…Nightly noise which I am finding excessive is multiple periods of moaning, screaming with swearing as well as loud thrusting noises in the main bedroom…
If you can hear them then they can probably hear you. I recall being told of a similar problem years ago that was solved as follows: The sleepless person got some friends around, they waited till the sounds from the neighbours had peaked and subsided. Then the assembled friends all burst into loud applause. The sounds did not recur.
Of course there is a risk that this might just encourage them.
