Auditory pareidolia is a phenomenon in which people can hear familiar sounds from seemingly static background noise.

The phenomenon of hearing intelligible voices or noises in meaningless background noise is known as “auditory pareidolia.” The sources of this noise vary; they may include electric fans; running water; airplane engines; the hums of washing machines; or white-noise machines, according to audiologists. It is an auditory sub-type of pareidolia, in which people see faces or other meaningful patterns in ambiguous images.
