A low hum in UK, CB1 8DN

Usually starting at around 10pm, low frequency sound similar to that of an idling Diesel generator is perceived in my left ear. If sounds as if the source is external to the ear. However, I have observed that the amplitude is sometimes, not always, correlated with the heart beat. While I turn my head, the sound disappears, but only during the horizonatl motion.

Low frequency hum - amplified by confined space - eases using ear plugs, so have ruled out tinnitus - it's almost like a magnetic field, like an energy rather than a Funtington vibration, it

Sounds like a train engine idling in the distance. It's a very low, rumbling. It is intermittent. It mostly drones at the same level, but occasionally pulses without a discernible pattern
