A 2025 Marine Mammal Science study shows blue whales vocalize at ultra-low frequencies that travel far through seawater, but killer whales hear best at higher frequencies; beyond roughly a kilometer, orcas may largely miss the calls, giving blue whales a private long-range communication channel that could aid predator avoidance and mating, though increasing ocean noise could mask signals.
Residents in Taos, New Mexico, have reported a mysterious, persistent low-frequency hum since the 1990s, which has baffled researchers despite extensive investigations using advanced monitoring techniques. The sound, described as similar to distant industrial machinery, is location-specific and unaffected by ear protection, with no physical source detected. Similar phenomena have been reported elsewhere, but the exact cause remains unknown, with theories exploring electromagnetic influences and sensory perception. The hum is associated with physical and psychological symptoms, contributing to ongoing public concern and scientific curiosity.
