Princeton's WordNet

  1. supersonicadjective

    (of speed) greater than the speed of sound in a given medium (especially air)

    "a supersonic bomber flies so fast that it must release its bombs while the target is still over the horizon"

  2. supersonic, ultrasonicadjective

    having frequencies above those of audible sound


  1. supersonicadjective

    Moving at a speed greater than the speed of sound in air; -- this speed varies with altitude, since the speed of sound varies with altitude, as well as with temperature and humidity, being approximately 1129 feet per second at sea level and 984 feet per second at 16 miles altitude.

  2. supersonicadjective

    Capable of moving at speeds higher than the speed of sound; -- of aircraft.


  1. supersonicadjective

    ultrasonic, having a frequency too high to be audible

  2. supersonicadjective

    greater than the speed of sound (in the same medium, and at the same temperature and pressure)


  1. Supersonic

    Supersonic speed is the speed of an object that exceeds the speed of sound (Mach 1). For objects traveling in dry air of a temperature of 20 °C (68 °F) at sea level, this speed is approximately 343.2 m/s (1,126 ft/s; 768 mph; 667.1 kn; 1,236 km/h). Speeds greater than five times the speed of sound (Mach 5) are often referred to as hypersonic. Flights during which only some parts of the air surrounding an object, such as the ends of rotor blades, reach supersonic speeds are called transonic. This occurs typically somewhere between Mach 0.8 and Mach 1.2. Sounds are traveling vibrations in the form of pressure waves in an elastic medium. Objects move at supersonic speed when the objects move faster than the speed at which sound propagates through the medium. In gases, sound travels longitudinally at different speeds, mostly depending on the molecular mass and temperature of the gas, and pressure has little effect. Since air temperature and composition varies significantly with altitude, the speed of sound, and Mach numbers for a steadily moving object may change. In water at room temperature supersonic speed can be considered as any speed greater than 1,440 m/s (4,724 ft/s). In solids, sound waves can be polarized longitudinally or transversely and have even higher velocities. Supersonic fracture is crack motion faster than the speed of sound in a brittle material.


  1. supersonic

    Supersonic refers to speeds that exceed the speed of sound (Mach 1, approximately 343 meters per second or 767 miles per hour at sea level). In the field of aerodynamics, any object, sound wave, or aircraft moving at such velocities is said to be traveling at supersonic speed. It's often used in relation to aircraft that can travel faster than the speed of sound.

Examples of supersonic in a Sentence

  1. Boom CEO Blake Scholl:

    Supersonic flight will be a critical driver of human progress, and we believe Europe's citizens will embrace it, we know noise is a sensitive issue, and we are designing with that in mind.

  2. Tom Ballantyne:

    Because of the sonic boom it will only be able to fly at supersonic speed over the oceans, in other words unpopulated areas, there will also be restrictions at many airports because a Concorde is very noisy.

  3. Elon Musk:

    These things are much more important than creating electric supersonic VTOL.

  4. Kevin Bowcutt:

    When you look at the problem of getting from Point A to Point B anywhere in the world, the question is how fast do you want to go and how fast is fast enough? supersonic isn’t really fast enough to go overseas and back in one day. For the business traveler or the military, where time is really important, that’s an interesting point. Mach 5 is where you can do that. You can get across the Atlantic in about 2 hours and across the Pacific in about 3 hours.

  5. Daniel Edgington-Mitchell:

    Even if you built something new, I think you are going to be struggling, i think that is why there is such a push in the United States to reconsider the standards particularly for supersonic aircraft because it is just going to be really difficult.
