I have even worse noise in my area — a widespread ground vibration across a few kilometers, like a constant loud 50Hz hum that causes a tingling sensation in my body. You can’t even block it by covering your ears. I've been experiencing this frequently, both thru the night and during the day, for the past five years here in Singapore has affected my sleep rhythm, can't sleep with that noise. I've unemployed for the past 5 years.
