On this page, we track the strange sounds that are heard and recorded around the world. If you have or had any exposures to them, please inform us or post your experience on our facebook page (http://www.facebook.com/weirdsounds) with as much details as you can: Date, Time, Location, Description of sound, Anomalies associated with the sound, Length.
Also add a video or sound recording if you have one.
This is the best way to share the sound and see if others are hearing the same thing you are.
I think an electromagnetic processes in the ionosphere or, as less likely a natural geological phenomenon are able to create these sounds.
I’ve heard similar sounds in Belarus.
