2. 32 Class D test subjects were able to perceive at least partial 
anomalies in multiple songs, but not in all songs. 

3. 2 Level 1 test subjects and 22 Class D test subjects were able to 
perceive at least partial lyrical anomalies in all songs. 

4. A single Level 1 test subject and 1 Class D test subject were 
unable to perceive the anomalies associated with SCP-1398-1 
playback and instead heard it as an unremarkable aloum. Coupled 
with the data garnered at initial recovery, the number of confirmed 
individuals unable to perceive SCP-1398-1's lyrical anomalies totals 
at 6. 


Addendum 1398-01a: [REDACTED] 


Addendum 1398-01b: SCP-1398-1-6's overall content is difficult to 
determine at present. Transcribed portions contain an unspecified 
narrator discussing one or more unnamed entities. Lyrical anomalies 
thus far recorded consist of only two stanzas; "He waits with a heavy 
heart, for his progeny he grieves,/ Each day more return to him, yet 
even more go deceived! Long shall be his reign, when he comes 
again/ Look well for his signs and know, when his blood will flow/", 
which replaces the fifth stanza, and "Rejoice he is waiting arms held 
open wide/ Each and all shall sing his blood, those that seek or you 
who hide/ Approach drink of his love, he won't be denied, he'll come/ 
Life and breath, flesh and bone, he'll come and take his children 
home’", which replaces the seventh (final) stanza. 


What is notable about SCP-1398-1-6 is its additional effect on 
perceptive test subjects; listeners become markedly more agitated 
during playback of SCP-1398-1-6, with most immediately requesting 
cessation of playback. In 27 test subjects this agitation was acute, 
requiring restraint of subject and, in 16 cases, culminating in 
syncope. In these acute cases subjects appear to experience 
hallucinations; reacting to objects/actors that are not present and 
appearing oblivious to the presence of research personnel. The 
precise nature of these episodes is difficult to ascertain, as test 
subjects are invariably uncooperative during playback and unable to 


recall having any hallucinations or hearing any lyrical anomalies 
afterwards. 


Subsequently, those displaying acute reactions to SCP-1398-1-6's 
anomalies consistently develop progressive cases of thanatophobia 
post-test. At the outset subjects avoid items or activities which could 
reasonably cause harm, but increasingly overestimate any possible 
danger posed to their person. A single affected Class D personnel 
allowed to continue 160 days past scheduled termination eventually 
refused to consume any solid food for fear of asphyxiation and 
reacted hysterically to all requests that he leave his cell. 


Addendum 1398-02: Limited testing of civilian subjects has been 
approved by and carried out at University under the guise 
of an "Auditory Memory Study." Subjects each limited to a single 
listening session, with playback of SCP-1398-1-1 and SCP-1398-1-6 
withheld. Out of 167 test subjects, only 3 were able to perceive 
anomalies during SCP-1398-1 playback. No additional lyrical 
anomalies were recorded. For full test data and transcription records 
please see TD.1398.17

SCP-1399: Another Way of Hearing 


Item #: SCP-1399 
Object Class: Safe 


Special Containment Procedures: SCP-1399 is to be kept ona 
plain wooden desk in the middle of a locked room, open to the last 
page, with a camera observing it at all times. If the page is observed 
to change in any way, notify the Site Administrator. 


Additionally, an adjacent room, henceforth designated as the 
observation room, is to be set up with a television and radio set to 
switch between several news channels on an eight hour cycle. 


Description: SCP-1399 is a thin fifteen page children’s book titled 
“Another Way of Hearing.” The cover depicts the earth, with the title 
above it. There is no author indicated on the cover. SCP-1399’s 
ISBN correlates to no assigned ISBN, and its labeled publisher, 
Detiskia Books, corresponds to no recognized publishing company. 


When read sequentially, one page at a time in its entirety, it consists 
of a variety of disconnected visual images that have strongly 
associated auditory connections, along with the words “Another Way 
of Hearing [Image]”. Page three, for instance, is an image of a train, 
below which are the words “Another Way of Hearing Trains.” Save 
for the last page, all images and text have remained static while in 
Foundation hands. 


