Per 
SCP-XXXX
Object Class: Keter
Special Containment Procedures: Located at site 23 in ████ , Kentucky, SCP-XXXX must be isolated from every sound possible. SCP-XXXX is kept in an Iron sphere, approximately █ meters in diameter and ██ meters thick. The sphere must be internally padded with sound dampening materials; suspended 3 meters from the ground with the assistance of two ultra powerful Neodymium magnets. The magnets are approximately █ meters in size, █ meters thick. The magnets are centered and focused above and below the sphere in order to induce a "hovering" effect. (In the event of a containment breach: Protocol XXXX-M-X 001 will be followed.) Inside the containment chamber are eight speakers emitting varying nose canceling sound waves at a frequency of ███ to ███ hertz, at random intervals, in order to prevent SCP-XXXX from detecting sounds.
(Note: Constantly changing the frequencies prevents SCP-XXXX from filtering out the waves and detecting outside sound waves)
This SCP is highly dangerous and unpredictable. Only personnel with a security clearance of level 4 or higher may access this anomaly.
Personnel coming within 300 meters of SCP-XXXX's containment chamber MUST wear soft, baggy clothes that are especially loose fitting. Gloves WILL be worn at all times, and all clothing materials will be made from at least ██ percent cotton and ██ percent polyester. Clothing made from other materials are strictly prohibited from SCP-XXXX's containment area unless approved by at least four O-5 council members. The use of standard footwear is NOT permitted. In lieu of the above restriction appropriate, foundation approved, slippers (with the rubber souls removed) will be issued to anyone assigned or studying this anomaly.
Regular and traditional written speech is not permitted. Authorized communication will be: Nonverbal speech, written speech using a touch pad, and or text messages. Anyone that does not follow these procedures will be immediately terminated by strangulation via the jugular veins, or if time permits, lethal injection. .
Description: Found originally frozen in permafrost in ███ , Russia, SCP-XXXX was activated in response to the rise in global temperature. SCP-XXXX is a 1.5 meter creature with an ever-changing physical form, each form is unique to the person that has viewed it, though most who've seen the anomaly have described it as a humanoid creature with varying degrees of Piranha and Snake-like features. The only thing that remains constant are a pair of highly sensitive ear holes near, what would be on a human, it's neck. Whenever SCP-XXXX hears any type of sound it will immediately find the source of the sound and eliminate it by either destroying it, or in the case of living objects, forcefully removing the organs it uses to breathe.
Anyone that survives an attack from SCP-XXXX can request to be administered class A amnestics.
SCP-XXXX has extremely sensitive hearing. Its hearing range is millions of times better than the average humans and eclipses all known natural creatures on Earth. SCP-XXXX can hear between ████ nano hertz to ████ mega hertz making it one of the most dangerous anomalies that the Foundation's ever contained due to the measure to prevent the almost certain possibility that something will trigger it cause and SCP-XXXX to breach containment.
SCP-XXXX is extremely agile and highly durable, easily able to scale walls, jump ██ meters, and run on any solid or liquid surface at a minimum speed of ██ kph and a maximum speed of ██ kph for a distance of ██ km. The only thing that seems to cause it harm and or impede its destructive behavior is a special kind of chalk that is only found on the ██████ mountain range in ████, North Korea. Application of the chalk will cause SCP-XXXX to screech and go into a condition similar to severe anaphylactic shock, giving a MTF enough time to temporarily re-contain it with chalk dusted chains until it can be returned to its original containment chamber.
XXXX TEST A:
D-Class: (Typing) "Is this really necessary? We're a meter away from each other. Why can't we hold a normal conversation?"
Dr. ████ blankly stares at the D-Class with a look of irritation and puzzlement
Dr. ████ : (Typing) "We are just following protocol, D-261."
At this point the magnets used in containing the anomaly are turned off and with the use of a pulley system, specifically designed to be silent, SCP-XXXX's sphere is lowered to the ground without the D-Classes knowledge. The sphere opens
D-261 is startled after initially viewing SCP-XXXX, but regains his composure after realizing that the creature doesn't know he's there
D-261: (Franticly typing) "W-what the HELL is that?!"
Dr. ████ : (Typing) "Say hello to it. It's a Safe Class SCP"
D-261: (Typing) "You want me to say hi to that thing?! It looks like its two seconds from tearing me to pieces and you want me to say hi?! No fucking way!"
Dr. ████ : (Typing) "Okay, this test is over. You may leave the chamber."
As soon as the last message was sent Dr. ████ signaled to a MTF sniper to fire on D-261. It appears that 261 was struck in the shoulder and he let out a loud scream.
The scream activated XXXX and it proceeds to rip out the D-Classes trachea. 261 then proceeds to slump over and starts to choke before Protocol XXXX-M-X 001 was activated: flooding the room with the chalk powder until SCP-XXXX was incapacitated and re-contained. D-261 received medical treatment, but was pronounced dead an hour later due to blood loss.
All further testing has been postponed until further notice
