SCP-XXXX: Echo
Item #: SCP-XXXX
Object Class: Euclid
Special Containment Procedures: Item SCP-XXXX is to be contained in a small glass container. All instances of glass should be reinforced and soundproof, and glass walls should be at least 2.5 cm thick. Container should be placed at the center of a large, empty room. All video cameras located in this room should be silenced. Any other objects capable of producing sound are prohibited in SCP-XXXX's containment area unless authorized by a Level 4 personnel. In addition, a vast, reinforced secondary room should be created adjacent to the original in case of a transformation incident. The secondary room should contain a speaker which, when enabled, periodically projects a loud noise into the air. This room is denoted as the Quarantine Room.
While inside of SCP-XXXX's chamber, at least two personnel must be monitoring each other. All personnel must be acutely aware of each other and the object's location at all times.
If a transformation occurs, the object or being should be held inside of the Quarantine Room. If SCP-XXXX transforms into another anomaly of Euclid or higher rating, SCP-XXXX should be contained alongside the anomaly it has targeted. From there, further instructions can be authorized by the Site Director. If two identical objects are discovered, both objects are to be treated as SCP-XXXX, and both must be placed in the Quarantine Room until SCP-XXXX is revealed.
Any object obscuring the path of SCP-XXXX during transformation will instantaneously disappear if and when it comes into contact with the transforming body of SCP-XXXX. No physical attempt to stop the transformation process should be made. The only known way to stop the transformation process is to terminate SCP-XXXX's target. At this time, there is no known way to contain SCP-XXXX while it is transforming; it must be contained either before or after the transformation process. There is no known way to pause the transformation process.
Description: In base form, SCP-XXXX is a large diaphragm condenser microphone, standing at approximately 20 cm in height, and is made entirely of frosted glass. When isolated, the object is completely idle and for all intents and purposes, inanimate. SCP-XXXX's effects occur when a sound enters the microphone at a volume of 35dB or greater.
SCP-XXXX is capable of mimicking the shape, size, and outwards appearance of all items from which it receives auditory stimuli, both animate and inanimate. Once the transformation has begun it will become a perfect white in color, reach completion in three to five seconds, regardless of the relative size of it's target, and cannot be stopped by any known means. These transformations have a set time constraint that prevent them from being executed again. Times will vary based on the complexity of the form it takes, but SCP-XXXX can transform while transformed into another object, as long as the set time constraint has been reached.
Once the transformation has completed, SCP-XXXX becomes completely indistinguishable from the original target. After transformation, SCP-XXXX has the potential to gain sentience, but only if the original target possessed sentience. SCP-XXXX gains all thought processes, memories, behaviors, and mannerisms of the target. When questioned, SCP-XXXX does not recognize itself as SCP-XXXX. The target does not have to be within range of sight; however, if the source of the auditory stimuli is terminated, the object will return to its base form.
If multiple sounds are received by SCP-XXXX at the same time, the object will become the source which emits the loudest auditory stimuli. If presented with two identical stimuli, the object will become the source which is the closest; if all sources are identical and equidistant from SCP-XXXX, the object will consistently transform into the same source unless moved again.
SCP-XXXX was originally discovered during a police investigation in ████████, Ohio. Caleb ███████ claimed over the phone to have been followed home and stalked by someone. A policeman was then sent to monitor Caleb. While Caleb and the policeman were supposedly out, however, Caleb called the police station and reported that he had seen himself and another policeman outside of his own home. The man reported to be standing outside of his own home at the time of the incident.
Another officer was dispatched to the supposed location of the second Caleb while the original was monitored. Upon attempt to communicate with Caleb, however, the effects of SCP-XXXX occurred, resulting in the police officer coming face to face with a duplicate copy of himself. SCP-XXXX was then taken into custody after a fight between the two officers. A few hours after SCP-XXXX was taken into custody, it disappeared. Video evidence later revealed that SCP-XXXX escaped in the form of a rat.
Upon hearing of this incident, Foundation personnel were dispatched to the location. SCP-XXXX was discovered 62 hours later in the form of a rake. The rake was taken by Foundation personnel and isolated until containment procedures were developed. All individuals in the incident who were not directly related to the Foundation were administered Class-A amnestics.
Addendum: Test Logs
All tests listed are conducted in a hours:minutes:seconds:milliseconds format, with the bright light signaling the start and stop of the experiment. All objects produce either constant sound or produce sound as often as possible. Objects are sorted from least time to most. Objects are tested multiple times and consistent within a 1 second time frame; times are an average.

File contains recorded video interactions between speakers designated A and B, being tested in conjunction with SCP-XXXX. A third Speaker plays static noise at a volume of 35dB, designated to act as a target after SCP-XXXX's transformation. 2 Level 3 personnel handle movement of speakers and are instructed to remain silent. Observed and monitored by Senior Researcher Mohlenhoff.
<Begin Log | 02/11/20█7, 7:50 AM>
Speaker A is placed in the room with SCP-XXXX. Upon playing a beep, SCP-XXXX becomes a duplicate copy of Speaker A for 3.24 seconds before turning into ambient Speaker C.
Speaker B is placed in the room with SCP-XXXX. Upon playing loud music, SCP-XXXX becomes a duplicate copy of Speaker B for 3.54 seconds.
Speaker B plays recorded sounds of a dog barking. SCP-XXXX becomes a duplicate copy of Speaker B for 3.44 seconds.
Another copy of Speaker A is introduced into the room, closer to SCP-XXXX, with A1 written on it. Speakers A and A1 play a beep; SCP-XXXX becomes a duplicate copy of Speaker A1 for 3.28 seconds.
All speakers are moved equidistant from SCP-XXXX. Speakers A and A1 play a beep; Speaker B plays loud music. SCP-XXXX becomes a duplicate copy of Speaker B for 3.52 seconds.
Previous test is done, except Speaker B remains silent. SCP-XXXX becomes a duplicate copy of Speaker A1. This is tested multiple times; SCP-XXXX consistently transforms into Speaker A1 despite receiving two equidistant sounds.
All speaker tests are complete. Ending log.

