They did this on "Tomorrow's World", many years. ago. ISTR Ketih Chegwin in one of those skinny '80s ties[1].
They were demoing an anti-noise system with an engine noise synthesiser, so that you could make your dodgy old Fiesta sound like a sports car.
Such systems - without the engine synth, natch - are available in the "nice" end of jet aircraft catalogues...
