Obscure Auditory Dysfunction (OAD) is defined as a clinical referral for self-reported auditory disability with no audiometric abnormality by stringent criteria. In stage 2 of a case control study of OAD, we have 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. Paired logistic regression analysis optimally… 

Validation of parameters for assessing Obscure Auditory Dysfunction--robustness of determinants of OAD status across samples and test methods.

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 clinical test battery for obscure auditory dysfunction (OAD): development, selection and use of tests.

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.

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.

A critical review of King-Kopetzky syndrome: Hearing difficulties, but normal hearing?

Advances in the development of sensitized and objective assessments of subclinical auditory dysfunction in patients with King-Kopetzky syndrome are reviewed to provide guidelines on the pathogenesis and lead towards a better understanding of KKS.

Characterisation of disordered auditory processing in adults who present to audiology with hearing difficulties in presence of normal hearing thresholds : correlation between auditory tests and symptoms

The three validated questionnaires may help identify adults with normal hearing who need referral for APD assessment and correlations were noted among the scores of the three questionnaires and the APD tests.

The Role of a Family History in King Kopetzky Syndrome (Obscure Auditory Dysfunction)

In 82 consecutive patients with KKS and normal middle ear function, the performance of those with and without a family history of hearing impairment on a number of sensitized tests was compared.

Understanding Self-reported Hearing Disability in Adults With Normal Hearing

Although participant audiometric thresholds were within normal limits, higher thresholds, history of impulse noise exposure, and FM detection predicted self-reported HD, with a sensitivity of 89% and specificity of 86%.

The Relation Between Cochlear Neuropathy, Hidden Hearing Loss and Obscure Auditory Dysfunction

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.

Working Memory and Extended High-Frequency Hearing in Adults: Diagnostic Predictors of Speech-in-Noise Perception

It is suggested that both peripheral (auditory) and central (cognitive) factors contribute to the speech-in-noise difficulties reported by normal hearing adults in their mid-adult years.

Causal attributions in King-Kopetzky syndrome

The findings suggest that participants regard immunity and risk related causes of hearing difficulties as pre-dominant and psychological factors were not considered to be causal for hearing difficulties.



The clinical assessment of obscure auditory dysfunction--1. Auditory and psychological factors.

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,

Determinants of objective and subjective auditory disability in patients with normal hearing

It was concluded that performance measures could be used to validate reports of disability/handicap, but that personality factors should be taken into account when interpreting such reports.

Self-reported disability and handicap in the population in relation to pure-tone threshold, age, sex and type of hearing loss.

A self-administered questionnaire concerning auditory disability and handicap was completed by 1691 subjects who were part of a two-stage random sample of the UK adult population, finding little evidence for the concept of a 'low fence' in the relationship between impairment and either disability or handicap.

Lack of association between otoacoustic emissions and hearing difficulty in subjects with normal hearing thresholds.

Any cochlear component of OAD does not appear to affect the function of the outer hair cells sufficiently to modify EOAEs materially.

Auditive and cognitive factors in speech perception by elderly listeners. II: Multivariate analyses.

It was found that the balance between auditive and cognitive contributions to speech perception performance did not change with age, and the deterioration of speech perception in the elderly consists of two statistically independent components.

Auditive and cognitive factors in speech perception by elderly listeners.

It was found that the balance between auditive and cognitive contributions to speech perception performance did not change with age, and the deterioration of speech perception in the elderly consisted of a general performance decrement due to reduced mental efficiency.

Selective Dysacusis — A Preliminary Report

Findings indicated that frequency specific responsiveness of the cochlea may be affected before conventional behavioural tests reveal abnormalities.

A Short Clinical Diagnostic Self-rating Scale for Psychoneurotic Patients

It was decided to design and attempt to validate a self-rating scale adapted to these categories, taking the patient 5–10 minutes to complete and capable of being rapidly scored by the doctor or an assistant.

A pseudo free-field measure of auditory disability.

A procedure has been developed by recording the signals from two Zwislocki couplers in a KEMAR mannikin to produce a headphone-presented set of speech material containing the important dichotic cues present in free field listening that enables readily calibrated and experimentally controllable conditions to be set up to measure aspects of auditory disability and, for example, its alleviation via amplification.

Difficulties with speech intelligibility in noise in spite of a normal pure-tone audiogram.

A group of 15 patients with complaints of having difficulties in understanding speech, especially in noisy surroundings in spite of (nearly) normal pure-tone audiograms, was subjected to a battery of
