Strange Sounds: Mystery Booms, The Hum, Sky Trumpets, Ocean Bloop & Space Signals

Updated on: December 11, 2025

From apocalyptic sky trumpets to ocean “Bloop,” mystery booms, and the mind-bending Hum—this page is your master guide to the world’s creepiest unexplained sounds. Some are natural (meteors, ice quakes, whales). Others are human… or unknown.

Strange Sounds – Mystery Booms, Sky Trumpets, The Hum, Ocean Bloop & Weird Broadcasts — Illustration for the Strange Sounds hub: from sky trumpets to ocean bloops, mysterious broadcasts, and the Hum.

For more than a decade, Strange Sounds has followed the world’s weirdest noises — the unexplained booms that shake cities, the eerie sky trumpets that echo across continents, the low-frequency hum tormenting entire neighborhoods, and the deep-ocean bloops that still confuse scientists today. These sounds are part mystery, part science, part “what on Earth was that?”, and every year they generate new theories (and plenty of panic).

Strange sounds come from everywhere:

Atmospheric phenomena like skyquakes, meteor shockwaves, auroral crackling, and atmospheric ducting
Geological events such as earthquakes, icequakes, volcanoes, and subterranean pressure releases
Oceanic mysteries including unidentified deep-sea acoustics, seismic rumbles, and biological anomalies
Man-made sources like military tests, industrial harmonics, and infrastructure failures
And of course, the truly unexplained cases — The Hum, strange metallic horn blasts, repeating trumpet-like signals, and bizarre sonic events caught on video around the world

This hub brings all these phenomena together in one place. From our main sub-hubs — Mystery Booms, The Hum, Sky Trumpets, Space Sounds, Ocean Sounds, Weird Animal Noises, and other sonic oddities — you can dive into curated archives, scientific explanations, historical reports, and community eyewitness accounts. Whether you’re here to investigate, debunk, or just enjoy the weirdness of our noisy planet, this is your starting point.

If a sound in the sky ever made your hair stand on end — or if you’ve felt a vibration no one else hears — you’re in the right place. Welcome to the internet’s largest and strangest library of unexplained noises.

The Hum — The Sound That Drives People Mad

Imagine a diesel engine idling outside your bedroom at 3am—but only you can hear it. The Hum typically gets louder indoors, at night, and in quiet suburbs. A small share of people in “Hum zones” perceive it; many report headaches and insomnia.

Famous zones: Taos (US), Bristol (UK), Windsor (CA), Kokomo (US), Auckland & Wellington (NZ).
Theories: industrial low-frequency noise, geological micro-tremor, EM exposure, psychoacoustics—none universal.

Mystery Booms & Sky Trumpets

Metallic groans, horn-like blasts, and cannon-shot booms echoing across towns. Explanations range from quarry blasts and sonic booms to meteors, thunder, and atmospheric ducts. Others remain unexplained.

How to triage: check local quarry/blast schedules, MET/NOAA severe weather, flight paths, and meteor/fireball reports.
Sky trumpets: periodic viral recordings worldwide; some hoaxes, others genuine anomalies.

Strange Sounds from Space

Space is a vacuum, but telescopes “sonify” radio/plasma waves into audio. The results are chilling: pulsars (cosmic lighthouses), black-hole resonances, Jupiter/Saturn magnetospheres, and auroral “hiss.”

Strange Sounds from the Ocean

Hydrophones captured some of Earth’s loudest mysteries: the Bloop (1997), Julia (1999), Upsweep (seasonal since 1991), and Slow Down (Antarctica). Many correlate with ice events; some remain enigmatic.

Weird Animal Sounds & Sonic Wonders

Animals: pistol shrimp “gunshot,” whales/elephants infrasound, koalas’ guttural calls, lyrebird mimicry.
Sonic wonders: singing sand dunes, ringing stones, wind-driven sculptures (e.g., Singing Ringing Tree).

Strange Sounds — FAQs

What is “The Hum”?: The Hum is a persistent low-frequency droning sound that only a small percentage of people can hear. It is often stronger indoors and at night, and has been reported in Taos (US), Bristol (UK), Windsor (CA), and more. No single cause explains all cases, though theories include industrial noise, geological tremors, and electromagnetic exposure.
What causes mystery booms?: Mystery booms may come from thunder, quarry and mining blasts, sonic booms from aircraft, meteors (bolides), or shockwaves ducted by temperature inversions. Some remain completely unexplained, despite centuries of reports, and are often linked to folklore like “ghost cannons.”
Can animals sense strange sounds first?: Yes. Many animals perceive infrasound and electromagnetic shifts far below human hearing. Dogs, birds, elephants, and marine mammals often react seconds to minutes before humans notice booms, quakes, or sky trumpets.
Do we really hear sounds from space?: Not directly. Space is a vacuum, but radio and plasma waves can be converted into audio by scientists (“sonification”). Pulsars tick like clocks, black-hole regions rumble, and auroras hiss when translated into sound waves.
What should I do if I hear a strange sound?: First, record it on your phone. Then note the exact time, location, and weather conditions. Check local blast schedules, severe weather reports, and meteor/fireball data. Finally, send us a report so your case can be compared with others worldwide.
