Concorde!
Everyone knows that concorde used to fly at twice the speed of sound,
so what i want to know is would you still be able to hear the engine noise from the aircraft?
I only asl because acording to the theory if you are going 2 x speed of sound that means you should leave the sound behind you?

Yes but noise is coming from the vibration the sound causes through the airframe and therefore travels through the fuselage! Also, sound can travel up the cabin from back to front at the speed of sound even though it is moving at Mach 2!
Most of the noise is air noise from airflow, not engine noise anyway.

Correct. The only thing he cannot here is the acustically propagated sound behind him, e.g. the roaring afterburners.
That's the same with every supersonic aircraft.
From personal experience I can tell you that supersonic flight is normally very much calmer than subsonic.

loud is always relative - is it louder than another Tupolev? Is it louder when subsonic or when supersonic?
I cannot tell, since I've never been inside a TU-144, as I have never been inside a (flying) Concorde. I just explained the physics.

Cabin noise on Concorde seemed to me to be at a higher pitch than subsonic but not any more intrusive than say a 747. Well as far as I remember having usually been filled with Dom Perignon, Puligny Montrachet and Bran Cantenac etc!
The stability during turns at low level leaving JFK was so reassuring and the lack of serious turbulence on every flight but one made each trip a delight. Cabin air was fresh - untill the cigars lit up!

Was in a 767-300 on a westbound track on a nice sunny day. AF Concorde passed us high above. Amongst the standard noise of our own cockpit, there was a distinct thud from the sonic boom. Very mild, like a dull thud from a hand slap on the fuselage outside the cockpit. Pretty cool though. 
Relative speed difference was like watching a contrail high above while sitting in a patio chair outside.

Concorde boom movie
Not quite the same thing, but pretty neat all the same.
Surprised at the suggestion that cabin noise was much the same as 747. One of my major recollections of my (one and only) Concorde ride was what I perceived as the relatively high vibration and noise levels. That and the rate of climb from the runway.
