I’ve been hearing/feeling this humming noise at home and I can feel vibrations. I’ve had trouble sleeping and worsened anxiety ever since this started. I recently downloaded this app that measures infrared sound and I took some screenshots of what I recorded at home with everything off. Can anyone tell me what would be causing that steady frequency around 15Hz? And what would be causing those bright vertical lines that go all the way down to 0? No cars were going by or any other noise that I could hear when those would come up but it’s like I could feel it in my body.
