Sudden sensorineural hearing loss (SSHL) is a change to the inner ear hearing status. SSNHL is a change of 30 dB HL or greater at three adjacent frequencies within 72 hours. For example, if your ...
Sudden sensorineural hearing loss (SSHL or SSNHL), commonly known as sudden deafness, occurs as an unexplained, rapid loss of hearing—usually in one ear—either at once or over several days. Nine out of ten people with SSHL lose hearing in only one ear. It should be considered a medical emergency.
The implant then sends sound vibrations to the cochlea of the normal hearing ear through the skull via bone conduction. [11] The ADHEAR bone conduction system is a non-surgical device that sticks to the skin behind the ear. It vibrates to send sound vibrations through the skin and the skull bone to the cochlea of the normal hearing ear. [12]
If one ear has normal thresholds while the other has sensorineural hearing loss (SNHL), diplacusis may be present, as much as 15–20% (for example 200 Hz one ear => 240 Hz in the other). [citation needed] The pitch may be difficult to match because the SNHL ear hears the sound "fuzzy". Bilateral SNHL gives less diplacusis, but pitch ...
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 ...
[2] [10] Hearing loss is diagnosed when hearing testing finds that a person is unable to hear 25 decibels in at least one ear. [2] Testing for poor hearing is recommended for all newborns. [ 8 ] Hearing loss can be categorized as mild (25 to 40 dB ), moderate (41 to 55 dB), moderate-severe (56 to 70 dB), severe (71 to 90 dB), or profound ...

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 ().
