The most noticeable sound from the Javelin was at idle, not so much a blue note but rather a moan, a sound shared by the Victor 1's which also had the Sapphire engine. Nostalgic perhaps but a pain at three in the morning when you are trying to sleep.
Those of us that live in Oxfordshire still occasionally hear the glorious Meteor blue note as Martin Baker have one they operate out of Chalgrove.
The Vampire was renown for the strange sounds emanating from its engine. Indeed the Australians grounded all theirs and came to Fenton in 65 to check on ours only to discover that the Vampire always made weird noises which we considered quite normal, it was when it stopped making weird noises you should start worrying.

bvcu,
I'm surprised. Crewroom opinion at Brawdy was pretty firm on the cartridge ejector chutes. Blue notes were just detectable as a low hum at 360kts on the run in and break into the circuit, rising in volume and pitch with increasing speed all the way up to the IAS limit. The higher one was, the better the note as it was longer lasting.
we had a MK9 at a large airfield in wiltshire that would do a lovely blue note with no cartridge ejector chutes or sabrinas fitted, but gun ports were open. Both MK 6's we had wouldnt do it as the gun ports were faired over . Seem to rember it was a fairly narrow speed band to produce the optimum note !!
I'm told that in the Hunter GT6, some form of note could be generated by winding it up to 480 KIAS plus (not difficult), then flipping the airbrake test switch (gave about 10 deg airbrake).....
Certainly the QFI who came through the 4FTS groundschool 'survival exercise' site very low and at the speed of heat generated a superb noise!
And got severely in the poo with 'Tojo' (the Stn Cdr) as a result.
