A low hum in UK Leicester LE32BL

Distant idlling diesel engine The noise is definitely an external source. Would personally like to test with elf and ulf microphones but too costly.Also interested if seismic sensors are picking up any low level murmurs. Considering all my hearing problems I can still hear, and almost feel(with the resonance) the hum very clearly, even with/through the tinnitus.

Symptoms: Ear discomfort (pain, fullness, throbbing), Insomnia, Anxiety, I am certain the low frequency din is a external source.
