A low hum in 64743 Aschaffenburg, Germany
Like a constant low-frequency humming noise, like an idling diesel engine at around 67 Hz. Quite often very invasive. The local environmental authorities ran some audio recording with a class 1 phonometer. They were not able to confirm 67,x Hz (actually did not find it at all), but several frequencies as multiples of 8,x Hz. Is 67 Hz,x a harmonic generated possibly just in the ear?
What they reported
