I don't have nuisance neighbours, I have elderly neighbours who are hard of hearing.
We live in a pair of bungalows, with very thin dividing walls.
I work shifts, some night, and during the day it can be difficult getting enough sleep.
I've tried earplugs, lots of different types, none of which work as I seem to have very small ear canals, so earplugs are very uncomfortable, even the ones for small ears.
Just wondered if anyone has used anything on their dividing wall to absorb some of the sound next door?
