A pure tone audiometry hearing test is the gold standard for evaluation of hearing loss or disability. [ medical citation needed ] Other types of hearing tests also generate graphs or tables of results that may be loosely called 'audiograms', but the term is universally used to refer to the result of a pure tone audiometry hearing test.
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]
A hearing test administered by a medical doctor, otolaryngologist (ENT) or audiologist including pure tone audiometry and speech recognition may be used to determine the extent and nature of hearing loss, and distinguish presbycusis from other kinds of hearing loss. Otoacoustic emissions and evoked response testing may be used to test for audio ...
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.
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).
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.
Auditory neuropathy is sometimes difficult to catch right away, even with these precautions in place. Parental suspicion of a hearing loss is a trustworthy screening tool for hearing loss, too; if it is suspected, that is sufficient reason to seek a hearing evaluation from an audiologist. [10]
The diabetes that accompanies the hearing loss can be similar to Type 1 diabetes or Type 2 diabetes; however, Type 1-like diabetes is the more common form of the two. MIDD has also been associated with a number of other issues including kidney dysfunction, gastrointestinal problems , and cardiomyopathy .
