my son is 26 and lives on his own. He cannot live with us as it is too stressful for him he needs his own space. He currently lives in a flat but he hears the neighbour upstairs and focuses on it and gets stressed as it stops him getting to sleep. I have given him earplugs to use but he finds them uncomfortable. Any advice would be greatly appreciated how he can block out noise. Apart from moving to a the middle of nowhere is there any thing that helps deal with this ?
