A cause is traumatic noise exposure that damages hair cells in the inner ear. [33] Some evidence suggests that long-term exposure to noise pollution from heavy traffic may increase the risk of developing tinnitus. [34] When there does not seem to be a connection with a disorder of the inner ear or auditory nerve, tinnitus can be called "non-otic".
Hyperacusis is an increased sensitivity to sound and a low tolerance for environmental noise. Definitions of hyperacusis can vary significantly; it often revolves around damage to or dysfunction of the stapes bone, stapedius muscle or tensor tympani ().
As does any object facing a sound, the ear acts as a passive filter, although the inner ear is not an absolute passive filter because the outer hair cells provide active mechanisms. A passive filter is a low pass : the high frequencies are more absorbed by the object because high frequencies impose a higher pace of compression-decompression to ...

Before losing consciousness, the individual frequently experiences early signs or symptoms such as lightheadedness, nausea, the feeling of being extremely hot or cold (accompanied by sweating), ringing in the ears, an uncomfortable feeling in the heart, fuzzy ...
The ear canal volume indicates whether a perforation in the eardrum (tympanic membrane) may be present. The middle ear pressure indicates whether any fluid is present in the middle ear space (also called "glue ear" or "otitis media with effusion"). Compliance measurement indicates how well the eardrum and ossicles (the three ear bones) are moving.
The inner ear itself can be surgically removed via labyrinthectomy, although hearing is always completely lost in the affected ear with this operation. [35] The surgeon can also cut the nerve to the balance portion of the inner ear in a vestibular neurectomy. The hearing is often mostly preserved; however, the surgery involves cutting open into ...
Patulous Eustachian tube is a physical disorder. The exact causes may vary depending on the person and are often unknown. [5] Weight loss is a commonly cited cause of the disorder due to the nature of the Eustachian tube itself and is associated with approximately one-third of reported cases. [6]
