The Unknown Zone: The Ping and other strange noises around the world.

A mysterious "pinging" noise is emanating from the seafloor in one of Canada's northernmost territories, and officials have yet to identify the source.

The sound has been heard in recent months in the Fury and Hecla Strait, a channel of water in the Nunavut region of Canada. The Canadian Department of National Defence was informed of the strange noises and investigated the ping's origin, to no avail, reported the CBC.

At the same time A mysterious noise from the sky is continuing to baffle people all over the world - as well as giving those who hear it sleepless nights.

Sounding like a trumpet or a collective from a brass section of an orchestra, a selection of videos shot from the Canada to Ukraine, via the U.S., Germany and Belarus show strange goings on above us.

And the eerie sounds have been continuously heard at all different times and locations for almost a decade. 

Judy Sellins and Dave Turco of the Unknown Zone will bring you the possible explanations and updates.
