I spent a bit of time spannering on cargo Heralds and used to make a bed on the boxes as far back as possible to get away from the noise.
One of our captains announced one night that he had just clocked up 10,000 hours on the Herald. He was a bit deaf.
I can't remember the Darts on the Argosy "singing", I found them noisy and was expecting hearing difficulties in later life, which fortunately has't happened.
