Infrasound Anomaly
The Green Bank Silence Zone
Green Bank, West Virginia, USA — first reported Ongoing
Near-zero (notable absence)
The opposite of a hum. The National Radio Quiet Zone bans electronic transmissions. Residents report an eerie, almost painful silence — and some still hear a hum that should not exist.
Theories
- Tinnitus amplified by absence of masking noise
- Geological microseisms from Appalachian fault systems
- Biological infrasound (insect and animal sources)
- The hum of the nervous system itself
