  That was my first thought as well, but it’s a thing. One of those times I learned the definition of a word wasn’t exactly what I thought it was (or, more precisely that the commonly used definition of a word actually needs a technical/clinical qualifier to be complete, such as “subjective” in this case, because other qualified definitions exist). https://www.medlink.com/articles/objective-tinnitus https://www.medlink.com/articles/objective-tinnitus “Objective tinnitus is a perceived sensation of sound that occurs in the absence of external acoustic stimulation, but it can also be heard by the examiner (eg, by placing a stethoscope over the patient's external auditory canal). Objective tinnitus can occur either from perception of an abnormal somatosound or abnormal perception of a normal somatosound. Objective tinnitus is much less common than subjective tinnitus, but it often has an identifiable cause and may be curable, whereas subjective tinnitus is often idiopathic and is seldom curable.”

  The ears are capable of generating sound. See: https://en.wikipedia.org/wiki/Otoacoustic_emission https://en.wikipedia.org/wiki/Otoacoustic_emission The main function of this system is to protect the ear from loud sounds—noise canceling and/or modulate sensitivity as a function of spectrum.
