I am guessing you are talking about earplugs. I would postpone using that if I were you until I have no options left. They will make your ears hurt when used for prolonged period of time. I can relate to what you are saying, I, for instance, suffer from noisy uncivilized refugees neighbors that keep banging on the floor day and night. The best option I have is using white noise, maybe something out of YouTube but most of the times, I keep a running air fan in my bedroom. I know it is our legal right to be protected against noise pollution and disturbing of peace but who have the resources to claim that right anyway.
