2. Capable of moving, or utilizing air currents moving at supersonic speed.
3. Of or relating to sound waves beyond human audibility.
Any speed over the speed of sound, that is approximately 343 miles per second, 1,087 feet per second, 761 miles per hour or 1,225 kilometers per hour in the air or at sea level, is said to be "supersonic".
Speeds greater than five times the speed of sound are sometimes referred to as hypersonic.
2. The location, measurement, or delineation of deep structures by measuring the reflection or transmission of high frequency or ultrasonic waves.
Computer calculation of the distance to the sound-reflecting or absorbing surface plus the known orientation of the sound beam gives a two-dimensional image. Also: sonography.
