It is a low frequency sound/vibration it's like turning up the volume on a subwoofer but without music. it is like a long and sometime flutuating HMMMmmm . Sometime is a stable sound sometimes flutuating. I can feel a discomfort vibrations, it wake me up during night if it start. At first I thought it came from the nearby airport, when turboprop-engine planes stand by with the engine running at idle. But I also heard this sound when the airport was closed. In this period it is very strong, especially indoors. I can clearly hear it when it starts, usually in the evening / night. I tried to unplug the current but nothing. I tried to record it but nothing (may be my phone is not enought). I tried to find the source but nothing. I have to use earplugs and noise canceling headphones, and it drop down but not compleatly off. I still feel the virbrations.

The sound seems to come from the sky, an intense vibration. Similar to the frequencies emitted by a diesel engine of a car with a slight acceleration or a larger engine at slow speed. Someti…

it is like an uneven engine, it doesn't seem to be the AC that is an even hum for example but more like an idling car engine but it feels like coming from the walls. It is not a "sound" but …

Annoying AF. A low rumble like a truck engine revving. I feel the vibration in my whole body and even my eyeballs if I focus on it. Louder at night, but I hear it during most of the day if I…
