Its depends sometimes is as loud as a helicopter if tuned into it, almost pulsing, like a washing machine. othertimes a bit quieter a bit like a bathroom extraction fan pulsing with wind outside. I first heard the hum when we moved house in 2012 from the city (down low in the valley) to 2 miles out of the city on a hill. sheffield is industrial we can hear music on other valleys or if parties. we moved again in 2019 and can still hear it but worse, higher up now. i ruled out in old house boilers, sky boxes, tvs (though i can hear the electricity if that makes sense) and fridges. alwaya thought it may be next doors washing machine or boiler, but then only i heard it. people laughed thinking im over sensitive.
