I don't think it would come in thru your ear. Maybe resonating inside your body cavity?

- derefr 12y agoI probably just don't know enough about acoustics, but could vibrations with a subsonic period travelling through the earth cause resonations in smaller air-filled cavities (e.g. underground air pockets/caves; the insides of buildings; bodies of water) that would then result in audible vibrations?
- swamp40 12y agoYes, there have been instances of subsonic standing waves/resonance in hallways that have caused feelings of fear and reports of "ghost" sightings.
- cpncrunch 12y agoThat's really just speculation, and it wouldn't likely sound like a "hum". Tinnitus and/or mains hum seems a much more likely explanation.
