@PeteLittle1970 @actuallyautistic I've listened to various noises very briefly - white, pink, brown etc. I find natural sounds, or ambient music much more effective. I think I need a bit more variation than the pure noise. But I don't feel confident in saying this as I've not done more than listening for a moment and going on my first reaction.

Ocean and rain sounds, and distant thunder are incredibly soothing to me.

I don't see a link to your tracks in your profile - is there somewhere where one can listen to them?
