When I was in my room I kept hearing strange noises, i thought it was nothing the first time I heard it but it kept going on. Three hours later it is still going on and off. I think it's coming from the ground. I checked my radio, metal dectector, and other devices like that.

It sounds like a radio and some muffled talking combined. IT goes off about every five minutes. Please if you have any suggestions it's coming from around this one spot
