It is unknown why this happens, further research is being conducted.
SCP-3631 gives off an extremely high frequency that causes severe harm to the eardrums of those who hear it, but in most cases it results in the deafening of the listener.

SCP-3631's frequency has a different encryption depending on its diet, however the most unusual translation is a single word, Nevermore.
