Profound unilateral hearing loss is a specific type of hearing loss when one ear has no functional hearing ability (91 dB or greater hearing loss). People with profound unilateral hearing loss can only hear in monaural (mono). Profound unilateral hearing loss or single-sided deafness, SSD, makes hearing comprehension very difficult.
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]
The Rinne test ( / ˈrɪnə / RIN-ə) is used primarily to evaluate loss of hearing in one ear. [ 1] It compares perception of sounds transmitted by air conduction to those transmitted by bone conduction through the mastoid. Thus, one can quickly screen for the presence of conductive hearing loss. [ 2]

Absolute threshold of hearing. The absolute threshold of hearing ( ATH ), also known as the absolute hearing threshold or auditory threshold, is the minimum sound level of a pure tone that an average human ear with normal hearing can hear with no other sound present. The absolute threshold relates to the sound that can just be heard by the ...

Diplacusis, also known as diplacusis binauralis, binauralis disharmonica or interaural pitch difference (IPD), is a hearing disorder whereby a single auditory stimulus is perceived as different pitches between ears. It is typically experienced as a secondary symptom of sensorineural hearing loss, although not all patients with sensorineural ...
A photoreceptor cell is a specialized type of neuroepithelial cell found in the retina that is capable of visual phototransduction. The great biological importance of photoreceptors is that they convert light (visible electromagnetic radiation) into signals that can stimulate biological processes. To be more specific, photoreceptor proteins in ...
