In the basement in 1 of the rooms in this house i keep hearing this thumping sound. I thought it was music from outside but i heard nothing around the house, i don't think the pipes can make this noise. It sounds like music inside someones house but all you hear is a faint beat. It also sounds like someone knocking on the walls but i am not going that route. ANy idea what the sound could be? i can't hear it anywhere else in the house but that 1 room. It is the same beat for the past 30 minutes....it is kinda freaking me out because i have no idea wtf it is....
