Oh, dear! That is the pits!!!
It is an amplification of sensory information...and really can be so incredibly distracting and also very painful!

I go through this, too. I would not wish it upon anyone!

I am a bit over stimulated right now, in fact. I need the air conditioners going, because the heat and humidity set off more neurological pain and other symptoms. Yet, eventually, the noise becomes so loud!
Once it gets that "loud," it can then also become distorted!

What to do?

I do several things, depending upon what my options are at the time.

I can find a way to calm my central nervous system. This can include deep breathing exercises, etc. I do try to eliminate as many noises as possible, especially ongoing background noises. (Not always possible.)
Sometimes, ear plugs help me; other times, not so much!

Sometimes I have to use a med to calm my CNS a bit.

I think, for me, timing of the intervention is everything!
The earlier I "catch it" the better!

I am tired just now, sweetie! I am going to have to think on this.
I will write again when my mind is clearer..and my AC is not buzzing through my head!!! LOL!

Can you get away from the noise? Or can you eliminate it?
Maybe you are asking about what to do when one cannot escape it in any way?

This is a great question! I, too, am very interested in any answers!

I hope you can sleep well tonight ((GmaSue!)))
