People Have Heard an Unexplained Hum for 50 Years — It May Be Coming From Inside Their Own Heads

For decades, a perplexing low-frequency hum has been reported across the U.S., Canada, the U.K., and Australia, baffling scientists and frustrating listeners. New research suggests this mysterious sound might actually be linked to low-frequency tinnitus, a condition where individuals hear phantom sounds. This revelation could finally explain why not everyone perceives the hum, pointing to a potential neurological origin rather than an external source. The discovery is significant as it could provide relief to those affected by the unexplained noise, offering a new perspective on how our brains process and perceive sound.
