It is interesting is it not?? --- that the announcer for the Tropicana game talked about this strange sound as "haunting," - then he says:  "SOMEBODY SHUT THE DOOR!"  What IF that strange sound is the door OPENING IN HEAVEN in preparation for the RAPTURE and once it is SHUT (as this announcer cries out), no one will be able to OPEN it again!!! This could very well be the sound of a HUGE (VERY HUGE!) door opening in heaven!
