Sound that has the audible frequencies, usually between 20 and 20000 Hertz (cycles/second). Sub-sonic refers to the frequencies below 20 Hz and ultrasonic refers to frequencies above 20 kHz (20,000 Hz). Sub-sonic and ultrasonic sound waves are not audible to humans but other animals can hear some of the frequencies.
