Many people will ue noise-cancelling headphones to allow them to listen to music at an acceptable level.
This is sadly not how it works. In order for the noise cancelling you need to feed a signal into the ear. It’s not the same as a theoretical cancellation and noise is going into your ear that is designed to make your brain cancel it out. There’s an argument to say that they could be worse for your ears if you use them at higher volume.

Going back to the point raised by the OP, surely the person most likely to suffer ear damage is the person blowing the whistle.

Yes, quite likely. Though if the sound is amplified it may end up being louder than the whistle but it’s unkikely. As it’s part of the job, I would assume tests have been done to look at the exposure of this. After all the op left the station shortly afterwards, the dispatcher is subject to that level each time they blow the whistle.

I have tinnitus. I used to go to lots of loud gigs, DJ'ed in loud clubs, was always listening to music on headphones and refereed football matches. No problems at all, ever.

Then I got Rheumatoid Arthritis and the medication I was put on triggered it.

So, do take care out there but don't stop having fun because things don't always go wrong for obvious or predictable reasons.

While the cancellation will never be perfect, I don't see how noise-cancellation can work in any other way than actually destructively interfering with the noise, which will reduce the noise level experienced by the ear.

I’m sure a quiet word in these people’s ear would do the trick, they may not necessarily be aware of how it comes out to the people around them.

It may be that a figurative "quiet word" is needed, but in a literal sense it might have to be some really loud words, if they've been blowing those whistles with maximum force for a while :D
