We define obscure auditory dysfunction (OAD) as the clinical presentation of reported difficulty understanding speech in the presence of noise accompanied by clinically "normal" hearing thresholds, and no other obvious cause. The term deliberately avoids particular pathophysiological connotations. A detailed characterization of such patients was undertaken as the basis for future diagnosis and management of OAD by clinicians. Twenty patients were compared with 20 pairs of controls (matched for…

The clinical assessment of "Obscure Auditory Dysfunction" (OAD) 2. Case control analysis of determining factors.
TLDR
Stage 2 of a case control study of OAD has confirmed the general finding of stage 1 that OAD is multifactorial; compared with controls, patients as a group have a genuine performance deficit for understanding speech in noise, accompanied by personality-related factors.
A clinical test battery for obscure auditory dysfunction (OAD): development, selection and use of tests.
TLDR
A demographic and clinical characterization of a sample of 50 OAD patients is summarized, new norms on the tests in the version issued, and a test package developed from a case-control research study that can be routinely used with Oad patients is described.
A pilot investigation of high-frequency audiometry in obscure auditory dysfunction (OAD) patients.
TLDR
It is proposed that OAD in fact, is the product of an ultra-high-frequency hearing impairment and its psychoacoustic sequelae and the degree to which it can be used may be limited due to the large intersubject variability in HFA thresholds in the normal population.
Validation of parameters for assessing Obscure Auditory Dysfunction--robustness of determinants of OAD status across samples and test methods.
TLDR
A study on a further 59 new OAD patients and 64 unmatched controls, using the tests in the form present in the test package, plus certain others, confirms the validity of the three-factor model of OAD status and the utility of the clinical test package based upon it.
A critical review of King-Kopetzky syndrome: Hearing difficulties, but normal hearing?
King-Kopetzky syndrome (KKS) is the condition in which an individual complains of having difficulties understanding speech in background noise but has normal hearing thresholds on pure tone…
Processing of Speech in Complex Listening Environments by Individuals with Obscure Auditory Dysfunction
Obscure auditory dysfunction (OAD) is a disorder for which patients report excessive amounts of difficulty understanding speech in the presence of background noise, despite no obvious evidence of…
Subcategories of Patients with King-Kopetzky Syndrome
TLDR
In a study on 110 consecutive patients with King-Kopezky syndrome referred to the Welsh Hearing Insitute, subjects were subdivided into seven subcategorization based on sensitized measures of auditory dysfunction and on psychological assessment, which provides further understanding of the basis ofKing-Kopetzky syndrome.
Auditory processing in patients with structural lesions of the brain
This thesis investigated structure versus function in the central auditory nervous system (CANS) by using the lesion study approach and by utilising a validated clinical test battery for the…
The Relation Between Cochlear Neuropathy, Hidden Hearing Loss and Obscure Auditory Dysfunction
TLDR
Widespread loss of auditory nerve fibers can take place without hair cell loss or threshold elevation, as a result of either noise exposure or ageing, leading to perceptual deficits without affecting the audiogram.
Hearing complaints of patients with King-Kopetzky syndrome (obscure auditory dysfunction).
TLDR
The open-ended hearing problem questionnaire appears to be a useful tool that can be used to high-light the speech hearing disability encountered by patients with King-Kopetzky syndrome.
