Electronic Voice Phenomena(EVP)is the recording of sounds or voices that have no logical source. EVPs can be recorded almost anywhere and especially in areas that are known as haunted. This can be done with any ordinary recording device such as a hand-held tape recorder for example. While recording, one will usually not hear anything. Upon play-back one might hear an unexplained noise or disembodied voice. It is crucial that one write down or note any voices or sounds made by themselves or people in the environment.Below  is the collection of EVPs we recorded during our investigations. Anyone can do this, do you dare try? It is a scientific fact that this happens, mankind has known this since Thomas Edison. 
The following EVPs were recorded at the abandoned youth center Oak Hill near Laurel, MD.
