Speed has nothing to do with where you are. You can travel below the speed of sound pretty much anywhere.
In subsonic flow, the flow velocity is less than the speed of sound. This means that disturbances in the flow cannot travel faster than the speed of sound, preventing the formation of shock waves. Without the necessary conditions for shock wave formation, subsonic flow remains smooth and continuous.
The main difference is the speed of the object in relation to the speed of sound. Subsonic refers to speeds slower than the speed of sound, while supersonic refers to speeds faster than the speed of sound. In the case of supersonic speeds, objects are traveling faster than the speed at which sound waves propagate in the medium.
The speed of a cruise missile can vary depending on the type and model, but generally, they can travel at speeds ranging from subsonic (less than the speed of sound) to supersonic (faster than the speed of sound). Some cruise missiles can travel at speeds exceeding 600 mph.
A subsonic aircraft flies below the speed of sound, so it does not break the sound barrier. A sonic boom is created when an object travels at or above the speed of sound, causing a buildup and release of pressure waves that result in a loud noise. Since a subsonic aircraft does not exceed the speed of sound, it does not generate a sonic boom.
Subsonic bullets, which typically travel at speeds below the speed of sound (about 1,125 fps or 343 m/s), are commonly used in suppressed firearms to reduce the noise created by the bullet exceeding the speed of sound. These bullets travel at velocities below the speed of sound to minimize the supersonic crack produced when breaking the sound barrier.
Subsonic speed refers to speeds below the speed of sound in a medium. In water, the speed of sound is higher than in air, so typical speeds of objects moving through water are considered subsonic.
subsonic
Subsonic means "slower than the speed of sound" so a subsonic bullet is any bullet that travels slower than the speed of sound.
subsonic is moving below the speed of sound, supersonic is faster than speed of sound
Subsonic means any speed below the speed of sound. (Mach 1). So subsonic aircraft range from 0 - 661 knots at sea level. (Mach 1 is 661 knots at sea level.)
Subsonic
Less than the speed of sound in that medium.
Transonic speeds are when an object is moving near the speed of sound, experiencing a mix of subsonic and supersonic airflow. Subsonic speeds are when an object is moving at speeds below the speed of sound. At transonic speeds, airflow can become unpredictable, leading to effects like shock waves and buffeting.
In subsonic flow, the flow velocity is less than the speed of sound. This means that disturbances in the flow cannot travel faster than the speed of sound, preventing the formation of shock waves. Without the necessary conditions for shock wave formation, subsonic flow remains smooth and continuous.
One half the speed of sound. This is subsonic.
The main difference is the speed of the object in relation to the speed of sound. Subsonic refers to speeds slower than the speed of sound, while supersonic refers to speeds faster than the speed of sound. In the case of supersonic speeds, objects are traveling faster than the speed at which sound waves propagate in the medium.
The term subsonic can refer to speed that's lower than the speed of sound. In computer terms, this could mean an open source media server or refer to programming code.
