What is the audible frequency range for the human ear?

$\huge{ \red{ \boxed{ \boxed{  \pink{ \underline{{ \orange{ \mathscr{answer}}}}}}}}}$

Humans can detect sounds in a frequency range from about 20 Hz to 20 kHz. (Human infants can actually hear frequencies slightly higher than 20 kHz, but lose some high-frequency sensitivity as they mature; the upper limit in average adults is often closer to 15–17 kHz.)
