Frequency: The number of waves formed by a sound in a specific period of time, measured in Hertz (Hz) Pitch: The relative highness or lowness of a sound, measured in frequency (Hz) Harmony: A combination of two or more notes that sound pleasing when played together
The human ear can typically hear sounds between 20 Hz and 20,000 Hz. Dogs can hear sounds up to 40,000 Hz and dolphins can hear sounds up to 100,000 Hz!