The anomalous effect of the book occurs once the last page is 
turned and the book is closed. Immediately, the reader ceases to be 
able to receive any auditory stimuli from the world around them. 
Instead, their eardrums will resonate in concert to what has been 
determined as the auditory stimuli of a variety of alternate worlds. 
That is, their hearing will be transposed to another reality. This 
phenomena extends only to hearing, with sight, touch, taste, smell, 
and less conventional senses apparently unaffected. 


It has been determined that the particular alternate universe to 
which the book attunes its reader is dependent on the last page, 
which changes periodically. All readers who experience the effect 
between changes have been determined to be hearing the same 
world. A list of recorded historical diversions and related images can 
be found in Document-1399B. 


The last page so far has appeared to change at the same time as a 
variety of major world-altering events occur. The book seems to re- 
attune people’s hearing to a world where that event occurred 
differently, usually in a catastrophically negative way. 


This phenomenon has been noted to create considerable distress 
among D-class personnel due to disorientation from a difference in 
auditory and visual stimuli. For this reason it is advised to provide 
any affected personnel with a pair of high-quality earplugs to assist 
with concentration during interviews and in the interest of preserving 
their sanity. D-class personnel subjected to the effects of SCP-1399 
are exempt from monthly terminations until all possible acoustic 
mapping of the particular alternate reality has been completed. 


Document-1399A 


Page Change Procedure 

If at any time, the last page of SCP-1399 is observed to 
change, three D-class personnel are to be recruited ona 
voluntary basis; due to their subsequent removal from 
monthly terminations, volunteers have proved relatively 
easy to find. To prevent complications, personnel are to 
be briefed of the effects of SCP-1399 before exposure. 
Once subjected to SCP-1399, the first D-class is to be 
escorted to the previously established observation room. 
The D-class is to be provided with a writing utensil and 
paper for them to record all possibly relevant information 
pertaining to the divergence. After eight hours, conduct a 
written interview and rotate in the second D-class. 
Continue process every eight hours until all possible 
information has been collected.

Israel's Mossad is implicated. Yemen declares 
war on Israel. Yemeni officials acquire nuclear 
weapons through undetermined channels and 
utilize them; nearly all of Israel destroyed or 
contaminated in resulting 15 Mt explosion. A 
chain of retaliations takes place over a period 
of twelve hours, resulting in nuclear holocaust 
and presumed destruction of Foundation 
facility. D-class subjects suffered complete 
hearing loss due to incineration of eardrums in 
both ears.

Articles 1400-1499 


SCP-1400: Sirens 


Item #: SCP-1400 
Object Class: Euclid 


Special Containment Procedures: SCP-1400 is to be kept in an 
individual soundproofed cell adjacent to a standard humanoid 
containment suite, which is to contain the current SCP-1400-A. This 
cell and suite are to be located in the geometric center of a 55 x 55 x 
10 m containment cell. No microphones or audio recorders of any 
kind are to be installed in any of these cells. Cameras are installed 
in each corner of SCP-1400's containment cell in order to track the 
direction in which its head is facing. In the event that SCP-1400 
faces any direction other than towards the current SCP-1400-A, 
monitoring personnel are to note the new direction immediately and 
dispatch a mobile task force in that direction to identify and capture 
the new SCP-1400-A. The previous SCP-1400-A may be disposed 
of as per normal Foundation protocols. 


As SCP-1400 does not require sustenance, no personnel are to 
enter its cell except during Site-wide emergencies. To this end, the 
door to its cell is to be secured by a keycard lock accessible only by 
the Level 4 supervisor overseeing SCP-1400. In the unlikely event 
that entry to SCP-1400's cell is required, all personnel involved must 
wear earplugs and noise-cancelling headphones. Should any 
personnel display an unusual degree of interest in touching 
SCP-1400, they are to be immediately removed from SCP-1400's 
presence and administered Class-G short-term amnestics in order to 
mitigate SCP-1400's effect. 


Description: SCP-1400 is a humanoid Caucasian male of 
indeterminate age and average build, nude except for a black FM50 
gas mask with opaque smoked lenses. It is wholly intangible to all 
human beings except its current instance of SCP-1400-A. The entity 
speaks constantly, although its vocalizations are always muffled by 
its mask to the point of indecipherability. Although apparently 


capable of normal locomotion, it tends instead to move by a poorly- 
characterized form of instantaneous translocation. The range of this 
movement is restricted to a radius of approximately 50 m 
surrounding SCP-1400-A. 


