What term describes frequency greater than 20 kHz?

Explanation:
When we categorize sound by frequency, we compare it to the range humans can hear. The upper limit of human hearing is about 20 kilohertz. Frequencies above that threshold are not audible to us and are called ultrasound. This term is standard across fields like medicine, where high-frequency sound waves are used for imaging, and in industry for cleaning or detecting flaws. Infrasonic describes frequencies below the audible range (below 20 Hz), which are also not heard by humans. Hypersonic isn’t the typical label used for these acoustic frequencies in this context. So, the term for frequencies greater than 20 kHz is ultrasound.
