Those affected report never having heard noises before, and say the Hum is generally heard indoors and becomes louder at night. In most instances, the affected group only makes up around 2 percent of the population, but for those individuals, the Hum is largely inescapable and impossible to track. ItвЂ™s difficult to pinpoint when instances of the Hum began, but itвЂ™s been well-documented since the 1970s, and since then, cases have popped up all over the world-from Ontario, Canada to Taos, New Mexico to Bristol, England to Largs, Scotland and Auckland, New Zealand. In these cases, there have been reports of a relentless and troubling low-frequency humming noise that can only heard by a certain portion of the population. The Hum has been recorded on several occasions, mostly during the last 50 years or so. The sound, lasting about seven minutes, gradually decreases in frequency, hence the name вЂњslow down.вЂќ Like Upsweep, the sound has been heard periodically since it was initially detected.

Slow Down was first recorded on and is also credited to an iceberg running aground, though some people insist it might be a giant squid. LovecraftвЂ™s fictional sunken city of RвЂ™lyeh, where the creature known as Cthulhu lies вЂњdead but dreaming.вЂќ Cthulhu can best be described as part man, dragon, and octopus, which seems as likely a source as any for the oceanвЂ™s greatest aural anomaly. The most fanciful of all theories stems from the fact that BloopвЂ™s location is somewhat close to author H.P. If an animal was the source of Bloop, it would have to be larger than a blue whale.

Bloop is generally believed to be the sound of a massive icequake, but scientists havenвЂ™t totally ruled out the possibility that the sound originated from something вЂњorganic.вЂќ The sound only lasted about a minute and and was heard repeatedly over the summer, but not since. In 1997 (a big year for auditory ocean mysteries), an extremely powerful, ultra-low-frequency sound was detected at various listening stations thousands of miles apart and traced to somewhere west of the southern tip of South America. Bloop is the big kahuna in unexplained sounds.
