ultrasonic
Above human perception
Ultrasonic describes sound frequencies above the range of human hearing—roughly 20,000 hertz and higher.
Bats and dolphins use ultrasonic clicks for echolocation.
The technology appears in medical imaging ultrasonic scans, cleaning equipment, and pest deterrents.
The noun ultrasound is more common in medical contexts: The ultrasound showed twins.
