Eustachian tube dysfunction can be caused by a number of factors. Some common causes include the flu, allergies, a cold, and sinus infections. [6] In patients with chronic ear disease such as cholesteatoma and chronic discharge, studies showed that they have obstructive pathology at the ear side of the Eustachian tube.
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".
Patients describe a wide range of sounds that affect balance: the 'rattle' of a plastic bag; a cashier tossing coins into the register; a telephone ringing; a knock at the door; music; the sound of children playing and even the patient's own voice are typical examples of sounds that can cause a loss of balance when this condition is present ...
"Ear infections can interfere with sound transmission, causing a ringing sensation in the ear," Lewis says. "Infections cause inflammation and fluid buildup, which disturb the auditory system ...
The most common cause of hyperacusis is overexposure to excessively high decibel (sound pressure) levels, which can cause acoustic trauma. [1] An acoustic shock , which can lead to symptoms such as hyperacusis and ear pain, can also occur after exposure to an unexpected moderately loud to loud noise, even if this does not necessarily result in ...
For example, very curvy ear canals, narrow ear canals, or surgical ears are more prone to earwax buildup. When wax builds up, it causes muffled hearing, tinnitus, or aural fullness (plugged-up ...
Unsafe levels of noise can be as little as 70 dB (about twice as loud as normal conversation) if there is prolonged (24-hour) or continuous exposure. 125 dB (a loud rock concert is ~120 dB) is the pain level; sounds above this level cause instant and permanent ear damage. [citation needed] Noise and ageing are the primary causes of presbycusis ...
Auditory processing disorder (APD), rarely known as King-Kopetzky syndrome, is a neurodevelopmental disorder affecting the way the brain processes sounds. [2] Individuals with APD usually have normal structure and function of the ear, but cannot process the information they hear in the same way as others do, which leads to difficulties in recognizing and interpreting sounds, especially the ...
