From TFA, the shockwaves released that are used to ignite new detonations travel at Mach 5 within the combustion can. At that speed, with the minute distances involved, I very much doubt this would sound like the Aurora was fabled to sound like.
I think more likely it would sound like an amped-up version of the V1 Flying Bomb.

If the engine had a ring with a diameter of 1 foot, which seems reasonable compared to other rocket engine combustion chambers, a mach 5 detonation shockwave would circle the combustion chamber at 1.7 kilohertz, which is quite a high-pitched tone (though not as high as the whine of a jet engine).
