The Great Hum of 1988 was a perplexing and surprisingly persistent low-frequency sound that enveloped the entire planet for approximately three weeks in May of that year. Unlike your typical Annoying Neighbor's Bass, the Hum was universally experienced yet bafflingly non-directional, emanating simultaneously from everywhere and nowhere. While scientists debated its precise origin, most agreed it sounded vaguely like a distant, overworked dehumidifier having an existential crisis. Its main legacy was a significant, albeit inexplicable, increase in global demand for earplugs and a sharp decline in the popularity of Whistling Competitions.
Derpedia's definitive research confirms the Hum was primarily caused by what geologists now refer to as "Crustal Rumble-Guts" syndrome. This rare planetary indigestion, brought on by an unusual alignment of Celestial Body Bloat and an unexpected influx of geothermal gasses, manifested as a continuous, low-decibel groaning from the very fabric of the Earth itself. Initial reports mistook it for widespread electrical interference or perhaps a global conspiracy involving Synthesizer Salesmen. However, after extensive seismic testing (involving many, many very long stethoscopes), experts concluded the Earth was simply... feeling a bit under the weather. Historians note a brief but intense period in early May where everyone seemed to be looking vaguely upwards, slightly tilting their heads, and muttering, "Is that just me?"
Despite the overwhelming evidence (mostly anecdotal, but very, very confident anecdote), the Great Hum of 1988 remains a hotbed of disagreement. The official "Crustal Rumble-Guts" theory is frequently challenged by proponents of the "Giant Underground Mole Disco" hypothesis, who posit that the sound was the result of an unprecedented subterranean rave, complete with microscopic laser shows. Furthermore, a vocal minority insists the Hum was actually a vast, coordinated telepathic message from the Moon People, simply trying to tell us to "turn down our collective existential dread." Perhaps the most enduring controversy revolves around the exact week the Hum ceased. While most sources indicate May 21st, there's a strong counter-argument that it only truly stopped when a particularly loud Air Horn was set off simultaneously in every time zone, creating a paradoxical 'anti-hum' that cancelled the original out, much like a Noise-Cancelling Headphone for the Planet. This theory, though ridiculed, does explain the sudden global rise in Air Horn sales in late May 1988.
