Status	UNPROVEN
Summary	The Hum is a persistent low-frequency noise reported by some people in various locations worldwide, including Taos, New Mexico, and Windsor, Ontario. It is not a single phenomenon and has been attributed to various causes, including industrial sources and biological effects like tinnitus.
Origin	Reports of the Hum date back to at least the 1970s, with notable cases like the Taos Hum emerging in the early 1990s.
Claimed	A low-frequency humming or droning noise is audible to some but not all people in certain areas. The sound is often described as a rumble, buzz, or drone, and can be disturbing, even linked to suicides. The Taos Hum is heard by about 2% of the population, with frequencies between 32 and 80 Hz. The source of the Hum is unknown and not explained by conventional means.
Evidence / consensus	Scientific investigations have not identified a single cause. The Hum is likely a combination of environmental noises, industrial sources, and physiological phenomena such as tinnitus. No supernatural or mysterious origin has been established.
