencies are outside the range of human perception, many animals can hear these sounds.

Answer 2

While 20 to 20,000Hz forms the absolute borders of the human hearing range, our hearing is most sensitive in the 2000 - 5000 Hz frequency range. As far as loudness is concerned, humans can typically hear starting at 0 dB.
