Fact of the Day: 21/09/2021

Humans have a great range of hearing. We can hear sounds from frequencies of about 20 hertz (Hz) to 20 kilohertz (kHz). Babies can hear frequencies higher than 20 kHz, and humans tend to lose the ability to hear higher pitches as they grow older, with adults typically able to detect a higher limit of 15-17 kHz.
