Frequency period

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.

Here are a few examples of low-frequency sounds: Severe weather . Waves . Avalanches.12 Şub 2020
