The sound you are hearing could be coming from bad Tires. As the Tires Feather because of misalignment or suspension issues, they develop an uneven wear pattern. If the noise gets louder as your speed increases, this could be your problem. Get to a Tire Dealer and have your Tires and Suspension Checked. :-) Another noise that sounds like a tire noise is a wheel bearing going bad. IF you take you hand and feeling the tread around the tire, you can tell if there is a smooth feel or a wavy feel or choppy feel etc. Anything other than a smooth feel could cause a roar. IF your struts are original, they may be causing a choppy wear.
engine
The sound of the airplane from the outside is pretty loud BUT when you get inside of an airplane and your flying you cant hear any thing
If the sound is coming from inside the engine, an internal part has failed.If the sound is coming from inside the engine, an internal part has failed.
Turbine noise, Jet Engine rumbling,
A boom. However, for anyone inside the airplane they do not hear anything. Older planes not build for supersonic speeds could shudder and vibrate due to the turbulence.
NO it will not. If you have a knocking sound then you have trouble inside of the engine.
No, the i in airplane is silent.
Sound is a mechanical wave. It needs material medium to travel. The sound from the airplane reaches your ear through air in the form of alternate compressions and rarefactions.
rumbling
The aircraft used in the 1980 comedy film Airplane! was a modified Boeing 707. One of the comedic touches is that when the plane (a four-engine jet) is in flight, the sound effect is that of a propeller-driven aircraft.The shuttle that is flown in the sequel Airplane II was the Mayflower.
A marble sound under load indicates the engine is out of time. Have the ignition timing checked and the timing chain/belt for damage or excessive play.
An airplane, because it starts with a vowel sound. (In the UK you would say an aeroplane.)
