Tinnitus is a variety of sound that is heard when no corresponding external sound is present. [1] Nearly everyone experiences faint "normal tinnitus" in a completely quiet room; but it is of concern only if it is bothersome, interferes with normal hearing, or is associated with other problems. [6]
Anatomy of the human ear. Conductive hearing loss (CHL) occurs when there is a problem transferring sound waves anywhere along the pathway through the outer ear, tympanic membrane (eardrum), or middle ear (ossicles). If a conductive hearing loss occurs in conjunction with a sensorineural hearing loss, it is referred to as a mixed hearing loss.
Sensorineural hearing loss (SNHL) is a type of hearing loss in which the root cause lies in the inner ear, sensory organ (cochlea and associated structures), or the vestibulocochlear nerve (cranial nerve VIII). SNHL accounts for about 90% of reported hearing loss. [citation needed] SNHL is usually permanent and can be mild, moderate, severe ...
Wax is normal and good for the ear. “A lot of people associate ear wax with being dirty or unclean, so there’s this kind of aggressive need to keep the ears cleaned out in some way, but we ...
Ménière's disease (MD) is a disease of the inner ear that is characterized by potentially severe and incapacitating episodes of vertigo, tinnitus, hearing loss, and a feeling of fullness in the ear. [3][4] Typically, only one ear is affected initially, but over time, both ears may become involved. [3] Episodes generally last from 20 minutes ...
Bone conduction. Bone conduction is the conduction of sound to the inner ear primarily through the bones of the skull, allowing the hearer to perceive audio content even if the ear canal is blocked. Bone conduction transmission occurs constantly as sound waves vibrate bone, specifically the bones in the skull, although it is hard for the ...
Otitis media is a group of inflammatory diseases of the middle ear. [ 2 ] One of the two main types is acute otitis media (AOM), [ 3 ] an infection of rapid onset that usually presents with ear pain. [ 1 ] In young children this may result in pulling at the ear, increased crying, and poor sleep. [ 1 ] Decreased eating and a fever may also be ...
Wikiversity has learning resources about Global Audiology. Hearing loss may be caused by a number of factors, including: genetics, ageing, exposure to noise, some infections, birth complications, trauma to the ear, and certain medications or toxins. [2] A common condition that results in hearing loss is chronic ear infections. [2]
