When wearing stereo headphones, people with unilateral hearing loss can hear only one channel, hence the panning information (volume and time differences between channels) is lost; some instruments may be heard better than others if they are mixed predominantly to one channel, and in extreme cases of sound production, such as complete stereo ...
Musical ear syndrome (MES) is a condition seen in people who have hearing loss and subsequently develop auditory hallucinations. "MES" has also been associated with musical hallucinations , which is a complex form of auditory hallucinations where an individual may experience music or sounds that are heard without an external source.

Nearly one in four adults had audiometric results suggesting noise-induced hearing loss. Almost one in four adults who reported excellent or good hearing had a similar pattern (5.5% on both sides and 18% on one side). Among people who reported exposure to loud noise at work, almost one third had such changes. [129]
Cases are commonly found in the elderly, but in one case a 29-year-old woman reported hearing music for one week. Prior to her hallucinations, the patient had undergone surgery for intraventricular and intracranial hemorrhages. Following her recovery, she mentioned the onset of hallucinations followed by headaches. [6]
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 ...
The Oticon Real is an over-the-ear hearing aid that comes in two styles: behind-the-ear (BTE) with the receiver in canal (RIC) or behind-the-ear where the hearing aid hooks over the top of your ...
The result is a tympanogram showing ear canal volume, middle ear pressure and eardrum compliance. Normal middle ear function (Type A tympanogram) with a hearing loss may suggest presbycusis. Type B and Type C tympanograms indicate an abnormality inside the ear and therefore may have an additional effect on the hearing.
Modern over-the-ear headphones offer incredible sound and impressive noise-cancelling, often for a surprisingly low price. (Photos: 1More, Soundcore, Sony)
