SCP-XXXX
The high pitched beep
Object Class: Keter
Special Containment Procedures: Due to the nature of SCP-XXXX a method of containment has not been developed. Any person who has encountered SCP-XXXX is to be put in a humanoid containment cell until further notice. Any recordings of the noise are labeled SCP-XXXX-2 and are to be safely stored in containment shelf 19-A6-XXXX-2
Description: SCP-XXXX is a high pitched tone, described as a half-second beep. The sound appears without any apparent warning or reason at random locations. Any person who hears the sound is labeled SCP-XXXX-1. People hearing the noise will experience confusion and nausea for approximately three seconds before returning it normal. About 55 hours after initial contact instances of SCP-XXXX-1 will begin hallucinating and will start making a beeping noise themselves. While SCP-XXXX-1's beep has no anomalous effects, it is very loud and can be distracting.(See Incident Report XXXX-A) SCP-XXXX was discovered on August 3rd, 2012 within Site 19. It was reported and heard by several researchers, but any search of the area came up negative. About two days later, at 10 PM, the researchers suddenly awoke and in their respective barracks and began emitting a loud beeping noise. After initial attempts to calm them security came and contained them. Looking at the logs it was declared that the beeping noise must have been, or been connected to some form of anomalous object. After two years several SCP-XXXX was detected 1 more time. (See incident report XXXX-A.)
Incident Report XXXX-A
The following is a record from an airplane blackbox and shows a pilot who was exposed to SCP-XXXX.
Pilot (SCP-XXXX-1): "(incoherent beeping noise)
Co-Pilot: "What?"
(Walking noises)
Assistant: "Could ya quiet down a bit, please?"
(Pilot flops out of his chair and continues beeping noises. The sound of hands hitting the control panel can be heard.)
Co-Pilot: "Ah shit! He turned off the autopilot!"
(A few muffled shouts come from the other parts for the plane.)
Co-Pilot: "Hold him down or something! I've got to drive this plane. (Yells in pain)!"
SCP-XXXX-1: (Thrashing, punches Co-Pilot's leg) Beep! Beep! Beep!
Assistant:"Stop! Stop thrashing!"
(Audible yelling intensifies from the back of the plane. It is now assumed that the plane is falling.)
All:"Aaaaaahhh!
(Explosions rock the plane and the black box cuts out.)
