A low hum in Davis, California
Low frequency Hum! I tried to record it on the noise app. But it doesnt pick up low frequency noise. I can hear it now and the local traffic noise does not affect it. The free way i 80 has no sound barriers as it runs straight through Davis. It is around one mile from this house. The house is stucco with dual glazed windows. Some are very old some are new. The sound is less obvious in the newer window rooms.

Very low frequency hum, like the sound a diesel vehicle would do from a distance before getting too close, but constant all the time. I can hear the noise better when it is completely silent…
