A low hum in Derry BT48 8NR

Low freq hum sound more sever at night time, like a drone above building, prevents sleep, not everyone is sensitive to it, driving me crazy at night, can be heard during the day, if you know what to listen for, what�s causing this, a major proper investigation needs done, type of mental torture similar to a water drip Why does so many people experience this phenomenon and not be taking seriously, why is there no proper research to try and identify the cause and what are the long term effects going to be to people�s health. Surely this must be investigated for the benefit of people�s sanity and quality of life.
