People around the world have reported hearing strange sounds from the skies over the past month. Sometimes they describe it as a hum or low rumble; other times it’s a whine, thump, or even a melody. Often the sounds have been recorded and posted online, fueling rumors and conspiracy theories.
The explanations are almost as varied as the sounds themselves. There’s not a single blanket explanation for all the mysterious sounds, though many have been identified. For example there’s the recent “midnight roar” reported in Malaysia.
There are a few things to keep in mind about these strange, ambient sounds; for one thing, there is virtually no place on the planet where noise pollution is not a problem. We live in a constant sea of background noise, most of it unnoticed until we start paying attention to all the sounds and focusing on them.
Mysterious sounds are nothing new, of course. The most famous mystery sound in the world is probably the Taos Hum, a low-frequency rumble heard by some residents in Taos, New Mexico since the early 1990s. Not everyone hears it, but the earwitnesses who do variously describe it as sounding like a running refrigerator or a buzzing bee. Researchers have been unable to pinpoint the source of the sound — or even confirm that the hearers are indeed perceiving a specific, identifiable sound.
While the public may assume that locating a sound is easy, it’s not. Identifying the source of a sound is very difficult in urban areas where concrete, glass, and buildings can reflect, change, and amplify sound waves from ordinary sources. Of course it’s more fun to think that the mysterious sounds are part of an alien invasion or secret military experiment than machinery at a local sewage plant.
