Which term describes sounds with frequencies above 10,000 hertz?

Which term describes sounds with frequencies above 10,000 hertz?

• A. Ultrasonic
• B. Infrasonic
• C. Audible
• D. Subsonic

Answer: (A)

Sounds beyond what humans can hear are described as ultrasonic. Humans typically hear from about 20 Hz to 20,000 Hz, so frequencies above that upper limit are labeled ultrasonic. Infrasonic refers to well below the audible range, audible covers what we can hear, and subsonic is not a standard term for this frequency classification. Therefore, the term that best describes sounds with frequencies above 10,000 Hz is ultrasonic.
