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.

Across history, people have reported unexplained noises echoing through the air, sea, and even underground. Scientists classify them as atmospheric, geological, or biological anomalies—while folklore often calls them omens or warnings.
This hub collects the latest cases, scientific research, famous recordings, and eyewitness reports of strange sounds worldwide. Whether it’s a sky trumpet in your city or an eerie hum at night, you’ll find explanations, theories, and ways to report your experience here.

- 🎺 Sky Trumpets — metallic groans & horn-like tones in the sky.
- 💥 Mystery Booms / Seneca Guns — sudden blasts felt/heard over wide areas.
- 🌀 The Hum — a low droning only a few percent can hear; worst at night.
- 🌊 Ocean Sounds — Bloop, Upsweep, Julia, Slow Down; hydrophone legends.
- 🪐 Space Sounds & Signals — pulsars, black holes, auroral “hiss.”
- 📻 Mysterious Broadcasts — numbers stations, UVB-76 “the Buzzer.”
- 🐙 Weird Animal Sounds — creepy and funny animals screams.
- 🎶 Sonic Wonders — natural accoustic oddities and sonic art.
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.
Most famous: Taos Hum, New Mexico, USA · Bristol Hum, UK · Windsor Hum, CA · Kokomo Hum, Indiana, USA · Auckland & Wellington Hums, NZ
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.

We should know what these trumpet sounds are , the Bible clearly tells us . If you have any doubt , I suggest you take the time and take note of what is occurring in the world today . And tell yourself ,to listen .
I heard what sounded like a trumpet resonating last night Thursday December 15th, 2022.
Lancaster Pennsylvania. Anyone else hear the noise recently?
My dad just heard the same noise as described above Saturday 22th at 2am In Morocco and he phoned me and told me and I have sent him one of the video and confirmed it , he also told me someone else heard it in the Northern part of Morocco . Saturday 22th at 2am same strange scary noise as dad described is recorded in Morocco 2022.
My opinion is it’s possibly a chainsaw, chipper, planer, or other power equipment besides the possible theories on this website.
