Across the country, entire communities have been reporting that strange, unidentifiable sounds have been heard in and around their areas.

These various sounds appear to fall into two categories: living and non-living. Though the two categories of sounds appear to be unrelated, the reports keep rolling in.

The living sounds appear to be originating from the ground-level and are often blamed creatures not yet known to science; such as Sasquatch, alien beings, or something else.

The non-living sounds appear to come from the sky and are contributed to UFOs, solar flares, and even the mysterious skyquakes. Below is a list of the most recent reports of mysterious sounds that fall into each category.

Incidents Around the World

Umatilla Reservation

Recently, TSW reported on the bone chilling screams heard in and around the Umatilla Reservation during the night. Locals and experts are at odds as to the sound's origin, but can agree that it seems to be biologic.

Many who have heard the sound believe it is either a female or adolescent Sasquatch. On the other hand, many wildlife experts contend that these are the late night calls of foxes and/or barn owls.

Canadian Howls

Similarly, The Huffington Post recently reported on strange howls being heard day and night throughout Canada.

The sounds fill the air and in the video clip appear to startle birds and cause dogs to bark. The thunderous howls are so loud that some witnesses even claimed to have been woken up by the noise.

Theories abound as to what the howls could be; contributing them, once again, to Bigfoot or even aliens. Several people even brought up the idea of dragons or some other creature unrecognized by science.

Experts have not officially weighed in one these sounds, but tend to lean away from something biologic and more towards something geologic or even mechanical.

Skyquakes

However, the sounds being investigated by Mysterious Universe have been ruled out as being biologic altogether. The sounds are described as explosions, sonic booms, and even tonal in nature.

Unlike the previous two sounds, these sounds appear to originate from the sky, causing many witnesses to call these strange noises "Skyquakes".

Nevertheless, the so-called skyquakes have yet to be identified as originating from any known natural causes. Some witnesses claimed to have heard the sounds right before or right after UFO sightings.

However, many researchers dismiss this theory and contend that if the videos and eyewitness accounts are not actually hoaxes, that it is more than likely that the sounds are the result of something geologic.

Result of Solar Flares?

Yet, the debate rages on because Elchin Khalilov told the GeoChange Journal that his research seems to indicate that the sounds actually originated from space.

His conclusion was that the sounds were the result of "solar flares and huge energy flows generated by them, rushing towards Earth's surface and destabilizing the magnetosphere, ionosphere and upper atmosphere". However, no one else has substantiated Khalilov's claims.

What Is Causing the Sounds?

What are these sounds?

Where do they come from?

Are they all related somehow?

Or, does each individual mysterious sound have its own answer?

Is the entire idea of the mysterious sound phenomenon nothing more than an elaborate hoax?

No one really has the answers to any of these questions. Furthermore, the theories that some are willing to provide are quickly contested by those who have claimed to have heard the sounds.

The entire phenomenon appears to be a hotly debated subject. In the References section below, you'll find links to hear the various sounds for yourself.
