SCP-1012: Secret Chord 


Item #: SCP-1012 
Object Class: Keter 


Special Containment Procedures: The Foundation has 
implemented protocols to cancel or to reduce the risk of generation 
of three of the five constituent sound tones that comprise SCP-1012: 


« Frequency B and Frequency D: Frequencies B' and D' are, 
respectively, the antiphases of Frequencies B and D. These 
antiphase frequencies cancel frequencies B and D, 
respectively, within the range of the broadcast. 


© The Foundation operates active noise cancellation 
broadcast devices in approximately 36,000 locations 
worldwide, commonly disguised as public address 
systems, klaxons, speakers and the like, which 
continually broadcast at Frequency B' or D' (subject to 
the availability of power). 

© Additionally, the Foundation has arranged for 
Frequencies B' and D' to be continually broadcast by 
most of the world's electroacoustic transducers. This 
has been achieved through a combination of inserting 
design changes into the engineering specifications of 
most commonly-manufactured electroacoustic 
transducers manufactured since 1988, inserting 
Frequency B', D' or both into the transmission of 
broadcast media and the encoding of recorded media 
(including inserting design changes into the engineering 
specifications of recording appliances so that Frequency 
B', D' or both are automatically encoded), and by 
manipulating the supply frequencies of commercially 
transmitted and distributed electric power so as to 
cause sound equipment and other electric appliances to 
generate Frequency B' or D'.1
