Audio Transcript of Test 4647-1-B;
After test 4647-1-A, D-025 is selected to enter the containment chamber after D-052 in order to test human response to SCP-4647. D-025 has been equipped with measurement and observation gear, as well as radio equipment and noise-canceling headphones.
Observation: "25. You can hear me correct? Confirm now."
D-025: "I can hear you."
Observation: "25, approach the radio."
At this point, a sound is emitted that cannot be detected by Observation's sensors.
D-025: "Alright."
D-025: "Are you hearing this?"
Observation: "25, attempt to turn off the radio. Do this now."
D-025: "These earplugs don't work. I can hear it clearly." (Note: D-025's headgear had been later found to have sustained a mechanical malfunction, compromising the noise-canceling capabilities.)
Observation: "It is fine. Attempt to turn it off, you are in no harm."
D-025: "…nothing."
D-025: "He's talking to me."
Observation: "Repeat what 'he' is saying to you."
D-025: "He's always watching me."
Observation: "Can you see him? Describe him, describe his voice."
At this point, D-025 begins to look around the room, as in an apparently worried state. Observation's medical staff reports an increase in heart rate.
D-025: "…it's deep, a bit contorted. It's slow. It's always the same exact phrase."
Observation: "How do you feel?"
D-025: "I can hear it perfectly even with the muffs on."
D-025: "I feel uneasy. It feels like he's talking straight to me, not a recording."
D-025 grabs SCP-4647, attempting to look for buttons. Upon finding the controls SCP-4647 has, he attempts to change settings of SCP-4647 to no effect.
D-025: "I need to hear it better, hold on."
D-025 takes off his headphones, placing them on to the container.
Observation: "Alright. I'm going to ask you to take ahold of mice's cage. Do this now."
D-025: "I can hear it clearly now."
D-025 moves his head closer to SCP-4647.
D-025: "…yes."
Observation: "Have you heard anything else from this man?"
D-025: "He told me he's here, that's all I need to know."
Observation: "Alright. Move to the door behind you. You'll be retrieved soon."
Observation's medical staff report a return to normal heart rate, but the of D-025 bodily language remains constant within a fearful state.
D-025: "Are you watching me?"
Observation: "25, check the radio for any sort of insertion tray. Where you might put a disc perhaps."
D-025 drops SCP-4647 in an erratic manner. He backs up from the container, grabbing the earmuffs, and receding into a corner.
D-025: "I saw him, he's coming."
Observation's medical staff report D-025 is on a receding verge towards a cardiac arrest. D-025 then proceeds to move towards the windows, eyes bloodshot. D-025 appears to be screaming.
D-025: "GET ME THE [EXPLETIVE] OUT OF HERE! NOW!"
Observation: "Move to the doors and you'll be removed. Do this now, 25."
Observation: "Remain calm."
D-025 continues to bang his fists on the window, in panic.
Observation: "I repeat 25. Move to the doors now."
D-025: "HE's HERE! GET ME OUT!"
D-025 runs to SCP-4647 and proceeds to grab it.
D-025: "SHUT THE [EXPLETIVE] UP!"
D-025 begins speaking in a delirious, "insane" tone before collapsing on the floor, going unconscious.
Security personnel enter to remove D-025 and place D-025 in quarantine.
Post-test Action Report
After test 4647-1-B, D-025 awoke in quarantine upon which D-025 immediately begin inflicting injuries upon himself, aiming to [REDACTED]. These injuries later resulted in suicide by blood loss. Upon further recollection of the incident, observational staff recommended adding blind-folding as a part of the testing procedure to prevent suicidal tendencies post-test.
