Answer 2

Answer:

Frequency is measured in hertz (Hz). For sound, this means the number of pressure waves per second that would move past a fixed point. It is also the same as the number of vibrations per second the particles are making as they transmit the sound. ... Humans can normally hear sounds between 20Hz and 20,000Hz (20kHz).
