Why is it not noisy traveling at supersonic speeds?

Untrue. Supersonic aircraft are very noisy, the only indication that the aircraft passes through the sound barrier is a slight increase in acceleration, the Mach meter number, and an announcement by the pilot.


Is a plane a has a high pitch sound or low?

A plane typically produces a high-pitched sound due to its engines and aerodynamic design creating a whining or buzzing noise. This sound can vary in intensity depending on the aircraft's size, speed, and distance from the observer.


Why does an aircraft which has its engines above the fuselage produce less noise than one which has the engines below its body?

If the engine is placed above the body of the plane, the body acts as a shield that reflects or absorbs the noise going towards ground level, much the same way that a wall will muffle sound from an adjoining room


Why do airplanes appear to slow down after takeoff?

After takeoff, airplanes continue to gain altitude while reducing engine power to reduce noise and fuel consumption. This reduction in engine power may give the sensation of slowing down, even though the plane is actually climbing and increasing its speed. Additionally, as the plane ascends, it moves further away from the observer on the ground, which can create the illusion of decreased speed.

What can you expect when landing in an airplane?

Your plane will circle the airport until cleared to land. Don't be surprised when the landing gear is engaged; they sometimes make a loud noise and if it is your first time in a plane it can be scary if you don't know what it is. Once you've heard it, you know to expect it and will know what it is next time. Landing is usually very smooth; you can barely tell when the plane touches ground. Other times, you'll feel a little bump.
