Sorry the answer doesn't change: it needs structural work. Don't waste
money and effort by sticking things to the ceiling. There are no magic
materials that provide a certain amount of noise reduction, regardless of
what ignorant manufacturers may write. Noise reduction depends totally
on
the conditions of use, and in your case there is nothing that you can
stick
on the ceiling that will have a worthwhile effect. Get used to the noise
or
move.

There nust be something that would deaden sound...I understand, Tony,
that you don't believe so. "Move out" or "get used to the noise" is all
or nothing.

If someone else has actually tried something or heard of someone else
trying something successfully - let me know.

I am just looking for some reduction in the impact of the noise, not
complete silence.

Honestly there is very little you can do to stop the noise.

The best you could do is hang very heavy "blankets" down each wall, and one
across the ceiling... You're talking several thousand dollars.

If you are going to spend any money on this, it would be 100 times better if
a "spongy" subfloor could be installed upstairs.
