What can cause this vibration in my appartment?
Have been living at this place for 2+ years. Somewhere last year a vibrating feeling suddenly started happening, which also has been comfirmed by other people. It continues day and night, but is usually worst in afternoon and evening times. It really messes with my sleep so i'm determined to find the source of it. I've used a accelerometer to measure the vibration, see links below.
Does anyone know what can be the cause of this vibration? I've used the power switch for my own unit but the vibrating feeling still stays present. Could it be the ventilation unit of a neighbour? Or the pipes in the floor? My unit is also close to the elevator. For context: It is a studio unit on the 7th floor of a 10 story building. Any ideas to fix this problem are more than welcome.
