Is the mystery of “The Hum” solved?

News.com.au reports that scientists believe they have discovered the source of the mysterious hum that “can drive [some] people to the brink of madness.” For those who can hear it, “‘The Hum‘ can cause sleepless nights, stress and nosebleeds and is described as a relentless ‘kind of torture’ with no explanation.” Various theories have been bandied about as to the source–submarines, gas pipes, and even mating fish–but in the end the explanation is far less fanciful. Scientists Fabrice Ardhuin, Lucia Gualtieri, and Eleonore Stutzmann believe that the “microseismic activity, recorded everywhere on Earth, is largely due to ocean waves.” So how do ocean waves make the hum? The scientists postulate that “the pressure of the waves on the sea-floor causes the earth to vibrate like a bell and creates a sound that is heard more by some than others.”

Of course the answer won’t bring relief to those who suffer from the hum (known as “hummers”), but it may help them from being misdiagnosed with tinnitus.