Mohlenhoff begins tests by shaking a bag of candy near SCP-XXXX. SCP-XXXX becomes a duplicate copy of the bag of candy, identical in every way.
Mohlenhoff opens the bag of candy. SCP-XXXX becomes a duplicate copy of the now opened bag of candy. Contents are exactly the same in both bags.
Mohlenhoff drops a candy near SCP-XXXX. SCP-XXXX becomes a duplicate copy of the exact candy Mohlenhoff dropped.
Mohlenhoff shakes the empty bag. SCP-XXXX becomes a duplicate copy of the empty bag.
All candy tests are complete. Ending log.

Frog and flies are introduced into SCP-XXXX.
Frog gets distracted by flies and follows flies. SCP-XXXX transforms into a fly.
SCP-XXXX has been lost in the crowd of flies. Frog has approached SCP-XXXX's initial location.
Frog croaks after eating multiple flies; SCP-XXXX becomes a duplicate copy of the frog from inside of the frog's stomach. Frog disappears during transformation and SCP-XXXX immediately transforms back into base state. Ending log due to disappearance of initial frog. Consumption of SCP-XXXX is not recommended.

File contains recorded video interactions between SCP-XXXX and D-Class personnel 1450. D-1450 has been instructed to communicate with SCP-XXXX. Observed and monitored by Senior Researcher Mohlenhoff.
<Begin Log | 02/13/20█7, 8:50 AM>
D-1450: I'm supposed to speak to a microphone?
SCP-XXXX becomes a duplicate copy of D-1450. D-1450 immediately exhibits concern.
D-1450: What the hell? What are you?
SCP-XXXX: What do you mean? Wait, are you a mirror?
D-1450: No, all I know is that I was instructed to speak with you.
SCP-XXXX: This must be some sort of trick, because I was instructed to speak with the… whatever-it-is inside this chamber. Clearly that isn't me, so it must be you.
D-1450: What do you mean, "that isn't me"? You're a freak. Moments ago you were a microphone sitting in the middle of the room.
SCP-XXXX: No, you were the microphone. I just saw you, moments ago. Like you said.
Both D-1450 and SCP-XXXX exhibit extreme, yet similar confusion. SCP-XXXX exhibits no acknowledgement of being an anomaly. Senior Researcher Mohlenhoff enters the room to calm them down.
Mohlenhoff: Don't worry, you two, this transformation is expected. I'm now going to ask one of you to stay here, and one of you to leave to the separate Quarantine Room in the facility for a few hours.
SCP-XXXX: Why? Is something wrong?
D-1450: I'm confused, why am I being contained?
Mohlenhoff: Don't panic. I promise both of you, this will be resolved in a few hours.
Both eventually comply and are separated. After 3 hours, 11 minutes, and 55.68 seconds, SCP-XXXX transforms into the static speaker inside the Quarantine Room. D-1450 is removed from SCP-XXXX's containment area. Ending log.

File contains recorded video interactions between SCP-999, SCP-XXXX, and D-Class personnel 1482. Observed and monitored by Senior Researcher Mohlenhoff.
<Begin Log | 02/14/20█7, 7:50 AM>
SCP-XXXX and its glass container have been placed in the chamber with SCP-999. Action should begin once SCP-999 opens the glass container.
SCP-999 has opened SCP-XXXX's glass container and SCP-XXXX has taken the form of SCP-999. Very shortly after introduction, both SCP-999 and SCP-XXXX have started a tickle fight. Both beings exhibit extreme happiness during this process, even more so than SCP-999 usually presents on its own. Both are identical as orange slimes, roughly the size of beanbag chairs.
Shortly after, D-1482 is led into the testing room, assured that all creatures inside are harmless.
SCP-XXXX and SCP-999 have now taken interest in D-1482 and are tickling him intensely. He appears to be in a state of pure euphoria as both anomalies relentlessly tickle him. No words are coming from D-1482, only laughter.
Ending session; D-1482 has passed out from too much laughter. SCP-XXXX and SCP-999 are being placed in the Quarantine Room.
<End Log | 02/14/20█7, 9:20 AM>
After the tickle incident, D-1482 exhibits depression. This effect does not occur when exposing a D-Class patient to only a singular instance of SCP-999. Exposure to SCP-999 has been attempted but only acts as a temporarily relief. Short video interview attached.
<Begin Log | 02/14/20█7, 9:30 PM>
Mohlenhoff: Are you alright, D-1482?
D-1482 refuses to look up. A few more questions are asked, until one finally triggers a response.
Mohlenhoff: Were you dissatisfied with SCP-999 and SCP-XXXX?
D-1482: …No. I was completely satisfied. I think that's my fucking problem. You assholes exposed me to pure happiness, something pure and unbelievable. It was bliss. But as far as I can tell, I'm here to be tested upon, not to be sympathized. Leave me alone; it's your fault I feel like this.
D-1482 buries his head into his arms. Subject refuses to answer any questions past this point. All attempts to reconcile D-1482 permanently have failed.
