The loudness of our thoughts or how we imagine saying, something influences how we judge the loudness of real, external sounds.
Our thoughts are silent to others but not to ourselves in our own heads, so the loudness in our thoughts influences the loudness of what we hear.
After imagined speaking in the mind, the actual sounds you hear become softer, the louder the volume during imagery, the softer perception will be.
This is because imagery and perception activate the same auditory brain areas. The preceding imagery already activates the auditory areas once when the same brain regions are needed for perception, they will be tried and respond less .
This is because perception is a result of interaction between our cognition and processing of external stimulation processes.
This is because human beings not only receive and analyze upcoming external signals passively but also interpret and manipulate them actively to form perception.
