Auditory

ears

While some disorders like Misophonia may be neurological, and others may be a part of the physical body, this page shows disorders that for whatever reason are associated with the ears. Hearing loss, and other general conditions are not listed as they are heavily researched and not necessary to advocate along-side sensory disorders.

 

Tinnitus – the term used for noises or sounds which are heard in one or both ears or in the head which do not come from an external source. They are often described as a high-pitched ringing but can also be described as a buzzing, hissing, pulsing, whistling, roaring, or various other sounds. Tinnitus can be very mild in loudness and only noticeable in a quiet room or it can become extremely loud and annoying to the point where the sufferer hears nothing else. It can be present all of the time or occur intermittently

 

Auditory Processing Disorder – Typically the brain processes sounds seamlessly and almost instantly. Most people can quickly interpret what they hear. But with APD, some kind of glitch delays or “scrambles” that process. To a person with APD, “Tell me how the chair and the couch are alike” might sound like “Tell me how a cow and hair are like.”

 

Misophonia –  a neurological disorder in which auditory (and sometimes visual) stimuli are misinterpreted within the central nervous system. However, misophonia and what causes misophonia is still something of a mystery. Common sounds that are bothersome are: chewing, coughing, breathing, tapping, and pen clicking

 

Sensory Over-Responsivity – Those who experience sensory over-responsiveness are also commonly referred to as ‘sensory defensive’. A person with a hypersensitivity to sensory input will experience the world as a threatening, painful, and/or scary place. They are often hyper-vigilant and under a lot of stress, and may experience frequent meltdowns. They truly have weak filters for sensory input. This often includes sounds (as well as other senses)

 

Autism – Audiologists have found that people on the spectrum may have enhanced perception to certain sounds, impaired perception of other sounds, or a combination of hyper (overly sensitive) or hypo (unable to pick up on) sensitivity to sounds

 

Hyperacusis – individuals have a collapsed tolerance to normal environmental sound.  The term commonly used to describe this condition is ‘hyperacusis’.  Hyperacusis can come on gradually or occur suddenly where the patient finds themself in a state of crisis.  Patients who have a collapsed tolerance to sound need to have their Loudness Discomfort Levels (LDL’s) established by a hearing healthcare professional

 

Recruitment  There are many more individuals who have recruitment.  Recruitment is the a rapid growth of perceived loudness for sounds in the pitch region of a person who has hearing loss.  This phenomenon occurs because at some decibel level, the normal hair cells adjacent to the damaged hair cells (corresponding to the frequency of a hearing loss) are “recruited”
