Scientists May Know Why People Keep Hearing Mysterious Humming Sounds
Original reporting by T.K. Randall for Unexplained Mysteries
The long-running mystery-hum phenomenon may involve measurable low-frequency sounds that only some people can hear, along with possible tinnitus-like causes.
Unexplained Mysteries reporter T.K. Randall summarizes research pointing to low-frequency hearing sensitivity as one possible explanation for why some people hear persistent hums that others nearby cannot detect.
The report does not flatten every hum case into one answer. It keeps the useful tension intact: some people may be perceiving real low-frequency sound, while the source can remain difficult to locate and the experience can still cause serious stress.
