Final answer:
The three ranges and their associated frequencies that classify sound waves are infrasound, audible sound, and ultrasound. Ultrasound: Frequencies above 20,000 Hz. It is not audible to the human ear. These frequency ranges help classify sound waves based on their pitch and the range of frequencies that humans can perceive.
Step-by-step explanation:
The three ranges and their associated frequencies that classify sound waves are: Infrasound: Frequencies below 20 Hz. It is not audible to the human ear. Audible Sound: Frequencies between 20 Hz and 20,000 Hz. It is the range of frequencies that most humans can hear. Ultrasound: Frequencies above 20,000 Hz. It is not audible to the human ear. These frequency ranges help classify sound waves based on their pitch and the range of frequencies that humans can perceive.
