subsonic
The non-dimensional property that is 1 at the speed of sound is the Mach number. It is the ratio of an object's speed to the speed of sound in the medium it is traveling through. A Mach number of 1 means the object is traveling at the speed of sound.
Close! Actually, Mach-1 is the speed of sound. anything above Mach-1 (Mach-(1-5)) is supersonic, all the way up to Mach-5, at which point an object is called "Hypersonic". Sometimes speeds above Mach-10 are referred to as "High-Hypersonic". So, a jet moving at Mach-1 wouldn't actually be traveling FASTER than sound, it would be traveling AS FAST as sound.
The supersonic object is hitting air molecules faster than they can get out of the way, so they pile up.
Sonar uses sound waves to measure distances by calculating the time it takes for the sound waves to bounce back. However, when an object is traveling faster than the speed of sound, the sound waves emitted by the sonar system cannot catch up with the object to bounce back, making it impossible to accurately determine the speed of the object using sonar.
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.
Twice the speed of sound is called Mach 2. This means an object is traveling at twice the speed of sound, around 1,522 miles per hour at sea level.
The non-dimensional property that is 1 at the speed of sound is the Mach number. It is the ratio of an object's speed to the speed of sound in the medium it is traveling through. A Mach number of 1 means the object is traveling at the speed of sound.

When something is traveling at the speed of sound, 343 m/s, it is said to be traveling at mach 1. When traveling at twice the speed of sound it is traveling at mach 2 and so on. Wikipedia.org, 'The World's Encyclopedia' has an entire article on Mack Number. Refer to the related link in the Related Links section below.
I think that the sound will be aborbed by the object then come out the outher side as if you put ear phones on.It keeps the sound in as much as it can.If it is totally covered it will be MUFFLED. new ans: the object will absorb all the energy and the sound will come out muffled.
We generally refer to the sound we hear when a supersonic object passes somewhere in our vicinity as a sonic boom.+++A sonic boom is the shock-wave created by an aircraft accelerating past the speed of sound breaking through a pressure-wave formed in the slip-stream around the aircraft's nose.
The speed of an object traveling faster than sound is referred to as supersonic. For example, the speed of sound in air is approximately 343 meters per second at room temperature. Therefore, any object traveling faster than 343 m/s would be considered supersonic.
A drop in pitch is observed when the frequency of the sound wave decreases. This can happen when an object producing sound moves away from the listener (Doppler effect), or when there are changes in the medium through which the sound is traveling, such as in the case of a sound wave traveling from air to water.

A sonic boom occurs by an object traveling through the air faster than the speed of sound.
