Hearing loss is a partial or total inability to hear. [5] Hearing loss may be present at birth or acquired at any time afterwards. [6] [7] Hearing loss may occur in one or both ears. [2] In children, hearing problems can affect the ability to acquire spoken language, and in adults it can create difficulties with social interaction and at work. [8]
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 ...
General hearing loss affects close to 10% of the global population. [42] In the United States alone, it is expected that 13.5 million Americans have sensorineural hearing loss. Of those with sensorineural hearing loss, approximately 50% are congenitally related.
Autoimmune inner ear disease (AIED) was first defined by Dr. Brian McCabe in a landmark paper describing an autoimmune loss of hearing. [2] The disease results in progressive sensorineural hearing loss (SNHL) that acts bilaterally and asymmetrically, and sometimes affects an individual's vestibular system.
Another source has estimated that communication disorders—a larger category, which also includes hearing disorders—affect one of every 10 people in the United States. [ 13 ] ASHA has cited that 24.1% of children in school in the fall of 2003 received services for speech or language disorders—this amounts to a total of 1,460,583 children ...
Blindness – A link between communication skills and visual impairment with children who are blind is currently being investigated. [19] Deafness/frequent ear infections – Hearing impairments during language acquisition may lead to spoken language problems. Children with frequent ear infections may temporarily develop problems pronouncing ...
Dysacusis is a hearing impairment characterized by difficulty in processing details of sound due to distortion in frequency or intensity rather than primarily a loss of the ability to perceive sound. [1] The term is sometimes used to describe pain or discomfort due to sound, a condition also known as auditory dysaesthesia. [2]
Auditory neuropathy spectrum disorder (ANSD) is a specific form of hearing loss defined by the presence of normal or near-normal otoacoustic emissions (OAEs) but the absence of normal middle ear reflexes and severely abnormal or completely absent auditory brainstem response (ABRs).
