In my country there would be one of 2 issues here (or both):

A Disturbing Noise is objective a scientifically measurable noise level and generally compared to the existing ambient noise level.
A Noise Nuisance is a subjective measure and is defined as any noise that disturbs or impairs or may disturb or impair the convenience or peace of any person.

So looks like it would be Noise Nuisance and have no idea what this entails in the UK, since you are saying that the disturbing noise is below the threshold (10db) which deals with the disturbing noise levels.

You are more than likely dealing with someone who normally gets their way by saying she will call the council.

Good luck

The only thing close i believe would be the "Environmental Protection Act 1990" 79(1)(g)

(g)noise emitted from premises so as to be prejudicial to health or a nuisance;

But they would have to specifically prove 5 bitcoin miners are causing them ill health, since i have a letter written from the neighbours stating their problem was "they couldn't enjoy their garden"

To prove it was a nuisance i would iterate the fact they also live next to a bus stop and 2 student accommodations as well as living under a known flight path
