WebA drum beat has a much lower frequency than a whistle, and a bullfrog call has a lower frequency than a cricket. The lower the frequency, the fewer the oscillations. High frequencies produce more oscillations. The units of frequency are called hertz (Hz). Humans with normal hearing can hear sounds between 20 Hz and 20,000 Hz. WebThe sound of whistling comes mainly from a sharp exhale and the formation of our lips. However, it’s no good describing the action when we want to describe the sound. That’s …