SCP-1400's voluntary activities consist entirely, so far as can be 
inferred, of observation. It selects a target, designated SCP-1400-A, 
which is invariably a human Caucasian male of similar build and 
appearance to SCP-1400.1 Selection may be inferred by 
SCP-1400's movement: upon selecting SCP-1400-A, it takes up a 
position within 20 m of this target and begins to watch it. Though the 
position of its eyes cannot be observed through its mask, the 
motions of its head track SCP-1400-A's movements quite closely. It 
follows its target’s movements regardless of line of sight: barriers up 
to and including 5-cm lead plating do not impede accurate tracking. 


Although SCP-1400 attempts to hide from its target, it does so 
ineffectively: SCP-1400-A typically discovers it within one week of 
selection. Subject reactions vary, although most tend towards fear 
and distrust, as is typical for persons confronted with the reality of 
constant surveillance. In the medium to long term, most instances of 
SCP-1400-A develop paranoid tendencies. Again, this is 
psychologically typical. The only anomalous component of 
SCP-1400-A's behavior is an extreme and universal revulsion at the 
idea of seeing SCP-1400’s face. 


SCP-1400’s vocalizations are an active cognitohazard. 
Approximately 75% of persons exposed to these sounds report a 
strong desire to remove SCP-1400’s mask and are designated 
SCP-1400-B. Stated reasons vary with the listeners' personality and 
motives: some claim to want to hear its words clearly, some to want 
to prevent it from suffocating inside the mask, some to want revenge 
on it for frightening them, etc.2 SCP-1400-A is immune to this 
cognitohazard by virtue of being completely selectively deaf to the 
vocalizations. 


Interestingly, SCP-1400-A is also the only human being capable of 
making physical contact with SCP-1400. When an instance of 
SCP-1400-B discovers this fact, it invariably attempts to make 
SCP-1400-A remove SCP-1400's mask. These attempts scale 
quickly from polite persuasion to threats of violence, eventually 


culminating in physical altercations. SCP-1400-A will resist removing 
the mask by all means available; instances have repeatedly been 
killed by groups of SCP-1400-B without removing the mask. The 
current SCP-1400-A has withstood all means of non-anomalous 
enhanced interrogation available to the Foundation and still refuses 
to interact with SCP-1400, even for testing. 


Incident 1400-Cumberland: On / /_, in order to study the social 
dynamics of groups of SCP-1400-B in the absence of SCP-1400-A, 
25 Class-D personnel were introduced into SCP-1400's containment 
cell. At 1 hour 17 minutes into the experiment, SCP-1400 suddenly 
redirected its attention to one of the subjects. The other instances of 
SCP-1400-B immediately surrounded and subdued the new 
instance of SCP-1400-A and forced his hands to lift the mask. 
Several instances of SCP-1400-B had unintentionally interposed 
themselves between the monitoring cameras and the front of 
SCP-1400's head, so there is no visual record of its unmasked face. 
However, all members of SCP-1400-B who saw its face immediately 
recoiled. Once SCP-1400's mask was completely removed, the 
entity rapidly melted into a dark liquid consisting of water adulterated 
with large amounts of heavy metals, phosphates, and human waste. 
Simultaneously, SCP-1400-A put on the mask and translocated out 
of his clothes in the same manner as SCP-1400, appearing on the 
other side of the outer containment chamber. He is now designated 
SCP-1400-1. 


Addendum 1: Recent unconfirmed reports suggest the existence of 
other entities resembling SCP-1400. All are described as humanoid 
figures, nude except for a mask that is opaque over the face and 
eyes. The instances thus far described have been provisionally 
designated as follows: 


* SCP-1400-2: an obese African male with heavy keloid 
scarring on the forearms, wearing a Guy Fawkes mask 

* SCP-1400-3: an elderly Asian female, wearing a medieval 
Crusader's helmet 

¢ SCP-1400-4: an underweight male Pacific Islander with 
extensive ta moko tattoos, wearing the head of a Chinese 
parade lion 

* SCP-1400-5: a male Latino with large breast implants, 


wearing the helmet of an Apollo Block | A1C space suit
