An example of a speaker horn that SCP-XXXX can access and manipulate.

Item #: XXXX

Object Class: Keter

Containment Procedure: SCP-XXXX is to be kept in Heavy Confinement, in a cell with the diameters 5m x 5m x 5m. The walls of the cell are to be 3m thick and fully soundproof, and have three (3) fully operational containment gates leading to the cell's entrance. Under no circumstances shall any personnel enter the cell or open any of it's containment gates without anything less than five (5) O5 Council votes, and all research is strictly forbidden. All other information regarding SCP-XXXX's containment has been [DATA REDACTED] by O5-██.

Description: There is no known knowledge of SCP-XXXX's visual appearance, if it has any. The only information our scientists have gathered through the few experiments authorized is that SCP-XXXX is a wave of sound constantly fluctuating between sources of sound such as human speech, audio equipment, and electronic devices with sound emitting capabilities. SCP-XXXX, when active, typically causes static sounds and "sings" or hymns nursery rhymes such as Twinkle Twinkle Little Star, Ring Around the Rosie, or [DATA EXPUNGED]. The sound it emits has been described by D-class test subjects as severely tormenting, to the point of crippling their very movement. Continued research of SCP-XXXX has been strictly forbidden due to a severely threatening breach, see Addendum-03.



Addendum-03: During one of SCP-XXXX's tests, SCP-XXXX breached containment due to the failed knowledge of SCP-XXXX traveling through one of the D-class subjects after he started screaming from what he described as painfully static audio SCP-XXXX played during his test after SCP-XXXX sung an unknown rhyme about [DATA EXPUNGED]. SCP-XXXX's breach caused a chain reaction of sound and static throughout the testing area, critically damaging the hearing of both researchers and most of the guards within the vicinity of the testing chamber. SCP-XXXX's breach caused a global Heavy Containment lock-down in which all staff in the vicinity were to deactivate any and all sound equipment outside SCP cells, and were to keep calm and quite until given further instructions. However, when SCP-XXXX traveled through one of the guards, the guard went running off into SCP-XXXX's cell in which researcher █████ shut SCP-XXXX containment gates, trapping the guard inside along with the SCP. No one knows what happened to the guard, however SCP-XXXX was given immediate restriction to any kinds of access and future containment methods are in place for any further possible breach attempts.
