A low hum in Ireland, Dublin
Low frequency slowly oscillating, like a large engine idling in the distance or a subwoofer with an unplugged audio jack playing a low drone. The source does not appear external as earplugs do not stop it, it feels more like my eardrum is vibrating along with a waveform. Usually only audible at night when it’s quiet. I have tinnitus so have always assumed it was some form of low frequency tinnitus. It can be louder than my tinnitus when it’s present, however it is not omnipresent sometimes it’s not there at all. Its presence is not location dependent, I have heard it anywhere it’s been quiet enough. I work late so am usually awake untill early hours of the morning so hear it most nights.
